REPO Mutant Enemies

REPO Mutant Enemies turns the 29 vanilla enemy families into rare, tougher variants with 31 built-in ability kits. Huntsman has two mutually exclusive variants, Deadeye and Ricochet; Tick has Blood Bank or Power Leech. If Wesley's Enemies is installed, all six of its current characters also receive a dedicated mutation, for 37 variants in that setup. Mutants retain their original models and basic movement, gain reworked attacks and a bright colour aura, and show their mutant name when grabbed.

This is a synchronized gameplay mod: every player in the lobby must install the same build. Update everyone to the same distribution package together; do not mix versions or builds. The lobby host's mutation-generation settings control the chance, surge interval, disabled list and per-level cap. Keep any other non-synchronized gameplay settings aligned between players.

New in 1.3.3: clearer abilities, less screen clutter

• Trickster: no tower or extra leap attack. Nearby unattended valuables grow purple feet and run away for up to 6.5 seconds. Grab the valuable, stun or kill the Gnome to stop the curse. The original item keeps its price and mass; weapons, shop equipment and carts are excluded.
• Kaleidoscope: ceiling laser hits now place the prism on the combatants' floor, not the ceiling.
• Aftershock: a visible nearby player can trigger the shadow corridor without waiting for a slap. A 6.5-second cooldown prevents overlapping claps; stun, death and despawn cancel pending traps.
• Hydroshock: visible water-pressure buildup, faster first cast and waves, 12 m / 32 per wave, a 0.65-second warning and a separate 4.5-second cooldown. It only targets players its waves can reach.
• Removed the mod's activation/countdown text overlays and overhead digits, including Blood Bank and the optional Wesley mutations. Blood Bank's link reddens and pulses as its debt comes due. World-space shapes, lights, sounds, native game UI and grabbed mutant names remain.

Existing unchanged Hydroshock radius/damage defaults migrate once. Customized settings are retained. Match the same 1.3.3 distribution build across the lobby; real separate-PC playtesting is still needed.

Previous in 1.3.2: bug fixes and balance improvements

• Redline: reliable warned charges during pursuit, with floor checks at its feet. Its delayed trail still cannot damage or knock back enemies.
• Necromancer: fewer, slower, short-lived summons; single-hit skulls, a caster-wide damage cooldown, and a brief escapable slow instead of near-immobilization. Stolen-head empowerment stays.
• Deathlight: visible gold body aura, attacks from ceiling roam, and warned floor lights even while stationary. Stronger default floor/slam damage: 25/80.
• Chatterjaw: full floor-sector warning and closing teeth, 75 damage, six-second cadence.
• Big Bang: every member of an admitted natural three-Banger pack mutates together, subject to the host's total cap. Snatcher: default 40 damage. Belladonna: waves retained, text HUD removed.

1.3.2 includes Glutton counterplay, safe loot retention and HP initialization fixes. Existing custom tuning is preserved; only unchanged old Snatcher and Deathlight defaults migrate once.

Glutton now keeps swallowed valuables safely deactivated throughout a temporary despawn, including when its entire enemy rig is inactive. Swallowed loot uses the game's safe storage position, not the out-of-map destruction zone. Its permanent mass growth survives native stun/grab mass resets, and returning a meal updates the baseline without cancelling a temporary mass override. A former guest becoming host no longer triggers Glutton's initial HP refill. Reworked mutants also initialize HP before a spawn-frame hit, so their first update cannot erase damage already accepted by the game. Existing configs and the four-second feeding pause are retained.

Separate-PC reception, late-join full-belly state, live host migration and natural-play balance still need a multiplayer playtest. Controlled native probes do not replace a session with friends.

Fight Glutton to recover loot

Each hit that actually damages a living Glutton returns one of its swallowed valuables and removes that item's health, damage and mass growth. Glutton stops eating for 4 seconds after damage; further hits restart the pause. Returned valuables also cannot be eaten by another Glutton during this window and receive brief damage protection. Killing it still returns the rest. Set [Glutton] HurtEatCooldownSeconds to adjust the pause. Existing configs receive this new setting without resetting your other tuning. Also fixes the missing optional argument in BerserkerEnemies Reborn's solo despawn call, so a Berserker Glutton can finish its death and return the remaining loot normally.

New in 1.3.1: limit mutants per level

[Mutation] MaxMutantsPerLevel limits how many distinct enemy bodies can become mutants during one level. It defaults to 6, including fifth-level surges and optional Wesley enemies. Level 40 is a surge level under the default interval, so its mutation roll is 100%, but the new cap leaves later enemies normal. Set the cap lower for a gentler run, or to 0 for the previous unlimited behavior. The existing chance, surge and disabled-mutant settings still apply.

[Mutation]
MaxMutantsPerLevel = 3

This counts mutants admitted over the whole level, not just those alive at once. A respawn keeps its previous mutation without using another slot. A natural Trickster group uses four slots together; if fewer than four remain, that group stays normal. A natural Big Bang triple uses three together and stays normal below three remaining slots. Additional squad members use one each. Set the limit on the host; guests automatically use the host's limit and other mutation-generation settings for that room. Choose settings before opening the lobby.

What is new in 1.3.0

• Reworked Deathgaze, Poltergeist, Trickster, Redline, Resonance, Necromancer, Heartbreak, Deathlight and Parallax around visible world actions. Closed Deathgaze eyes are invulnerable; Redline's delayed trail explosions cannot damage or knock back enemies.
• Deadeye now uses the real Photon Blaster damage pipeline along the full beam. House Edge restores the five 1.1.0 colour rules; Ricochet keeps its reflected-shot kit without its HUD.
• Added Power Leech as a second, mutually exclusive Tick mutation. Within 14 m it drains every nearby battery-powered item, including equipped inventory slots and dropped items, at 25 percentage points per second. Its cyan pulse marks the area; leaving it or stunning the Tick stops the drain.
• Added Chatterjaw, a dedicated Headman mutation: a teeth-chatter warning marks a high, 130-degree frontal bite for 65 damage. Crouch or crawl under it, leave the fixed arc, use solid cover, or stun it.
• Improved the HUD-free world tells after a real GPU visual audit: Resonance now previews its complete outbound/reflected route, and Parallax leaves a guaranteed-visible cyan humanoid echo with a direction arrow.
• Fixed Trickster's collapse recovery/strike ordering, solo Poltergeist object selection, and Redline's charge duration with custom warnings. Breakable vines, summons and thorns respect native weapon wall checks and hit intervals; thorns can also be hit correctly near their top. House Edge's solo black rule now always retains its intended upward launch instead of being weakened by the player's own collider. Native enemy-to-enemy hurt checks also ignore the brief spawn frame before a target's physics object is ready, preventing an intermittent base-game HurtCollider exception without changing valid hits.
• Corrected the base names: Faultline = Trudge, Aftershock = Loom, Parallax = Shadow Child.
• Added six optional mutations for Wesley's Enemies: Hydroshock, Flashpoint, Scrambler, Crossfire, Barrage and Effigy. They are registered only when Wesley's mod is actually installed.
• Added BerserkerEnemies Reborn compatibility. Berserker now recognizes renamed mutant enemies, so one enemy can keep both its mutation ability and its Berserker modifiers.
• Restored the bug-report/request survey link in this description.
• Deterministic rolls and guaranteed fifth-level surges remain.

The 31 built-in mutants

1. Boomday Boy — Birthday Boy, orange. It survives recurring proximity blasts and turns its balloons into visible contact mines. Killing it also detonates the core.
2. Poltergeist — Mentalist, violet. Possesses up to three loose objects, warns their paths, then rams them for 50 damage with a shared 0.8-second hit interval. Empty rooms get visible spectral objects. Grab an object or stun the Mentalist to interrupt it; weapons, carts and real death heads are excluded.
3. Meltdown Crew — Cleanup Crew, toxic green. Each throw becomes a synchronized three-head volley: one slow, one normal, and one fast homing bomb head.
4. Snatcher — Hidden, violet. The instant it begins carrying a victim, it moves that player to a verified floor point elsewhere on the map and deals 40 damage.
5. Deathgaze — Peeper, red. Its closed eye is invulnerable. After a 1.2-second wind-up it opens and flashes: looking directly at the visible eye deals 60 damage. Look away or use solid cover, then attack during the three-second open-eye recovery. No exposure meter or forced camera turn.
6. Deadeye — Huntsman, laser blue. Every shot fires the real Photon Blaster beam, retaining the weapon's native damage, hit cooldowns and force. Every player touching its full length can be hit; players do not shorten the beam, but solid scenery and loot stop it. The old target-only 55-damage hit is gone.
7. Trickster — Gnome, purple. Its natural quartet shares a mutation roll without stacking or cloning. Each Gnome can make one nearby unattended valuable grow purple feet and flee for up to 6.5 seconds. Grab the valuable, stun or kill the Gnome to stop it. Price/mass remain unchanged; native ground attacks stay 50.
8. Fenrir — Elsa, icy blue. The dog freezes for a 3.5-second buildup, then transforms in a 60-damage shockwave.
9. Big Bang — Banger, hot pink. All three natural pack members share one mutation roll and become twice-sized chain-reaction threats (80 damage). The group requires three available mutation slots; configured extra squad members also use slots.
10. Glutton — Animal, amber. It swallows loose valuables and gains health, impact damage, and mass based on their size. Damage returns one valuable and removes its growth, then pauses eating for 4 seconds. Returned loot is briefly protected from damage and re-swallowing. Kill it to recover the remaining haul.
11. Alpha — Apex Predator, gold. After a five-second buildup it swaps with another enemy and howls, redirecting the whole map toward its prey for 15 seconds. When alone, it swaps with loose loot or safely relocates, so the transformation never intentionally collapses into an empty ability.
12. Belladonna — Bella, magenta. Every bell sends a 0.9-second-warned floor wave that must be jumped. Up to four nearby valuables stay in place and answer with staggered cyan echo waves; the primary wave always fires even in an empty room. Read the rings themselves; there is no text HUD.
13. Flambé — Chef, burning orange. Every tumble throws four real armed shop grenades in the cardinal directions. Their blasts hurt players but not enemies.
14. Redline — Reaper, red. Warns for one second, then charges in a fixed direction for 60 contact damage. Two seconds after the charge ends, its actual three-metre-wide trail explodes for 75 once per player. These blasts apply no damage or knockback to any enemy and do not damage or push props.
15. Singularity — Bowtie, blue violet. Its yell pulls players inward while real valuables orbit the gravity well, then slingshots captured debris at players with boosted impact.
16. Faultline — Trudge, lava orange. Each mace attack leaves three warned floor fractures. The cracks stay dangerous for 7.5 seconds and deal 40 while touched, changing how the room can be crossed.
17. Kaleidoscope — Clown, electric cyan. A laser impact opens three coloured prism blades. After the warning they rotate through 120 degrees; orbit with the gaps rather than crossing a blade (40 damage).
18. House Edge — Gambit, casino gold. Restores the five 1.1.0 rules using the settled wheel colour: red punishes movement (55 after a 0.8-second warning), yellow drops held items and prevents grabbing for four seconds, green heals nearby enemies by up to 40 and gives 40% resistance for six seconds, white launches players four times, and black rotates valid player positions (an impulse when alone). Colour rings mark the affected room; the later SAFE pocket minigame is removed.
19. Resonance — Upscream, resonant blue. After a one-second tell, a six-metre-wide sound wave travels through the room and reflects once from a wall. It deals 55 at most once per player on each leg. A pulsing cyan guide previews the complete outbound and reflected route; read the moving wave and dodge its return. There is no stillness rule or HUD meter.
20. Blood Bank — Tick, green. Stolen health heals and shields nearby enemies. Each completed feeding also creates a visible six-second blood debt for 45 damage; stun or kill that Tick to cancel the debt.
21. Railgun — Rugrat, charged cyan. Its normal valuable throw becomes a fast glowing projectile with 9x native player-impact damage.
22. Blackout — Robe, near-black violet. Hostile states suppress non-directional room and carried lights in 16 m and increase pursuit speed to 1.75x. Overlapping fields restore each light only after all release it.
23. Contagion — Spewer, toxic green. Puke infects up to three valuables into visible grab traps and leaves a warned 4 m spore cloud for eight seconds. Leave the visible green ring to recover. Two seconds of exposure deals 50; retreat or solid cover drains exposure twice as fast.
24. Necromancer — Headgrab, soul violet. Summons two destructible skulls (20, then dissipate) and one floor hand (16 once, 55% movement for up to 0.8 seconds). All its summons share a 1.2-second damage cooldown per victim. A 1.5-second warning allows escape; summons expire after 6.5 seconds. Carrying a real death head raises caps to three/two and shortens casts from 11 to 9 seconds without consuming it. Its first lethal hit starts a three-second ritual: break the core, or it revives once at half HP.
25. Heartbreak — Heart Hugger, hostile pink. A warned, cuttable vine catches a player for 30, pulls them toward the mouth and bites for 50. Cut the vine, break sight with cover, or stun the source. Two breakable thorn barriers flank the target, leave escape gaps, and deal 20 per second on contact. No partner-matching HUD, paired chains or original gas capture.
26. Deathlight — Oogly, yellow. A gold halo follows its flying body. Ceiling movement or waiting leaves warned floor-light strips (25 per second; 0.8-second warning then four active seconds). From ceiling roam it locks a dive line, catches the first contacted player, lifts them toward the ceiling (maximum five metres) and slams for 80. Low ceilings shorten the lift; obstruction, death or stun releases it. Native wrestling/fall damage is suppressed during this carry.
27. Aftershock — Loom, electric violet. Proximity closes two tall shadow walls around a lane aimed only at a visible player and clipped at the first wall. Leave the corridor before the final clap or take 60, drop the held object, and get thrown from the corridor.
28. Parallax — Shadow Child, cyan. Teleport departure leaves a bright humanoid afterimage at the old position. A white-edged six-metre direction arrow warns for one second, then strikes once for 65. Move out of that fixed line. Arrivals and initial spawns do not create a second echo, and no HUD is needed.
29. Ricochet — alternate Huntsman, amber. Retains up to three wall reflections across a maximum 60 m path and one 60-damage hit per caught player. Its 0.9-second tell now uses a pulsing, whitening world-space path, sound and bounce flashes instead of a HUD. Closing doors still truncate later bounces.
30. Power Leech — alternate Tick, electric cyan. Its 14 m aura continuously drains 25 battery percentage points per second from every nearby battery item, not just the item in hand: equipped slots use their owner's position and dropped items use their own. Native battery bars and saved charge update. Stun the Tick or leave the cyan pulse; batteries are not disabled by a hidden input lock.
31. Chatterjaw — Headman, fang red. Every six seconds of active pursuit it marks an 8.5 m, 130-degree sector on the floor, with two rows of teeth closing at waist height. After 1.5 seconds it snaps for 75 damage. Crouch or crawl, leave the sector, use solid cover, or stun it. Native bites remain.

Six optional Wesley mutations

These variants are available only while Magic_Wesley-Wesleys_Enemies is installed. There is no hard dependency: without Wesley's mod, REPO Mutant Enemies loads normally and does not roll these families.

1. Hydroshock — Gusher, water blue. A visible 0.65-second water-pressure charge launches three fast expanding waves, 0.3 seconds apart, each reaching 12 m in 0.6 seconds for 32 damage. Jump or use cover. Casts begin quickly and repeat on a separate 4.5-second cooldown; long-distance unreachable targets are ignored.
2. Flashpoint — Roaster, burning orange. Captures a player's floor position and collapses a visible timer ring into a 55-damage burn zone. Leave the marked circle before it ignites.
3. Scrambler — Lost droid, signal green. Charges a 12 m EMP that damages and throws exposed players. Leave its radius or put a real wall between yourself and the droid.
4. Crossfire — Lost Destroyer, crimson. Locks two perpendicular, wall-clipped firing lanes onto a target's position. Leave both red lanes before they fire.
5. Barrage — Soldier, gold. Warns three slightly spread aim lanes, then fires them in sequence. A caught player takes at most one mutation hit per barrage.
6. Effigy — Voodoo, curse purple. Captures one player's position and draws a live tether. The target must escape the seven-metre curse circle before the countdown ends.

Mutation rules

• Ordinary chance is displayed level × ChancePerLevel (2.5% by default), capped at MaxChance (25%).
• Every GuaranteedSurgeInterval level (5 by default) uses a 100% roll for supported enemies, within MaxMutantsPerLevel (6 by default).
• DisabledMutants is respected even during a surge. Huntsman and Tick each choose one of their two enabled variants; disabling both for a family leaves that enemy normal.
• Wesley variants use the same deterministic chance, surge, health and DisabledMutants rules.
• A mutant has 2x health by default, gains another 0.05x per completed level, and caps at 3.5x.
• A stable Photon ViewID roll and the host's room-published mutation settings keep identities consistent across clients and ordinary respawns. Guests wait for the host settings before attaching mutants.

Configuration

The BepInEx configuration exposes the per-level mutant limit, mutation chance, surge interval, health scaling, aura brightness, DisabledMutants, and selected attack damage/range/timing controls, including all six optional Wesley kits. Names are comma- or semicolon-separated, for example:

[Mutation]
DisabledMutants = Big Bang; Parallax
GuaranteedSurgeInterval = 5
MaxMutantsPerLevel = 6

The mutation-generation settings above and reworked attack settings are synchronized from the host. Other attack tuning should still match between players. Old exposure/chain/photo/replay settings no longer control the replaced kits; existing configuration files are not deleted. There are no keyboard spawn bindings. Big Bang's gameplay squad remains; Trickster no longer creates children.

Installation and compatibility

Install BepInEx, REPOLib 4.2.0 or later, and this package through a mod manager. Manual installation places Matsu.MergedEnemyMod.dll under the profile's BepInEx/plugins directory. Everyone joining the lobby needs the same build and gameplay config because deterministic mutation attachment, visual warnings and player-owned damage resolution run on every client.

Wesley's Enemies is optional. When present, it must also be installed consistently across the lobby. The integration checks Wesley's actual runtime component before attaching a variant, so similarly named enemies from other mods are not changed.

BerserkerEnemies Reborn is optional and compatible. This mod extends Berserker's enabled-name list instead of replacing its controller. A mutant may therefore be selected as a Berserker and keep both kits. When both change health or damage, Berserker's later native health/collider-damage settings take precedence; custom mutation attacks retain this mod's damage settings. The mutation ability, aura and telegraphs remain active. Voodoo is included under Berserker's “modded enemies” setting.

Validation and known limits

The DLL included in this 1.3.3 package passed 21,163 production-rule assertions, game/PUN patch-contract checks, and isolated native-game probes: 223/223 without optional enemy mods and 260/260 with Wesley's Enemies 1.3.6 plus BerserkerEnemies Reborn 1.6.0 under a 15 FPS limiter (observed 13.46 FPS). Both native runs reported zero runtime errors and used the same DLL as this ZIP. Five current-build GPU captures of the repaired world-space tells were inspected at original size. Source/runtime checks confirm that the mod has no activation/countdown text renderer. Player enumeration has no fixed six-player limit. The previous 1.3.2 release and its 18,763 / 208 / 241-check evidence are preserved unchanged.

These are controlled solo tests using real game prefabs, physics, HP, weapons and batteries; some fixtures pause AI or use synthetic floors. They do not establish normal-play balance, distinct-account host/client synchronization, full-belly late joining, live host migration or seven-player gameplay. For an issue, include the enemy name, level, host/client role, settings and relevant BepInEx log.

REPO Mutant Enemies（日本語）

バニラ29系統の敵を、強化された31種類の標準突然変異へ変化させます。Huntsman は Deadeye と Ricochet、 Tick は Blood Bank と Power Leech のどちらか一方です。さらに Wesley's Enemies 導入時だけ、同MODの現行6キャラクター全員にも専用変異が追加され、 合計37種類になります。姿と基本移動は元の敵を引き継ぎ、攻撃を変化させます。固有色の強いオーラが付き、掴んだときには変異名が表示されます。

同期型のゲームプレイMODなので、ロビー全員が同じビルドを導入してください。 全員を同じ配布パッケージへ更新し、異なる版やビルドを混在させないでください。 変異率・確定階・無効化リスト・レベル上限はホスト設定が適用されます。同期対象外の攻撃設定は揃えてください。

1.3.3：検証内容の反映・画面テキスト整理

• Trickster：攻撃追加ではなく、放置した財宝に紫の足を生やして逃がすいたずらへ変更。 財宝をつかむ・小人をスタン・倒すと解除。原品の価値・重量を維持し、武器・カートには作用しません。
• Kaleidoscope：レーザーが天井に当たっても、プリズムはプレイヤーがいる階の床へ出すよう修正。
• Aftershock：平手攻撃を待たず、近くに見える相手がいれば通路を挟みます。6.5秒間隔で重複を防ぎ、 発生源のスタン・死亡・退場で予告中の攻撃も解除します。
• Hydroshock：発動前の水圧溜めを見える形にし、初動・予告・波の速度・再発動を高速化。 既定は12m・各32ダメージ・0.65秒予告・独立した4.5秒間隔。届かない遠方の相手には発動しません。
• MOD独自の発動メッセージ・頭上のカウントダウン数字を撤去。Blood Bankも赤く脈動する接続線で予告。 光・形・音の予告、バニラUI、掴んだ時の変異名は維持。

Hydroshockの旧既定の半径・威力だけ一度移行し、独自の調整値は維持します。 ロビー全員を同じ1.3.3配布ビルドへ更新してください。別PCでの実マルチ検証は引き続き必要です。

以前の1.3.2：不具合修正・バランス改善

• Redline：追跡・発見中にも予告付き突進を開始。床判定を実際の足元へ修正。遅延爆発は引き続き敵に無害です。
• Necromancer：召喚数・追跡速度・残留時間を調整。霊体は1回命中で消え、召喚物全体で命中間隔を共有。 床の手の減速は短時間にし、逃げたり武器で壊したりする余地を増やしました。デスヘッド装備中の強化は維持します。
• Deathlight：実際の飛行体に金色の輪と光を追従。天井巡回からも攻撃し、静止中も予告付き床攻撃を出します。床25・叩きつけ80へ強化。
• Chatterjaw：床の扇形と閉じる上下の歯で予告を明確化。75ダメージ・6秒間隔へ調整。
• Big Bang：自然出現の3体組全員が同じ抽選で変異。Snatcherは既定45→40へ微調整。 Belladonnaは床リングを残し、画面の文字表示だけを廃止しました。

1.3.2にはGluttonの被弾時返却・財宝保管・HP初期化の修正も含まれます。 既存の独自設定は維持し、Snatcher・Deathlightの旧既定値だけを一度移行します。

Gluttonの一時退場中も、敵全体が非アクティブになっても、飲み込んだ財宝の保管を維持します。 保管先もゲーム標準の安全な位置に統一し、地下へ隠した財宝がマップ外判定で破棄される問題を防ぎます。 ゲーム側のスタン・掴み処理で質量がリセットされても捕食による強化は残り、財宝返却時も一時的な質量変更を妨げず 元の強化分だけ解除します。参加者がホストになった際にGluttonが不意に全回復する問題も修正しました。 リワーク済み変異体は出現直後の攻撃前にHP初期化を済ませ、初回更新で受けたダメージが消えるのを防ぎます。 既存設定と被ダメージ後の4秒間の捕食停止は維持します。

別PCへの受信、財宝を保持した敵がいる状態での途中参加・実際のホスト交代・通常プレイのバランスは実マルチでの検証が必要です。 隔離した実ゲームの制御検査は、友人とのテストプレイを置き換えるものではありません。

Gluttonから財宝を取り戻す手段

実際にHPが減った攻撃1回につき、飲み込んだ財宝を1個だけ返します。その品で得たHP・接触威力・質量の 強化も解除します。被ダメージ後は既定で4秒間捕食を停止し、追加のダメージで残り時間を更新します。 返された品も同じ時間はほかのGluttonを含めて再捕食されず、短時間のダメージ保護が付きます。 撃破したときは残りをすべて返します。[Glutton] HurtEatCooldownSecondsで停止時間を調整できます。 既存の設定ファイルは削除不要です。 BerserkerEnemies Reborn側のソロ死亡処理で不足していた引数も互換処理で補い、Berserker化したGluttonでも 死亡・財宝返却が完了するようにしました。Berserkerの能力や設定は変更しません。

1.3.1 の新設定：1レベルの変異体数上限

[Mutation] MaxMutantsPerLevelで、そのレベル中に新たに変異する敵の総数を制限できます。 既定は6体で、5階ごとの確定抽選階とWesley追加敵にも適用します。既定設定の40階は 確定抽選階なので抽選確率は100%ですが、6体に達した後の敵は通常個体になります。 より易しくするなら数を下げ、以前どおり無制限にするなら0にしてください。

[Mutation]
MaxMutantsPerLevel = 3

同じ敵が再出現しても再計上しません。Tricksterの自然な4体組は4枠をまとめて使用し、 残り枠が4未満なら組全体を通常個体にします。Big Bangの自然な3体組は3枠をまとめて使用し、 残り枠が3未満なら組全体を通常個体にします。追加の小隊員は1体につき1枠を使用します。 値はホスト側で設定してください。参加者はローカル設定が異なっても、ロビー内では ホストの変異率・確定階・無効化リスト・上限を使用します。設定変更はロビー作成前に行ってください。

1.3.0 の主な変更

• Deathgaze・Poltergeist・Trickster・Redline・Resonance・Necromancer・Heartbreak・Deathlight・Parallaxを、 実空間の見た目と動きで判断する能力へリワーク。Deathgazeは閉眼中無敵、Redlineの遅延爆発は敵へのダメージ・吹き飛ばしなしです。
• Deadeyeは本物のPhoton Blasterのビーム全長判定、House Edgeは1.1.0の5色ルールへ変更。 Ricochetは反射性能を維持し、HUDを廃止しました。
• Tick の別変異 Power Leech を追加。半径14m内の装備スロットと地面にある電池付きアイテム全てから、 毎秒25％ずつ吸電します。水色の波紋で範囲を示し、離れるかTickをスタンさせれば止まります。
• Headman専用の Chatterjaw を追加。歯の音と高さのある弧で予告した後、前方130度を噛み払います。 しゃがむ・伏せる、予告範囲から離れる、遮蔽物に隠れる、スタンさせることで回避できます。
• Tricksterの崩壊後の復帰・攻撃確定順、ソロでのPoltergeistの物体選択、予告時間を変更したRedlineの突進時間を修正。 蔓・召喚物・茨の破壊判定は武器本来の壁判定・命中間隔に従い、茨の上部にも正しく当たる形状判定へ修正しました。 House Edgeの黒ルールは、プレイヤー自身のColliderで上方向の勢いが相殺されないよう修正しました。 また、敵生成直後の物理オブジェクト未準備な1フレームをネイティブの敵同士命中処理が無視し、 正常な命中は変えずに、まれなゲーム本体のHurtCollider例外を防ぐようにしました。
• 元の敵名を Faultline＝Trudge、Aftershock＝Loom、Parallax＝Shadow Child へ訂正しました。
• Wesley's Enemies 用に Hydroshock、Flashpoint、Scrambler、Crossfire、Barrage、Effigy の6変異を追加しました。 Wesley本体が実際に導入されている場合だけ登録されます。
• BerserkerEnemies Reborn互換を追加。変異後の名前もBerserker側が認識するため、同じ敵で変異能力と Berserker強化を同時に動かせます。
• 過去バージョンの説明欄にあった不具合・要望アンケートへのリンクを復元しました。
• 同期抽選と5階ごとのMutation Surgeは維持しています。

標準31種類の突然変異

1. Boomday Boy（Birthday Boy／橙）— 繰り返し近接爆発し、風船も接触地雷になります。死亡時も本体が爆発します。
2. Poltergeist（Mentalist／紫）— 最大3個の落下物に憑依し、射線を予告して突撃させます。50ダメージ、複数の物体で 0.8秒の命中間隔を共有。物がない部屋では霊体の物体を使用。掴む・本体をスタンさせることで妨害できます。 武器・カート・本物のデスヘッドは対象外です。
3. Meltdown Crew（Cleanup Crew／毒緑）— 低速・通常・高速追尾の爆弾頭3個を同時に投げます。
4. Snatcher（Hidden／紫）— プレイヤーを運び始めた瞬間、安全確認した別地点へ移動させ40ダメージを与えます。
5. Deathgaze（Peeper／赤）— 閉眼中は無敵。1.2秒の溜め後に開眼し、その瞬間に見えている目を直視していると60ダメージ。 視線を外すか壁に隠れ、開眼後3秒の隙に攻撃してください。露出メーターと強制的な視線誘導はありません。
6. Deadeye（Huntsman／青）— 毎射、本物のPhoton Blasterのビームを発射。威力・命中間隔・吹き飛ばしは同武器本来の処理です。 ビーム全長に触れた各プレイヤーに当たり判定があり、プレイヤーは貫通し、壁や固い物体で止まります。 旧仕様の「指定した1人だけに55を1回」は廃止しました。
7. Trickster（Gnome／紫）— 自然な4体組で変異し、各個体が近くの放置された財宝1個に紫の足を生やして逃がします。 最大6.5秒。財宝をつかむ・小人をスタン・倒すと解除。価値と重量はそのまま。タワー・飛びかかり・分裂はなく、地上攻撃50は維持。
8. Fenrir（Elsa／氷青）— 犬形態が3.5秒の溜め中に停止し、終了時に60ダメージの衝撃波と共に変身します。
9. Big Bang（Banger／桃）— 自然な3体組で抽選を共有し、全員が2倍サイズ・80ダメージの大型連鎖爆発へ変異。 3枠に満たない場合は組全体が通常個体です。設定で追加する小隊員も上限枠を使用します。
10. Glutton（Animal／琥珀）— 落ちている財宝を飲み込み、サイズに応じてHP・接触威力・質量が成長。倒すと保護された 財宝をすべて吐き戻します。ダメージを与えると飲み込んだ財宝を1個だけ返し、その品の分の強化も解除。 被ダメージ後は4秒間捕食できず、返された品もその間はほかのGluttonを含めて再捕食されません。
11. Alpha（Apex Predator／金）— 5秒後に別の敵と場所を交換して変身し、15秒間マップ全敵を獲物へ招集します。 単独時は財宝との交換、それも無ければ安全な床への再配置を使うため、能力が意図的に空振りしません。
12. Belladonna（Bella／マゼンタ）— ベルごとに0.9秒予告の床リングを放ちます。リングをジャンプしてください。 周囲の財宝は動かず、最大4個が時間差の水色リングで応答。空部屋でも本体リングは必ず出ます。文字HUDはありません。
13. Flambé（Chef／炎橙）— 転がるたび前後左右へ本物の起爆済みショップグレネードを4個投げます。敵には無害です。
14. Redline（Reaper／赤）— 1秒予告後、向きを固定して突進し、接触で60。終了2秒後に実際に通った幅3mの道が爆発し、 各プレイヤーへ75を1回だけ与えます。この爆発は、MOD追加分を含む敵にはダメージもノックバックも与えず、小物も壊しません。
15. Singularity（Bowtie／青紫）— 叫びがプレイヤーを引き込み、本物の財宝を重力軌道へ捕獲。終了時に高威力で射出します。
16. Faultline（Trudge／溶岩橙）— メイス攻撃が3方向の予告亀裂を残します。7.5秒残留し、接触中は40ダメージです。
17. Kaleidoscope（Clown／電気水色）— レーザー着地点から3色のプリズム刃を展開。予告後に120度回るため、刃を横切らず 隙間と一緒に周回してください。命中は40です。
18. House Edge（Gambit／カジノ金）— 1.1.0の5色ルールを復元。確定した出目を使います。赤＝0.8秒予告後の移動に55、 黄＝手持ち品を落として4秒間掴み禁止、緑＝周囲の敵を最大40回復＋6秒間40%耐性、白＝4連続打ち上げ、 黒＝安全確認したプレイヤー位置を順番に交換（1人なら吹き飛ばし）。対象範囲は色付きの輪で示し、SAFEポケット方式は廃止です。
19. Resonance（Upscream／共鳴青）— 1秒予告後、幅6mの音波を放ち、壁で1回反射します。往路と反射後にそれぞれ最大1回55。 動く波と反射先を見て避けてください。静止ルール・HUDメーターはありません。
20. Blood Bank（Tick／緑）— 吸ったHPを周囲の敵の回復・耐性へ分配。吸血完了後は6秒の「血の借金」が表示され、 放置で45ダメージ。そのTickをスタンまたは撃破すれば解除できます。
21. Railgun（Rugrat／充電水色）— 通常の財宝投げを高速の発光弾へ変え、バニラ物理衝突を9倍に強化します。
22. Blackout（Robe／黒紫）— 敵対中、16m内の室内灯・所持ライトをほぼ消灯し、追跡速度を1.75倍にします。複数範囲が 重なったライトは全てのBlackoutが離れるまで復元されません。
23. Contagion（Spewer／毒緑）— 嘔吐で最大3個の財宝を発光する掴み罠にし、さらに半径4m・8秒の胞子雲を残します。 目に見える緑の輪から出てください。2秒露出で50ダメージ、範囲外か固い遮蔽の裏では蓄積が2倍速で減ります。
24. Necromancer（Headgrab／魂紫）— 壊せる霊体の頭2体（命中20・1回で消滅）と床の手1個（16・0.8秒まで55%移動）を召喚。 1.5秒予告・6.5秒で消滅。召喚物全体で対象者ごとに1.2秒のダメージ間隔を共有します。召喚は11秒間隔です。 本物のデスヘッド装備中は3体・2個、9秒間隔へ強化し、頭自体は消費しません。最初の致死ダメージで3秒の蘇生儀式へ移り、 見える核を壊せば阻止、放置するとHP半分で1回だけ蘇生。死者がいなくても召喚は機能します。
25. Heartbreak（Heart Hugger／桃）— 予告した蔓を伸ばし、命中30＋引き寄せ＋噛みつき50。蔓の切断・遮蔽・本体スタンで解除。 対象の左右には壊せる茨を出し、接触中は毎秒20。抜け道は残します。相方合流HUD・心臓鎖・元のガス拘束は廃止です。
26. Deathlight（Oogly／黄）— 飛行体に金色の光と輪が付き、天井移動・静止中も光の床を残します。0.8秒予告後、4秒間・毎秒25。 天井巡回から射線固定の急降下へ移り、最初に触れた相手を捕獲。最大5mまで引き上げて80で叩きつけます。 低い天井では上昇を制限し、障害物・死亡・スタンで解除。 この拘束中だけ元のレスリングと落下ダメージの重複を抑えます。
27. Aftershock（Loom／電気紫）— 近くに見える相手がいれば、平手攻撃を待たず2枚の影壁で通路を挟みます。 最初の壁で止まり、画面テキストは出しません。壁が閉じる前に通路外へ避けてください。失敗で60・所持解除・吹き飛ばし。
28. Parallax（Shadow Child／水色）— テレポートの出発地点に残像を残し、6mの固定射線を1秒予告して65の一撃。 線の外へ避けてください。到着時・初回出現時には追加残像を作らず、HUD指示も使いません。
29. Ricochet（Huntsman別変異／琥珀）— 最大3反射・合計最大60m・対象ごとに1回60を維持。0.9秒予告はHUDではなく、 明滅して白くなる実空間の射線・音・反射点の光で表します。予告中に閉じた扉より先へは届きません。
30. Power Leech（Tick別変異／電気水色）— 半径14mの範囲で、装備スロット内や地面のものを含む 電池付きアイテム全てから毎秒25％吸電。スロット内は持ち主の位置で判定します。ゲーム本来の電池表示・ 保存残量にも反映されます。スタンまたは範囲外へ逃げれば停止し、使用キー自体は封じません。
31. Chatterjaw（Headman／牙赤）— 追跡中6秒ごとに、前方130度・最大8.5mの床範囲と閉じる上下の歯を1.5秒予告して75ダメージ。 しゃがむ・伏せる、範囲外や固い壁の裏へ逃げる、またはHeadmanをスタンさせて中断できます。 本来の近接噛みつきも残ります。

Wesley導入時の追加6変異

Magic_Wesley-Wesleys_Enemies が導入されている場合だけ有効です。必須依存ではないため、Wesley未導入環境では この6系統を抽選せず、REPO Mutant Enemies単体として通常どおり起動します。

1. Hydroshock（Gusher／水青）— 目に見える0.65秒の水圧溜めから、0.3秒間隔で3本の速い波を放ちます。 各波は0.6秒で12mへ到達し32ダメージ。初動を短縮、再発動は独立した4.5秒間隔。ジャンプか固い壁で回避。
2. Flashpoint（Roaster／炎橙）— プレイヤーの足元を記録し、縮むタイマー付きの燃焼円を設置。点火前に円外へ出てください。
3. Scrambler（Lost droid／信号緑）— 半径12mのEMPを溜め、露出したプレイヤーへ45ダメージと吹き飛ばし。範囲外か壁裏が安全です。
4. Crossfire（Lost Destroyer／深紅）— 対象地点へ直交する2本の射線を固定します。壁で切られた赤い2レーンから発射前に離れてください。
5. Barrage（Soldier／金）— 少しずつ角度の違う3本の照準線を予告し、順番に射撃します。1回の斉射による追加ダメージは最大1回です。
6. Effigy（Voodoo／呪紫）— 1人の開始位置を呪いの円として固定し、現在位置まで線で接続。時間内に半径7mの円外へ逃げてください。

抽選ルール

• 通常確率は 表示階 × ChancePerLevel（既定2.5%）で、MaxChance（既定25%）が上限です。
• GuaranteedSurgeInterval 階ごと（既定5）は抽選が100%ですが、MaxMutantsPerLevel（既定6体）の範囲内です。
• DisabledMutants は確定階でも有効です。Huntsman・Tickとも、片方だけを無効化すればもう片方、両方なら通常個体です。
• Wesley用変異も同じ同期抽選・確定階・HP倍率・DisabledMutantsの規則を使用します。
• 突然変異のHPは既定2倍、クリア階ごとに0.05倍増加し、3.5倍で止まります。
• 安定した Photon ViewID 抽選とホストから配信する変異設定により、クライアント間と再出現で同じ変異を維持します。

設定

BepInEx設定には、1レベルの変異体数上限・変異確率・確定階・HP倍率・オーラ・DisabledMutantsと、対応する攻撃の威力／範囲／時間があります。 Wesley用6変異の設定も、Wesley未導入時に害のない形で含まれます。

[Mutation]
DisabledMutants = Big Bang; Parallax
GuaranteedSurgeInterval = 5
MaxMutantsPerLevel = 6

上記の変異出現設定とリワークした攻撃の設定値はホストから同期します。それ以外の攻撃設定は揃えてください。 旧露出・鎖・撮影・経路再走用の設定は新能力には使いません。 既存の設定ファイルを削除する必要はありません。敵スポーン用キーはなく、Big Bangの能力による小隊生成だけを維持し、Tricksterの分裂は廃止しました。

導入と互換性

BepInEx、REPOLib 4.2.0以上、本パッケージをMod Managerで導入してください。手動では Matsu.MergedEnemyMod.dll をプロファイルの BepInEx/plugins 配下へ置きます。突然変異の決定、警告表示、プレイヤー所有端末での ダメージ解決を各クライアントが行うため、ロビー全員に同じビルドとゲームプレイ設定が必要です。

Wesley's Enemiesは任意依存です。導入する場合はロビー全員で揃えてください。実際のWesleyランタイム型まで確認してから 変異を付けるため、他MODの同名敵を誤って変更しません。

BerserkerEnemies Rebornも任意依存で、同時動作に対応しています。Berserkerのコントローラーを置換せず、 有効な敵名リストへ変異名を追加する方式です。同じ個体へ両方が付いた場合、バニラ側のHP・接触威力は後から設定するBerserker側が優先し、 独自攻撃の威力は本MODの設定を使います。変異能力・オーラ・予告表示はそのまま残ります。VoodooはBerserkerの「modded enemies」設定に含めます。

検証状況と注意点

この1.3.3投稿用パッケージに含まれるDLLは、製品ルールの回帰検査21,163件とゲーム／PUNのパッチ契約検査に合格。 隔離した実ゲームでは、任意敵MODなしで223/223件、Wesley 1.3.6＋Berserker Reborn 1.6.0併用の 15 FPS制限下（実測13.46 FPS）で260/260件に合格。両構成とも実行時エラー0件で、ZIPと同一DLLです。 修正した実空間の予告表示5枚を原寸で目視確認し、発動・カウントダウン文字の描画処理がないことを ソースと実行時の両方で検査しました。プレイヤー列挙に6人固定の上限はありません。 以前の1.3.2配布物と18,763件・208件・241件の検査証拠は、変更せず保持しています。

Changelog

1.3.4 — Updated playtest feedback and readable counterplay

• Trickster: strengthen its runaway-original-valuable curse to 12 seconds, 5.8 m/s, a 14 m loot search and five-second recast. Larger purple feet and a source link identify the culprit. Grab/stun/death stop it; price, mass and excluded item types are unchanged.
• Resonance: replace the ordinary reflected wave with three destructible tuning forks forming a shrinking triangle. A 1.5-second warning precedes five seconds of closing sound walls. The whole cage deals at most one configured hit per player; break any 20-HP fork to cancel all sides and stun Upscream. Check grounding, solid cover and swept boundary contact.
• Necromancer: alternate fixed skull lanes and floor hands instead of stacking homing heads with fresh snares. Two skulls / one hand normally, three / two with a stolen head, on seven-/six-second casts. At most one summon-damage hit per victim per volley. Keep the 1.5-second warning, breakable summons, brief slow and single interruptible revival.
• Deathlight: shorten the first dive delay and place wider, wall-clipped floor-light strips at a visible player's captured floor position. Stun cancels pending strips; floor/slam defaults remain 25/80. The gold body halo and physical lift/slam remain.
• Chatterjaw: replace the hard-to-read stance/sector test with one open jaw on the floor. After arming for 1.5 seconds, entry starts a 0.65-second closing tell and one 75-damage bite. Jump, leave the two-metre circle, break its central 20-HP molar, or interrupt Headman.
• Flashpoint: target from the actual optional-enemy body, not its stale parent spawn position. Capture the player's floor rather than a ceiling. Add a brighter ignition tell, a separate six-second cooldown and at least 1.25 seconds of warning. Cover and other floors are safe.
• Effigy: a visible doll, closing circle and reddening tether give at least four seconds to escape seven metres. Use an independent eight-second cooldown without overlapping curses. Anchor the growing doll and its arms at the captured floor so they cannot drift off-screen. Replace the native execution and attack slow/time-lock on Effigy only. Suppress native attack transitions/impulses and remove execution events from per-instance clip copies, avoiding old Wesley builds' obsolete damage-method reference. Ordinary Voodoo animations are not modified.
• Preserve custom configs, the host-controlled level cap and the survey link. No new required dependency, activation/countdown text overlay or keyboard spawn binding.

1.3.3 — Playtest fixes and no activation text overlays

• Remove Blood Bank's overhead debt text too; its native-world link now reddens, thickens and pulses faster before payment. Stun cancels it locally before payment, and an expired debt cannot hit twice.
• Rework Trickster into runaway valuables instead of another attack: purple walking feet, one unattended original valuable per Gnome, 6.5-second limit, grab/stun/death counterplay. No tower, pounce, cloning, price/mass changes or weapon/cart interference.
• Fix Kaleidoscope selecting the upper face of a low ceiling as its floor. Use the combatant's floor-height band, and cancel its prism immediately when the source is stunned, dies or despawns.
• Aftershock activates against a nearby visible player without requiring the slap animation. Keep the closing corridor, side escape and 60 damage; add cooldown and pending-trap cleanup.
• Hydroshock only casts at reachable nearby players, shows a water-pressure charge, starts sooner, uses faster waves and its own shorter cooldown. Default radius/damage increase 9/24 to 12/32 once; keep customized values. Swept hits include the terminal segment after a frame hitch.
• Remove every custom activation/countdown text overlay. Keep world-space tells, native game UI and mutant names. No extra required dependency; Wesley and Berserker remain optional.

1.3.2 — Glutton fixes and balance improvements

• Add Glutton counterplay and fix swallowed-loot retention, mass growth and HP initialization. Improve mutant balance and attack readability based on playtest feedback.

• Redline starts its warned charge during native pursuit/notice states, checks visible targets, and probes the actual Reaper feet rather than its raised torso. Its travelled-route explosion remains player-only: no enemy damage or knockback.

• Necromancer uses 2 skulls + 1 hand (3 + 2 with a stolen head), 11/9-second casts, a 1.5-second warning and a 6.5-second summon lifetime. Skulls hit once for 20 then dissipate; hands deal 16 once and slow movement to 55% for at most 0.8 seconds. All summons from one caster share a 1.2-second damage cooldown per victim. Breakable summons and the one-time revival remain.

• Deathlight can commit its warned dive from ceiling roam, paints a warned strip even when stationary, and has a gold halo/light following the physical flying body. Default floor/slam damage is 25/80; old defaults migrate once while customized values remain unchanged.

• Chatterjaw shows the entire floor sector and two closing rows of teeth. Its warning is 1.5 seconds, damage 75 and cast cooldown 6 seconds; crouch/crawl, cover and stun counterplay remain.

• Big Bang rolls its natural three-Banger group together and reserves three cap slots atomically. The entire group stays ordinary if fewer than three slots remain. Summoned top-ups still cost a slot each.

• Snatcher default damage reduced slightly from 45 to 40, with a one-time old-default migration. Belladonna retains its floor waves but no longer draws a text HUD. Other tested, appropriate kits stay unchanged.

• Keep swallowed valuables deactivated independently of their Glutton, so temporary component or whole-rig despawns no longer expire the stash timer and lose the original loot.

• Use the game's safe storage position instead of a below-map teleport that could trigger native valuable destruction, particularly when re-enabling an already full Glutton.

• Apply meal mass growth to the native permanent baseline as well as the current body. Native mass resets preserve growth; returning loot during an override changes only the underlying baseline.

• Mark Glutton's initial HP setup on guests too, preventing an unintended refill on promotion to host.

• Initialize reworked-mutant HP before native damage is accepted, preventing the first update from restoring damage taken in the spawn frame. No change to ordinary healing or respawn rules.

• Each hit that actually reduces a living Glutton's HP now returns one swallowed valuable. The original valuable is released, with brief damage protection; no replacement loot is spawned.

• Damage pauses eating for 4 seconds by default. Repeated damaging hits restart the pause, including when its belly is empty. Returned loot cannot be swallowed by any Glutton during that window. Added [Glutton] HurtEatCooldownSeconds (0.5–60 seconds).

• Returning a valuable removes the exact health, contact-damage and mass growth it originally granted. Re-swallowing therefore cannot accumulate duplicate growth from the same meal. Growth amounts and their removal are sent by the host to all peers.

• Zero damage and fully resisted hits do not trigger a drop. Lethal hits retain the full-haul death return, and ordinary despawns still retain swallowed loot until respawn.

• Fixed Glutton's death-event ordering so native Animal despawns cannot skip the remaining loot return or leave a stale kill flag. Loot returned on death also receives re-eating protection.

• BerserkerEnemies Reborn's solo despawn reflection call now supplies the game's optional Photon sender metadata. This prevents its argument-count exception from blocking a Berserker Glutton's death and loot return; Berserker abilities and settings are unchanged.

1.3.1 — configurable mutants per level

• Added [Mutation] MaxMutantsPerLevel (default 6, 0 for unlimited) in response to feedback that fifth-level surges become overwhelming in deep runs such as level 40. The cap applies to all built-in and optional Wesley variants even when the surge roll is 100%.
• Counts distinct mutated enemy bodies admitted during the level. Respawns keep their identity without taking another slot; Trickster's natural quartet reserves four together, and Big Bang squad members consume remaining slots. A fresh game resets the budget even if it starts at the same displayed level number.
• The host now publishes the mutation-generation settings (chance, surge interval, disabled list and level cap) as room properties. Guests wait for those settings and use them even when their local values differ; settings are fixed for the room, so change them before creating a lobby. Other non-synchronized attack settings still need to match. The survey link remains in both descriptions.

1.3.0 — approved reworks, Wesley mutations and Berserker compatibility

• Added Chatterjaw for Headman, a separate family from Faultline's Trudge. Its mouth marks a fixed high 130-degree sector for 1.3 seconds, then deals 65 damage to standing players. Crouching, crawling, leaving the arc, solid cover or stunning Headman avoids the attack; native bites remain.

• Completed a GPU image audit of the HUD-free warnings. Resonance now previews the complete outbound and reflected route instead of only its origin, and Parallax uses a guaranteed-visible cyan humanoid echo, white outline and arrow rather than depending on Shadow Child's temporarily disabled teleport renderer.

• Added Power Leech, a mutually exclusive second Tick mutation alongside Blood Bank. Its 14 m cyan aura drains 25 battery percentage points per second from every in-range battery-powered item: equipped slots use their owner's position, loose items use their own. The host calls the game's native ItemBattery.Drain, retaining native charge-bar updates, saved charge and multiplayer synchronization. Stun or leave the radius to interrupt it. Both Tick variants respect DisabledMutants; the original Tick mutation roll remains unchanged. Tick's Berserker alias also includes the new name.

• Follow-up fixes: Trickster initializes a valid recovery destination on collapse and commits its strike from the host only after interrupt checks. Poltergeist can select loose objects without Photon IDs in solo. Redline's 1.5-second charge is independent of warning duration and caps its final physics step.

• Native enemy hurt processing now skips only the transient spawn frame where an enemy rigidbody exists before its physics object or enemy reference is ready. Valid native hits still use the original method; the guard prevents the intermittent base-game HurtCollider.EnemyHurtRigidbody null exception.

• Destructible vines/summons/thorns use native weapon wall checks and cooldowns. Thorn hits use their raised box shape, and a destroyed target cannot run its break callback twice. Authority is read live; received effect IDs advance local counters so a promoted host cannot reuse existing IDs. Promotion no longer reruns the mutation's initial full-health assignment (full host-migration playtest pending).

• Reworked Deathgaze into an invulnerable closed-eye wind-up, a 60-damage opening gaze flash and a three-second vulnerable open interval. Removed the exposure HUD, repeat-burn meter and forced gaze.

• Poltergeist possesses up to three loose objects and rams warned lanes (50 damage, shared 0.8-second hit interval). No eligible objects: spectral rams. Grabbing the object or stunning the source interrupts it.

• Trickster stacks its existing natural Gnome group into a breakable tower (75 strike / 50 ground attack). Base damage, grabbing or stun collapses it. Ceiling clearance is checked during assembly and movement. Removed disguises, death splits and split-child spawning; reforming does not refill health.

• Redline commits to a warned charge (60), then its real route explodes after two seconds (75 once per player). Damage and impulse explicitly target players only. Explosion visuals disable all native hurt colliders before activation: no enemy damage, enemy knockback, prop damage or prop impulse.

• Resonance previews and sends a broad travelling wave (55 per leg) with one wall reflection instead of the stillness test. Necromancer combines destructible skulls, grasping floor hands, stolen-head empowerment and one interruptible three-second half-health revival. Real death heads are released, never consumed.

• Heartbreak combines a cuttable pulling vine (30 catch / 50 bite) with breakable side thorns (20/sec). Removed partner-chain HUD and native gas capture. Deathlight combines ceiling light trails (20/sec), a fixed dive, a clearance-capped carry and 70-damage slam. Tumble readiness, both bodies' swept movement, low ceilings and interrupted/disconnected victims are checked; carry overrides expire automatically.

• Parallax now leaves a bright humanoid departure afterimage and a one-second-warned linear strike (65). Initial spawn and arrival do not produce an extra echo. Ricochet retains its three-reflection 60-damage kit and replaces its HUD with a pulsing world path, reflection flashes and sound.

• Deadeye creates the actual Photon Blaster beam for every shot and keeps native damage/cooldown/force fields. Its full length can hit all contacted players, stopping at scenery/solid loot. Removed the old target-only 55-damage substitute and Clown/line-only fallback.

• Restored House Edge's 1.1.0 rules: red movement restriction, yellow forced drop/grab lock, green enemy healing/resistance, white repeated launch, black safe cyclic position swap (solo impulse). The settled roulette angle selects the rule; host rule values are synchronized. The SAFE-pocket HUD is gone. The solo black rule now derives its horizontal push from Gambit instead of a floor-ray point, preventing the player's own collider from cancelling most of the intended upward launch.

• Corrected base-enemy documentation and Berserker aliases: Faultline = Trudge, Aftershock = Loom, Parallax = Shadow Child (internal EnemyThinMan). Headman no longer incorrectly enables Faultline.

• Rework events validate their host sender, use monotonically increasing serials and carry exact paths, target IDs, network time and a validated 22-value host-rule snapshot. Retired config keys for replaced mechanics are no longer bound; users do not need to delete their existing configuration.

• Added six optional mutations, one for every currently registered Wesley's Enemies character:

  • Hydroshock (Gusher): three expanding, jumpable pressure waves with swept collision and wall cover.
  • Flashpoint (Roaster): a warned burn zone fixed to the target's captured floor position.
  • Scrambler (Lost droid): a cover-blocked EMP that damages and throws exposed players.
  • Crossfire (Lost Destroyer): two perpendicular, wall-clipped firing lanes.
  • Barrage (Soldier): three warned firing lanes that resolve in sequence and cap at one mutation hit.
  • Effigy (Voodoo): a tethered curse broken by escaping the captured seven-metre circle.

• Wesley integration is a true soft dependency. A family is eligible only when the Wesley plugin is loaded, its exact runtime behaviour component is present, and its base enemy name matches. Other mods' similarly named enemies are ignored, and this package keeps no assembly reference to WesleysEnemies.dll.

• Added BerserkerEnemies Reborn 1.6.0 compatibility. Its enabled base names now expand to the renamed mutant names, allowing one enemy to retain both the mutation component and Berserker controller. The accidentally omitted Hidden toggle is repaired, and Voodoo participates under containModded.

• Berserker remains authoritative for its final health/damage settings when both modifiers select the same enemy; mutation attacks, aura and warnings remain active.

• Restored the public bug-report/request survey link in both the English and Japanese package description.

• Release compilation passes with zero warnings/errors. The linked production-helper suite passes 18,733 assertions. The real Wesley 1.3.6 and Berserker Reborn 1.6.0 assemblies load together; the compiled compatibility postfix verifies 18 representative aliases, including both Tick variants and Headman/Chatterjaw, with zero hard optional-mod references. Sixteen disabled-family/absent-Wesley checks pass. Game/PUN reflection checks verify 25 reflected fields, four private call targets, 12 inherited RPC receivers plus the Power Leech pulse, and 23 Harmony target signatures.

• Isolated Unity 2022.3.67f2 probes for the final production DLL pass in all four optional-mod layouts: no optional mods 176/176 in non-batch Direct3D 11 with five inspected GPU captures, Wesley only 205/205, Berserker only 177/177, and both 208/208 in non-batch Direct3D 11 under a test-enforced 15 FPS cadence (14.730 FPS measured), with zero MOD runtime errors and zero rendering errors in the rendered runs. All 31 built-in mutations attach through their real native prefab path in every layout. The production player-list and radius helpers also return all 12 supplied entries without a six-player cap. The probes exercise real enemy prefabs and player HP for all selected reworks, three simultaneous real battery items for Power Leech, Necromancer's normal and equipped-head summon limits, native weapon destruction, one-time revival, Chatterjaw's standing/duck/cover/cancel cases, the five House Edge rules, the native hurt-initialization guard, and all six Wesley attacks (including Scrambler cover and Effigy escape). A final-DLL Steam-authenticated Photon run passes 26/26 checks with RoboUnion 0.6.2 in a real private room with MaxPlayers = 12, including Headman SpawnRPC, deterministic Chatterjaw attach, inherited attack RPC, one owner-local 65-damage hit and pending-warning cleanup on room leave. Ozoka Gaming MorePlayers 1.1.0 separately passes the same 12-slot gameplay path at 22/22; both lobby mods remain optional. This confirms a 12-slot host path, not seven simultaneous distinct-account peers; a live host/guest, actual seven-player and full balance pass remain. The legacy zelofi-MorePlayers-1.0.5 package is not compatible with the current game itself: its startup patch references the removed NetworkConnect.instance field, so it fails before a room can be joined. The final rendered runs include Resonance's complete warning route and reflected return, Parallax's humanoid echo, Ricochet's three bounces, Redline's delayed route, Chatterjaw, every Wesley attack and the native Photon Blaster beam. Audio mix and combat balance remain live-play judgements. The final-DLL authenticated host-leave portion holds a Chatterjaw warning 30 seconds beyond its normal expiry, then confirms Photon teardown removes it with no pending local damage object. The final 176/176 no-optional graphics run includes a native singleplayer level transition: a warning held 60 seconds ahead is removed by RunManager.ChangeLevel, and no detached mutation effect survives. A separate native solo GAME OVER/new-run reset passed 176/176 checks and removed a pending Chatterjaw bite. With Wesley and Berserker installed, a controlled Direct3D 11 stress run kept all 37 mutation variants and 43 native enemy parents active for ten seconds: 211/211 checks, zero runtime/render errors, and 137.776 FPS on the test RTX 3060 Ti. Native AI movement was paused after attachment; this is not a 43-enemy combat or RPC benchmark. A live Headman component passed a synchronous simulated guest-to-host transition at 180/180 checks: wounded HP stayed at 37/500, the next event serial became 41 after receiving 40, and the temporary test authority override was removed. Distinct-account migration remains untested. The release number remains 1.3.0; no automatic upload is performed.

1.2.0 — major uniqueness and reliability update

• Added Ricochet, a mutually exclusive Huntsman alternative: up to three wall reflections, a fixed 0.9-second warning path, closing-door recheck, and one 60-damage hit per caught player.
• Replaced Parallax's rarely triggered portal pair with reliable targeted severance. Each Thin Man arrival fixes a cyan cut and perpendicular magenta cut onto a visible living player's position; they fire after 1.2 seconds and another 0.8 seconds for 55 each. Unsafe player/loot portal transport is gone.
• Separated mechanics that had copied another mutant's job:
  • Poltergeist no longer aims or throws valuables. It owns the vertical gravity cycle: local-player zero-G lift, a white inversion warning, high-G force, and a 25-damage slam for anyone still in its field.
  • Deathgaze no longer fires a second generic laser. Looking at the eye fills a visible exposure meter; looking away drains it, and an uninterrupted stare accelerates repeat 50-damage burns.
  • Belladonna no longer orbits or shoots valuables. Every bell always creates a jumpable primary floor wave; nearby valuables remain fixed and answer with staggered cyan echo waves.
  • Kaleidoscope replaces three static blast marks with three rotating prism blades. Players move with the gaps through one 120-degree sweep; swept-angle collision covers long frames.
  • House Edge replaces five unrelated colour rules with one readable roulette game. Five pockets spin, the winning colour is labelled SAFE, and same-room marked players must enter it before settlement.
• Necromancer now casts on visible living players every 12 seconds even before a death. Its counter is the inverse of Heartbreak: run beyond the 20 m range and hold until the soul chain turns white and snaps. Added an owner-only RUN AWAY / HOLD DISTANCE countdown and host validation for the cast RPC.
• Alpha retains enemy swapping and its global hunt, but a lone Alpha now swaps with loose loot or moves to a verified floor point instead of spending its countdown on an intentionally empty transformation.
• Contagion retains infected loot and now always leaves a warned spore field: 4 m radius, eight-second active life, and 50 damage per two seconds of exposure. Cover and retreat drain exposure twice as fast.
• Blood Bank retains ally healing/resistance and adds a visible 45-damage blood debt six seconds after feeding. Stun or kill that Tick to cancel the debt, so the mutant remains meaningful without allies.
• Heartbreak uses host-selected stable pairs, host-controlled pulses/resolution, and a complete NavMesh path plus travel-budget check for the solo phantom-heart objective.
• Deadeye now has a functional LineRenderer and the same explicit 55-damage cover test even when neither Photon Blaster nor Clown laser material can be loaded. Disabled/dead targets and stale beams are cleaned up.
• Redline checks every route segment crossed during a frame, preventing low-frame-rate tunnelling. Belladonna's rings and Kaleidoscope's blades use equivalent swept collision helpers.
• House Edge ignores players behind solid room boundaries and points the winning pocket toward the nearest visible participant. Its orbit radius now makes that participant's starting point part of the final safe ring, preventing an objective from being selected on an unreachable side of a narrow room.
• Added owner-readable countdowns for Heartbreak, Deathlight, Aftershock, Contagion, Parallax and Ricochet, plus Resonance's stillness state. Twelve central warnings use stable HUD lanes instead of overwriting one another during a mutation surge.
• Room-scale selection and damage now respect solid cover for Heartbreak, Resonance, Faultline and Aftershock. Necromancer and Aftershock ignore their own rig while testing visibility, fixing false self-blocking; the latter also clips its corridor at the first real wall and refuses to attack unseen players.
• Fully draining Deathgaze now clears hidden repeat acceleration, real walls break mutual gaze, and a missing first-person camera can no longer charge an invisible rule.
• Secured all 32 custom gameplay RPCs with sender metadata and current-host validation. Spawn and Thin Man Harmony postfixes mirror vanilla RPC authorization so rejected guest messages cannot trigger mod effects.
• Fixed Boomday balloon replacement/cleanup calls being mistaken for real pops, which could broadcast one explosion per peer. Only a genuine host-observed pop now detonates.
• Big Bang squad positions are announced before spawning and consumed on every peer, so a summoned squadmate is the same pink-aura mutant everywhere instead of becoming a normal guest-side Banger. PackSize is clamped to 1–12, and squad creation fails closed if the leader has no PhotonView.
• Belladonna's native contact-damage upgrade now applies on every peer, allowing REPO's victim-authoritative collider to deal the intended 60 to guest-owned players.
• Reused aura and Blackout work buffers to reduce repeated allocations while preserving their existing kits.
• Removed every keyboard spawn shortcut, its 29 configuration bindings, both input paths, forced-spawn helper, dedicated network event, and marker. Gameplay-created Trickster children and Big Bang squadmates remain.
• Displayed levels 5, 10, 15, ... still guarantee every enabled supported mutation. Strong established values were not reduced. All lobby members must use this same build.
• Release compilation and 6,518 live-helper geometry/director/timing assertions pass. Package layout, binary identity, removed-feature scans, and hashes are checked during release packaging. Solo/multiplayer gameplay and performance still require an in-game validation pass; this changelog does not claim otherwise.

1.1.0

• Strength-only 28-mutant normalization:
  • No mutation was reduced below its original 1.1.0 threat. Mutant health remains 2.0x + 0.05x/level with a 3.5x cap; Big Bang remains 80 damage, Meltdown heads remain 75, Trickster remains 50, Belladonna remains 60, and Glutton keeps its original full growth.
  • Weaker direct specials were raised toward the established high-threat group: Deadeye 40→55, Fenrir 45→60, Redline 42→55, Faultline 32→40, Kaleidoscope 28→40, House Edge 40→55, Resonance 45→55 and Contagion 35→50.
  • Poltergeist now has an 11-metre field, faster throws, stronger gravity and a new 25-damage impact at the end of each inversion. Snatcher now deals 45 on relocation; Alpha's full-map hunt lasts 15 seconds.
  • Physical/support kits were raised rather than reduced: Singularity reaches 10 metres with 8x debris impact, Blood Bank heals up to 25 with 45% resistance, Railgun uses 9x impact, and Blackout expands to 16 metres with 1.75x pursuit speed.
  • The five newest mutants were raised: Necromancer 50, Heartbreak 10-per-pulse/50 snap, Deathlight 50, Aftershock 60 and Parallax 25, alongside stronger range, pull, duration or activation pressure.
  • Balance revision 2 recognizes both original and temporarily lowered defaults and moves them to this stronger preset automatically, while preserving manually customized config values.
• Large mutation rework:
  • Levels 5, 10, 15, ... are now guaranteed mutation surges: every enabled supported enemy mutates. GuaranteedSurgeInterval controls the interval and DisabledMutants remains respected.
  • Trickster now rolls once per vanilla four-Gnome group, so all four mutate together. A killed Trickster splits into two real networked Gnomes once per life; children cannot split again, and a genuine respawn resets the entitlement.
  • Deadeye no longer relies on the Photon Blaster prefab's visual/internal collider. An unobstructed beam now applies one explicit victim-authoritative line hit, so it cannot be visual-only.
  • Poltergeist has stronger default range, lift and throw cadence, plus a periodic high-gravity inversion that slams players and floating objects back down.
  • Belladonna replaces unreliable phantom decoys with cursed cargo: her bell pulls nearby real valuables into orbit and launches them at the target with boosted physical impact damage.
  • Redline (mutated Reaper) — records its overclocked chase route, then sends a lethal moving pulse back through that exact path.
  • Singularity (mutated Bowtie) — captures real valuables in orbit during its gravity-well yell, then slingshots every captured object at players when the yell ends.
  • Faultline (mutated Trudge; earlier text incorrectly said Headman) — every mace attack leaves a persistent three-branch floor fracture; after warning, all branches remain dangerous for several seconds.
  • House Edge (mutated Gambit) — roulette colours now invoke distinct house rules: Red Light, loot confiscation, enemy insurance, player launches, or a position shuffle.
  • Resonance (mutated Upscream) — marks nearby players with a returning echo; players must stop moving before it returns or take explicit damage.
  • Contagion (mutated Spewer) — puke infects nearby loose valuables. Infected loot visibly glows and triggers a one-shot toxic backlash when grabbed.
• Five additional mutants — 28 total:
  • Necromancer (mutated Head Grabber) — a stolen death head soul-chains exposed players; sustained cover severs the chain, while failure disarms and recalls the victim toward the head.
  • Heartbreak (mutated Heart Hugger) — forges paired player chains that require a held reunion to break, with a phantom-heart objective for an unpaired player.
  • Deathlight (mutated Oogly) — photographs players in its hostile spotlight; cover erases the image, while failure rewinds the victim to the captured position.
  • Aftershock (mutated Shadow Child) — each slap closes two giant shadow walls around a corridor; players must escape laterally before the final clap catches, disarms and throws them.
  • Parallax (mutated Thin Man) — every teleport creates temporary two-way gates that transport and launch both players and loose physics objects between the exact endpoints.
• Snatcher keeps its instant safe-map teleport and initial damage, but its delayed destination bomb has been removed.
• Unchanged by request: Boomday Boy, Meltdown Crew, Kaleidoscope, Blood Bank, Railgun and Blackout retain their 1.0.0 abilities and tuning. Other mutations not listed above also keep their existing kits.
• Added tuning sections and host debug keys for Contagion and all five additional mutants.

1.0.0

• Nine brand-new mutants — 22 total:
  • Redline (mutated Reaper) — an overclocked pursuit that leaves explosive wakes along its route.
  • Singularity (mutated Bowtie) — its yell creates a gravity well followed by a final implosion.
  • Faultline (mutated Trudge; earlier text incorrectly said Headman) — mace attacks trigger a telegraphed chain of four floor eruptions.
  • Kaleidoscope (mutated Clown) — its laser impact splits into three delayed floor detonations.
  • House Edge (mutated Gambit) — its roulette creates an explosive clockwise ring.
  • Resonance (mutated Upscream) — attacks leave delayed echoes at players' recent positions.
  • Blood Bank (mutated Tick) — bites convert stolen health into healing pulses for nearby enemies.
  • Railgun (mutated Rugrat) — thrown valuables gain extra speed, impact damage and a projectile trail.
  • Blackout (mutated Robe) — suppresses nearby room and carried lights while hunting.
• Threat escalation pass for five weaker mutants:
  • Snatcher gained an unstable destination rift and 25 initial teleport damage.
  • Deathgaze fires sooner, hits harder and accelerates repeated beams during an uninterrupted stare.
  • Fenrir transforms sooner and releases an enemy-safe shockwave when its countdown reaches zero.
  • Blood Bank also grants nearby enemies temporary damage resistance.
  • Blackout gains a configurable pursuit-speed boost while its darkness field is active.
• Late-run threat scaling: mutant health gains a configurable bonus per completed level and respects a configurable maximum multiplier.
• Added Mutation / DisabledMutants, allowing individual mutations to be disabled without removing the mod.
• Gave each mutation type an independent deterministic roll salt so all clients agree without species sharing equivalent ViewID roll streams.
• Removed obsolete pity-state scaffolding and made per-level sticky mutation state explicit per mutant type.
• Added tuning sections and host debug keys for the nine new mutants, plus the new threat-scaling options.

0.10.0

• Hivemind is gone — meet the Trickster (mutated Gnome). The population-doubling Hivemind could lag the game badly, so the Gnome mutation was redesigned: the Trickster is a MIMIC — it disguises itself as a random valuable and ambushes whoever comes to collect it.
• Five brand-new mutants:
  • Big Bang (mutated Banger) — twice the size, roams in a squad of five, and detonates with the full shop-grenade blast. One going off tends to set off the rest.
  • Glutton (mutated Animal) — swallows any loose valuable it gets close to, and every meal makes it tougher, harder-hitting and heavier (bigger valuables feed it more). Kill it to get your haul back.
  • Alpha (mutated Apex Predator) — freezes with a countdown before transforming; at zero it trades places with a random other enemy on the map, then howls — every enemy hunts its prey for a while. Works for provoked/touched transformations too.
  • Belladonna (mutated Bella) — her bell-ring attack tell summons a swarm of identical phantom decoy tricycles that charge in alongside her. Same look, same sound — the real one hits hardest, but a decoy still costs you. She also escalates to her bell/attack sequence far faster than vanilla and holds a grudge much longer once provoked.
  • Flambé (mutated Chef) — flings four real, armed shop grenades around itself each tumble attack. Its grenades can't hurt enemies — only players.
• New config sections: Trickster, BigBang, Glutton, Alpha, Belladonna, Flambe (the old Hivemind section is gone). New debug spawn keys: F3 / F1 / F11 / F12 / Insert.
• Post-release polish pass: silenced the Trickster's disguise (its own footsteps/idle sounds no longer give it away); fixed Big Bang's squad occasionally summoning far more than its configured size when multiple mutants rolled near each other; fixed the Alpha sometimes showing its post-transform model/animation years before its countdown actually finished; Glutton's growth from eaten valuables now correctly resets when it's actually killed (a mere despawn still preserves it).
• Full self-audit: reviewed every mutation and Harmony patch for host/client desync bugs. Fixed one narrow edge case — a Flambé grenade's fuse time could go out of sync between the host and clients if Flambe/GrenadeFuseSeconds was changed away from its default, causing an occasional client-side double detonation effect. Everything else checked out: mutation rolls are correctly deterministic across every client, all damage/knockback correctly reaches every player, and no other host-only gaps were found.

0.9.3

• Fixed: Boomday Boy balloons not exploding when physically touched/punched. Vanilla's own balloon pop handler (CheckForPoppedBalloons → RemoveBalloon) runs before our distance-based check, silently removing the balloon before the explosion could trigger. Now intercepted via a Harmony Prefix on RemoveBalloon: any Boomday Boy balloon that gets popped also detonates.

0.9.2

• Fixed: Mutation aura/glow only visible on host. The mutation component was attached during EnemyParent.Spawn when Photon ViewID is still 0, causing the deterministic roll to disagree between clients — only the host's copy would mutate. Fixed by switching to SpawnRPC which fires after ViewID is assigned, so all clients always agree.
• Fixed: Deadeye (mutated Huntsman) Photon Blaster beam dealt no damage to non-host players. The beam's HurtCollider was incorrectly disabled on non-host clients. REPO's damage system is victim-authoritative (IsMine check inside HurtCollider.PlayerHurt) — each client must have its own active collider to register damage on its own player. Restored for all clients. Also fixed: beam could stop firing permanently after the first shot (_activeBeam null-check bug).
• Fixed: Boomday Boy explosions (proximity blast, death blast, balloon chain, balloon contact) dealt no damage to non-host players. All four explosion paths now broadcast via [PunRPC] on the enemy's PhotonView so every client spawns the explosion locally. Victim-authoritative HurtCollider prevents double damage automatically.
• Confirmed: Fenrir countdown display runs on every client independently (state is RPC-synced by vanilla EnemyElsa). No fix needed.
• Confirmed: Meltdown Crew 3 heads fully synced — extra heads are Photon network objects (SpawnNetworkPrefab) and their explosions use [PunRPC] ExplodeRPC. No fix needed.
• Stronger mutation auras — default glow intensity 4.5 → 12, light range 3.7 m → 6 m. Adjustable in BepInEx config.

0.9.1

• Fixed mutations happening far too often — enemies could all end up mutated even on early levels, ignoring the configured chance. Mutation odds now work as intended.
• New MaxChance cap (default 25% per enemy type) so the per-level scaling can't run away to a near-guaranteed mutation on deep runs. Raise it to 1 for the old behaviour, or lower it to make mutants rarer.

0.9.0

• Three new mutants:
  • Deadeye (mutated Huntsman) — shoots the players' own Photon Blaster: a sustained laser beam.
  • Hivemind (mutated Gnome) — multiplies over time. One gnome becomes two, becomes four...
  • Fenrir (mutated Elsa) — the dog freezes and a countdown appears over its head when it spots you; when it hits zero it transforms and hunts as normal. Just enough time to run. Petting won't save you.
• Mutants now show their name when you grab one (e.g. "Fenrir", "Boomday Boy").
• Mutation chance reworked: now a flat 2.5% per level with no upper cap (was 1% + a pity system), so deeper runs get much wilder.
• Brighter auras — mutants now glow more strongly so they're easier to spot.
• Fix: Deathgaze's beam no longer gets blocked when the Peeper is mounted on the ceiling.

0.8.0

• Auras are now actually visible — the coloured mutation aura is a proper light now, so you can spot a mutant at a glance (even the otherwise-invisible Snatcher).
• Meltdown Crew now lobs three heads at once (normal / sluggish / frantic speed) instead of one at a time — fully synced for everyone.
• Poltergeist — its zero-gravity field range is now shown, its thrown objects hurt players properly again, and it no longer damages/stuns itself with its own throws. Field range trimmed a little.
• Boomday Boy — its blasts deal damage again, no longer knock/hurt itself, and it turns hostile and chases you after it goes off.
• Deathgaze stare time increased a bit, and its beam no longer gets blocked by the Peeper itself.

0.7.0

• New mutant: Deathgaze (mutated Peeper). Don't let it hold you in its stare for too long.

0.6.0

• Two new mutants:
  • Meltdown Crew (mutated Cleanup Crew, toxic-green aura): instead of lobbing one bomb-head, it fires a 3-shot volley — normal speed, then a sluggish half-speed head, then a frantic double-speed head.
  • Snatcher (mutated Hidden, violet aura): instead of slowly dragging a grabbed player far away on foot, it instantly teleports them to a random spot on the map (verified to be solid ground, never a pit) and hurts them the moment it grabs.
• Mutation chance reworked into a pity system: chance is now level% + pity, where pity grows by that level's own level% for every level a given mutation type fails to appear, and resets to 0 the moment it does — so a long dry streak makes the next appearance increasingly likely, independently per mutant type.
• Sticky per-individual mutation: once a specific enemy mutates, it stays mutated through every despawn/respawn cycle within the same level (previously it could theoretically re-roll). Verified this also works correctly with two enemies of the same type alive at once, one mutated and one not.
• New jacket artwork.

0.5.0

• Everyone must install: mutation attachment now happens independently on every client (a deterministic per-enemy roll), so mutation auras and visuals render correctly for all players, not just the host.
• Mutation auras recolored: replaced the point-light aura with a Fresnel rim-glow on the enemy's own model (Boomday Boy = orange, Poltergeist = light blue), visible to every client.
• Real explosions: Boomday Boy's blasts now use the game's actual explosion (damage, knockback, and sound), replacing the old fixed-damage/VFX-only approach.
• Balloon rules overhauled:
  • A player touching a balloon now explodes only that single balloon — no more chain reaction on touch.
  • An enemy touching a balloon just pops it harmlessly.
  • Death/recurring-blast chain reactions now detonate balloons in the order they were placed, one every 0.1 seconds, and this fix also makes the touch-explosion actually trigger reliably.
  • Multiple Boomday Boys now correctly track only their own balloons.
• Slightly reduced Boomday Boy's explosion damage.
• Poltergeist rework: removed the indiscriminate telekinetic damage entirely. Thrown valuables now use the same throw physics as the game's own loot-throwing enemy — the object's own impact deals the damage, so there's no more artificial or unavoidable hit.
• Mutant health multiplier (2x by default) now reliably applies to the enemy's current health, not just its maximum.

0.4.2

• Rebalanced Boomday Boy explosion damage and mutation chance scaling (level x 1% by default).

0.4.0

• Added Poltergeist (mutated Mentalist): persistent zero-G field + telekinetic barrage.

0.1.0

• Initial release. Boomday Boy (mutated Birthday Boy): recurring bomber with chain-exploding balloons.
