Risk of Deadlock

Play Risk of Rain 2 as Haze, Abrams, Seven, Infernus, Mo & Krill, Viscous, Rat King or Billy from Deadlock, with their real models, animations, guns, abilities, icons and voices.

You need Deadlock installed

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6819 (v1.0.0, 2026-10-25). Nothing from Deadlock is in this download. The heroes are read from your own Deadlock install (free on Steam):

1. Install Deadlock on Steam (you never need to open it).
2. Install this mod with r2modman (or the Thunderstore Mod Manager) and click Start modded.
3. On the first start, pick your heroes: a window lists them with the time each takes (all eight: about 2 minutes). Press Go and the loading screen shows each one being read from Deadlock. It isn't stuck. Later starts are normal; heroes you skipped come back in that window, and a Deadlock update re-reads them by itself. Playing online? Every player needs the same heroes installed: install all of them to join any game.

Installing by hand, or something went wrong? The step-by-step guide is INSTALL.md. In short:

• "Deadlock was not found": set Deadlock folder in the mod's config (r2modman: Config editor → melty.deadlockofrain) to your Deadlock folder, e.g. D:\SteamLibrary\steamapps\common\Deadlock (Steam → Deadlock → Manage → Browse local files).
• "DeadlockExtract.exe is missing" or reading never ends: your antivirus removed or blocked the mod's Deadlock reader (see About DeadlockExtract.exe below). Restore or allow it, then restart.
• Every step is written to BepInEx/LogOutput.log (r2modman: Settings → Browse profile folder). Post it in the Discord.

Hero pages

Every hero's abilities, numbers and measured damage next to their Risk of Rain 2 match:

• Haze (Commando) · Abrams (Loader) · Seven (Artificer) · Infernus (Engineer)
• Mo & Krill (MUL-T) · Viscous (REX) · Rat King (Captain) · Billy (Mercenary)
• Balance overview

Features

• Eight new survivors, each with Risk of Rain 2's four skills built from their Deadlock kit, plus their ultimate as equipment:
  • Left Click: their Deadlock gun, with its magazine and reload (the rounds show above the skill bar).
  • Right Click and Shift: two Deadlock abilities.
  • R: a fourth move from their Deadlock kit, items or melee.
  • Q (equipment): their Deadlock ultimate. Every hero starts the run holding their own (120 s cooldown, about as strong as the Preon Accumulator). Swap it away and it stays on the ground; anyone, Commando included, can find the ults in chests. The pickup is a little figure of the hero.
• Haze: Twin SMGs, Sleep Dagger, Smoke Bomb, Phantom Strike (blink behind a target, three slashes that cut everything around it); Q Bullet Dance. Passive: Fixation stacks on every hit and bursts.
• Abrams: Shotgun, Siphon Life, Shoulder Charge, Haymaker (locks on and rushes into a heavy punch); Q Seismic Impact (hover, aim, crash down).
• Seven: Shock Rifle, a yellow Lightning Ball that slows over enemies, Static Charge, and Storm Cloud (fly for 10 s inside a storm that shocks the 3 nearest enemies); Q Thunderhead.
• Infernus: Flame Gun, Napalm, Flame Dash (a run that leaves fire behind), Torment Pulse; Q Concussive Combustion. Hits build Afterburn.
• Mo & Krill: Krill's shotgun, Sand Blast, Burrow (travel underground, burst out spinning), Tag Team; Q Dust Devil, a sand tornado.
• Viscous: goo blobs, Splatter, The Cube, Puddle Punch; his puddles top up his ammo; Q Goo Ball.
• Rat King: Sovereign's Decree spreadshot, a hopping Scrap Grenade, Royal Pestments, Rule, Ratannia! (a banner leap), a cape, a tail and a crowd of Deadlock's rats; Q Rat Swarm.
• Billy: Biquette the machine gun, a 3-hit Bat combo that juggles enemies in the air, Bashdown, Rising Ram (chains haul everyone into the air); his air jump is a goring dodge and he never takes fall damage; Q Chain Gang, up to 20 chains.
• Deadlock voice lines play at the right moments, read from your Deadlock install like the other sounds.
• Each hero is balanced against a Risk of Rain 2 survivor (the hero pages show the numbers) and levels up like one.
• If Deadlock ever changes one hero so it can't be read, only that hero shows a red "!" tile (hover it for why); the others still work.
• Co-op with up to 4 players: Risk of Rain 2's own lobby and Steam invites. Every player needs this mod (the same version) and their own Deadlock install. Melty players on the same version can join too.

About DeadlockExtract.exe

The mod comes with one small program, DeadlockExtract.exe. It reads the heroes from your own Deadlock install (opened read-only) and saves them to %LOCALAPPDATA%\DeadlockOfRain\cache for the mod. It makes no network connections and changes nothing else. It is a separate program because the Valve file reader it uses only runs on .NET 10, which Risk of Rain 2 can't load. GitHub builds it in public from the source in extractor/: the release page links the build log and lists its SHA-256, the same file that is in this download. Some antivirus programs distrust any new unsigned program; if yours removes it, restore it from quarantine.

Changelog

1.0.0

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6819 (v1.0.0, 2026-10-25).
• Thunderstore gets all eight heroes: Haze, Abrams, Seven and Infernus, now joined by Mo & Krill (MUL-T's match), Viscous (REX's), Rat King (Captain's) and Billy (Mercenary's). Every hero's abilities are described on its hero page.
• Billy, the newest: Biquette the machine gun, a 3-hit Bat combo that dodges onto enemies in the air and juggles them, Bashdown, Rising Ram (chains haul everyone around into the air) and the Chain Gang ult (up to 20 chains of 1500 %, one per enemy in sight, leftovers to bosses). The G.O.A.T. passive turns his air jump into a goring dodge, and he never takes fall damage.
• Pick your heroes: on the first start a window lists every hero with the time it takes to read; tick the ones you want and press Go. Installed heroes are marked, skipped ones come back next start, and the window stays away once every hero is installed. Playing online needs the same heroes on every PC: install all of them to join any game.
• The first start is about 15 times faster: all eight heroes in about 2 minutes (it took 16 to 34 minutes). Abrams alone went from 9 minutes to 14 seconds (Deadlock reader 1.8.0).
• The title screen's two buttons show their names again, "Join the Risk of Deadlock Discord" and "Deadlock Hero Info" (with all eight heroes beside it); they were blank.
• First start fixed for more PCs: the "Deadlock folder" setting accepts a path ending in \ and the game or game\citadel folder too (a trailing \ used to break the reader); when an antivirus has removed DeadlockExtract.exe the game says so instead of asking you to install Deadlock; and if the reader ever stops responding for 10 minutes the loading screen stops waiting and tells you what to do.
• The Deadlock reader is version 1.8.0, built in public by GitHub: effect models, capes and Deadlock's colours read from your install like the heroes.
• A big "Join the Discord" button at the bottom right of the title screen opens the mod's Discord community (FAQ, hero requests, news), and a "Hero Sheets & Damage" button above it opens every hero's ability and damage pages.

0.11.0

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6819 (v0.11.0, 2026-10-23).
• The loading screen now says clearly what is happening: a big "Deadlock of Rain" banner names each hero while it is built from your own Deadlock install ("Building your Deadlock heroes: Abrams (2 of 7)"), with a timer and "The game is not stuck", and a list shows each hero as it gets ready.
• Melty's setup screen says it too (Deadlock reader 1.7.0): it explains that it is reading the heroes' models, animations, icons and sounds from your Deadlock install, that this happens once and again after each Deadlock update, and names each hero as it goes.
• Because the reader is new, the heroes are read from Deadlock once more on the first start of this version (a few minutes).
• Checked against Deadlock's update of 23 October (build 6819): every hero reads and plays.

0.10.0

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6817 (v0.10.0, 2026-10-22).
• Rat King joins as the seventh playable hero: Sovereign's Decree, the hopping Scrap Grenade, Royal Pestments, the banner leap Rule, Ratannia! and the Rat Swarm ult.
• Billy takes Rat King's place as the locked "coming soon" tile.
• Co-op: a friend's Scrap Grenade now always hits on the host too (it could fly over the enemy it hit on their screen).
• Checked against Deadlock's update of 22 October (build 6817): every hero reads and plays.

0.9.1

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6813 (v0.9.1, 2026-10-22).
• Seven is redesigned: a yellow Lightning Ball that slows to half speed over enemies, a retuned Static Charge, and Storm Cloud on R in place of Power Surge (fly for 10 s inside a storm that shocks the 3 nearest enemies). Thunderhead has its own icon.
• Abrams' Shoulder Charge no longer throws an error when it hits an enemy the moment it spawns.
• Co-op: a friend's Concussive Combustion (Infernus' Q) always explodes on the host; on a laggy connection it could fizzle.
• Playing together through Melty: your game is open to friends from the title screen, so Melty's Join always has an address; a Singleplayer run stays solo. A friend who joins before you start waits in your lobby instead of being told it failed, and Melty never hands out a lobby you've left.
• Rat King's "coming soon" tile is a black silhouette.

0.9.0

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6807 (v0.9.0, 2026-10-21).
• A seventh hero, Rat King.
• Heroes and effects can use Deadlock models with their own animations, and swinging capes (extractor 1.6.0).
• Clips that left a hero's root turned no longer carry that turn into the next clip.
• Effect models keep Deadlock's vertex colours and material tints (extractor 1.6.1).
• Every hero shows its magazine (rounds/magazine) just above the M1 icon of the skill bar.

0.8.0

• A sixth hero, Viscous.
• Moves of a future hero can use Deadlock's own effect models, read from your install like the heroes (extractor 1.5.0).

0.7.4

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6795 (v0.7.4, 2026-10-20).
• The game no longer crashes when you quit after playing a run. It was Risk of Rain 2 and BepInEx together (it happened without this mod too); the mod now stops it.

0.7.3

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6795 (v0.7.3, 2026-10-19).
• Closing the game shuts the mod's Deadlock sound down properly first.

0.7.2

• Built with Risk of Rain 2 build 25921972 and Deadlock build 6795 (v0.7.2, 2026-10-19).
• A hero that can't be read from your Deadlock no longer disappears: its spot in character select shows a red "!" (it can't be picked), and hovering it says why. Every other hero still works.
• Heroes whose model Deadlock moved to another folder are found anyway (the mod now asks Deadlock's own hero list where each model is).
• Every problem message names the Risk of Rain 2 and Deadlock versions the mod was built with, and the ones on your PC.
• The setup shows each hero as it is read (ready or skipped) and a summary at the end.

0.7.1

• Works with Deadlock's update of 19 October 2026 (the heroes couldn't be read after it).
• If Deadlock ever changes one hero so it can't be read, only that hero is missing (a message on the title screen says which); the others still work.

0.7.0

• First release: Haze, Abrams, Seven and Infernus from Deadlock as Risk of Rain 2 survivors, each with their Deadlock ultimate as a Q equipment.
• The mod finds your Deadlock install and reads the heroes on the first start (the loading screen waits a few minutes, once per Deadlock update).
• Co-op with up to 4 players.
