🪐 Lethal Dissonance V81

An immersive, vanilla-enhancing modpack featuring 127 carefully balanced mods. Designed for complete immersion into an atmosphere of paranoia, deep environmental and storytelling. Balanced for 4-8 players.

If this is your first time playing, please do not use Discord or other external voice messengers. Use the in-game proximity voice chat—this game has plenty of mechanics built around sound and speech.

WARNING: The first launch might take a while, or the console may seem stuck while loading mods—this is completely normal, just restart the game. There is also a known bug with the in-game friend invite button; I highly recommend inviting players directly through Steam. The exit button may also occasionally crash the game, but these crashes are absolutely harmless. It is best to close the BepInEx console window directly, and the game will close instantly.

🎧 Total Audio Overhaul

Thanks to the Lethal_Resonance mod, most sounds in the game have been completely remade. The gameplay is now enveloped in a dark, bleak, and terrifying ambient soundtrack, while the reworked music heavily intensifies the feeling of anxiety.

👹 New Monsters

HUGE SPOILERS! DO NOT READ THIS SECTION IF YOU WANT TO KEEP THE GAME UNPREDICTABLE

The Biodiversity mod introduces several new creatures designed primarily to expand the local fauna:

1. Bloombird 🦢: A true saboteur that doesn't deal direct physical damage. Instead, its target is your ship. Landing on the roof, it begins messing with the crew: switching players on the monitor, shutting down lights, and locking doors.
2. Aloe 🌱: Bracken's "good twin." It wanders around the facility looking for wounded players and sneaks up from behind to drag them to a safe spot and heal them. However, it will not protect you from other monsters.
3. Coilcrab 🦀: This friend only moves when you aren't looking at it. It has a nasty habit of exploding, but after it dies, you can harvest valuable skin from it.
4. Ogopogo 🐛: A marine leviathan that will drag you underwater and consume you.
5. Rolling Giant 💀: Adds a monster with a unique mechanic. It pursues the player only as long as they maintain direct eye contact with it.
6. Masks (Mirage) 🎭: Perfectly mimic your and your friends' appearances and even speak in your own voices to throw the crew into absolute confusion. This is all possible thanks to a finely tuned Mirage mod. All masks look highly convincing, can carry items, and speak coherent sentences.
7. Mimics 🚪: Adds fake fire exit doors that attack the player when they try to use them to escape.
8. Blood Witch: Adds a new monster—an old hag who loves to spawn inside the Asylum.

🧱 New Facilities (Interiors)

• Generic Interiors: A versatile mod that adds a massive variety of complexes, such as drains, towers, liminal facilities, and more.
• A collection of specialized interiors: Acf interior, Liminal House, and Gothic Monastery. Each of the 15 custom layouts is individually matched to the specific theme of the moons.

🌎 New Planets (Moons)

• Egypt: A desert moon with two fire exits and realistic ancient architecture.
• Crypt: A bleak moon surrounded by panel high-rises in the style of Murino city. Residential areas and an atmosphere of utter hopelessness are everywhere.
• Atlas Abyss: The homeland of mimics. They feel right at home here, so your chances of being deceived skyrocket.
• Acidir: A moon featuring a massive ancient mansion surrounded by a unique toxic-green nature.
• PsychSanctum: A moon with a heavy, oppressive atmosphere and an equally unsettling ambient soundtrack.
• Esoterica: A completely dead moon created SOLELY FOR THE COMPANY CRUISER. Features a massive highway, a bridge, and three entrances. There is absolutely nothing to do here without a car. This is a late end-game moon.

🛠 Convenience, Localization, and Quality of Life

• SellMyScrap: A mod that eliminates the routine of selling junk at the Company building, allowing you to sell scrap from the comfort of your ship without wasting time.
• ReservedItemCore (along with ReservedWalkieSlot and ReservedFlashlightSlot) 🔦: Provides two additional dedicated slots for the walkie-talkie and flashlight, allowing you to use your main inventory slots exclusively for scrap. It allows hands-free walkie talkie usage by pressing [X] without holding it. Instantly toggle your flashlight by pressing [F], regardless of what item you are currently holding.
• GeneralImprovements 🛠: A global mod that configures half of the game's elements. Tuned for better balance and general convenience. Adds monitors to the ship with extra useful info.
• Lethal Regeneration ❤: A health regeneration mod. Health restores faster inside the ship than outside. This ensures that a minor, non-lethal mistake at the start doesn't ruin the rest of your run.
• Better Stamina 🏃: Solves the issue of excessively slow stamina recovery. Strictly balanced so it doesn't make the game too easy.
• AlwaysHearActiveWalkiesFork: Makes walkie-talkies more realistic with regards to audio positioning. Now, your friend's walkie-talkie will be clearly audible in 3D space if you stand nearby.
• OxygenDisplay 🫧: Clearly shows the amount of oxygen underwater, helping you realize exactly when it's time to surface.
• BeltBagConfig 👛: Helps manage ship space more efficiently and speeds up quota fulfillment by allowing the bag to collect scrap. I strongly advise against running around inside the facility with this bag, as it completely breaks the core balance of the game.
• Death Informers: The Coroner, Killedbyfake, and CoronerMimics mods output detailed causes of death for crew members, revealing exactly which mimic or mask tricked and ate your friend.
• CullFactory: Unloads the interior layout of the facility when you are outside, significantly boosting game stability and performance.
• MoreCompany: Expands the lobby limit, allowing you to gather large groups of friends.
• Hitmarker: Adds a visual hit marker and a distinct audio response when dealing damage to enemies.
• Vehicle Improvements: The CruiserAdditions and BetterVehicleControls mods aim to fix the Company cruiser. The first fixes physics bugs, while the second simplifies driving controls, making the vehicle much more responsive.
• RemoveInteriorFog: Permanently removes the cursed interior fog inside facilities generated by vanilla weather.
• JetpackFixes: Fixes the jetpack, eliminating random mid-air explosions.

🤯 New Mechanics and Dynamic Events

HUGE SPOILERS! DO NOT READ THIS SECTION IF YOU WANT TO KEEP THE GAME UNPREDICTABLE

• InsanityMod 🤯: Completely reworks the insanity mechanic. Being alone and wandering in the dark for too long is now lethal—losing your mind causes the player to die and join the ranks of the mimics. This heavily threatens solo players or occurs during "Paranoia" weather.
• Interactive Loot: The Immersive scrap, MoreScraps, and SlaughterHouseScrap mods add a massive amount of interactive scrap to the maps, including functional flashlights, weapons, and scanners.
• WiseWeapons: Allows you to use certain pieces of scrap as melee weapons, significantly expanding your arsenal.
• Lethal Things: Adds new items to the map generation and the Company store. You can now officially buy a frag grenade for $150.
• FacilityMeltdown: A chaotic event that triggers with a 60% chance when a player removes the apparatus (reactor). You will have exactly two minutes to evacuate before the facility blows sky-high, while monsters aggressively try to block your escape. Combined with the new creatures, this generates tons of insane gameplay moments.
• Arachnophilia: A mod that completely reworks spiders, making them more durable but lowering their single-hit damage. It also adds a creepy spider den interior and increases the amount of cobweb traps.
• EnhancedSpectator: Reworks the post-death spectator camera, conveniently binding controls to the functional keys (F1–F6).
• CoilHeadStare: Makes the Coil-Head a significantly creepier opponent during prolonged eye contact with the player.
• Weather Conditions: The combination of WeatherRegistry and LethalElementsForky refines the weather system, adds new weather effects, and increases the credit rewards for extreme risks—ideal for meeting high quotas in the late game.
• CameraOverhaul 📹: Completely reworks the first-person camera. Adds realistic tilting, rotational inertia, and dynamic bobbing while running or jumping. This drastically heightens immersion and the physical feel of your character in the environment.
• SnatchinBracken: The Bracken now prefers to play games with you.
• DimmingFlashlights: Flashlights are now dynamic, and their performance quality depends on their current battery level.

😎 Cosmetics and Fun

The modpack includes numerous mods for custom suits and altered sound effects. The BetterEmotes mod has been added (introducing 8 unique custom emotes). Landmine explosion sounds and shovel hit SFX against enemies have been replaced with funnier alternatives. All suits from the MoreSuits mod and other packs are unlocked by default.

The main focus of this modpack is to expand the vanilla experience and eliminate routine by offering maximum variety in mechanics and gameplay. I created this modpack simply because I wanted to deliver a high-quality product. I had to finish the game for the developer and manually reconfigure mods that had terrible balance "out of the box." A massive 170 hours of playtime and deep knowledge of modding truly shine through in this stable build.

Thank you for downloading, I hope you enjoy it! Leave a like if you want me to keep pushing updates.

Have a great game, contractors!
