The Complex

I found something.

All these rooms. This place builds them.

A procedurally generated Backrooms themed interior for Lethal Company heavily inspired by Kane Parsons' Backrooms.

With 5 unique biomes and over 200 unique room tiles, this is one of the largest interior mods for Lethal Company. (Load times with this mod will be longer due to the immense size of the interiors being generated, lower end PCs will suffer performance issues!)

Features

• Every map is new. Rooms are generated fresh each landing, and the complex drifts from one biome into the next.
• The Chasm: a pit twelve storeys deep, lit fainter the further down you look. Plus rare rooms to find.
• Working TVs playing video, and speakers playing music that echoes through the rooms.
• Lights that flicker, buzz and fail, ceiling fans that spin, and vents you can hear enemies crawling through.
• Multi-storey rooms with balconies, stairs and open drops.
• Deep pits that sometimes drop you somewhere else in the complex instead of killing you.
• Real water in the Poolrooms.
• Room acoustics: sound is muffled through walls and echoes in large rooms.
• Configurable spawn weights, or force it onto every moon.

Biomes

Settings

• The Complex rolls alongside the other interiors. Its weights are under Spawning in BepInEx/config/backrooms.level0.interior.cfg (LevelTags, PlanetNames).
• Set ForceAllMoons to true (host only) to get The Complex on every moon.
• Everyone in the lobby needs the mod, on the same version.
