Dungeon Generation Plus

An API to expand the compatibilities of Lethal Company's dungeon generation.

This mod is for interior modders to add to their projects if they so desire. By itself, this mod cannot improve the dungeon generation of vanilla dungeons.

This API was originally a part of the custom interior, Scarlet Devil Mansion.

How to Setup and Use

Please refer to the wiki for documentation on utilizing this API for your custom interior.

Dev Debug Tools

Activate this feature in this mod's config, then press M while inside the ship alone.

Allows you quickly generate dungeons inside Lethal Company. You can edit most (but not all) values of the DungeonFlow and DunGenExtender assets to quickly see how the changes would affect the dungeon generation.

See this (thread)[ for the feature in action.

Multiple Main Paths

The prominent feature of this API is the ability to seemlesly add multiple main paths to your interior. Below are some examples.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
