Original mod: Dantor's Mental Hospital

What this port changes

  • Adds compatibility with v81.
  • Updates the old DunGen assembly references used by the mod.
  • Removes access to the obsolete ExtendedDungeonFlow.dungeonDefaultRarity field used by older LethalLevelLoader versions.

Compatibility note - CullFactory

On v81, CullFactory can incorrectly cull the player's flashlight beam in some sections of the hospital.

If this happens, blacklist the Mental Hospital dungeon in CullFactory using:

HospitalFlow

The dungeon itself can otherwise remain enabled normally.

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:
