About this mod Author’s original text

Rayllan

A short, hunched, big-headed monster with glowing red eyes that stalks the facility.

  • Wanders the halls with quiet raspy chittering.
  • Screeches when he spots you, then chases - starting slow and getting faster the longer the chase lasts (up to faster than a sprinting employee).
  • Gives up a few seconds after you break line of sight.
  • Hits for 35 damage. Takes about 4 shovel hits to kill.
  • Terminal bestiary entry: rayllan

Config

BepInEx/config/marlko.rayllanmonster.cfg -> SpawnWeight (default 40). The host's value is used.

Every player in the lobby needs this mod.

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.

Install these first, or the mod will not work:
