Adds Scp966 as a monster in Lethal company

About this mod Author’s original text

SCP966-SleepKiller

This mod adds SCP 966 as a monster in Lethal Company. To see it, the player will have to buy the night vision goggles from LateGameUpgrade. The mod will work without LateGameUpgrade.

[NEW] YOU CAN NOW SEE THE MONSTER BRIEFLY WHENEVER YOU SCAN

Here are its phases and how it works in game if you wanna spoil yourself (spoilers aside tho, the night vision goggles from Lategamecompany might help with SCP 966)

LateGameUpgrade

Roaming Phase

It will go around until it detects a player. If the player's stamina is above 10, it will go into the Tiering Phase. If the player's stamina is under 10, it will go into the Chasing Phase.

Tiering Phase

It will follow the player around, adding to their weight 52 lbs. if the players stamina reaches under 20%, SCP966 will go to the chasing phase

Chasing Phase

When in the Chasing Phase, it will hunt down the player until they are dead or leave the building. Then, it will go back into the Roaming Phase.

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:
