InsanityMod (v81 rebuild)
⚠️ Unofficial rebuild for Lethal Company v81, maintained by Cpt.Dristyler.
Not affiliated with or endorsed by the original author. Install this instead of the
original, not alongside it.
A sanity system for Lethal Company. Insanity rises inside the facility and drains
outdoors / in light / near teammates. High insanity brings tunnel vision, camera shake
and voice distortion; at 100% an optional transformation into a Masked. Includes a HUD
ring, an end-of-round "Peak insanity" stat, and a custom Paranoia weather.
This rebuild (1.0.7) — by Cpt.Dristyler
- Fixed online HUD/round start for clients. Round start previously ran only from the
server-only StartOfRound.StartGame, so on non-hosts the insanity ring stayed
invisible. An idempotent round start was added to
RoundManager.FinishGeneratingNewLevelClientRpc (runs on everyone).
- GhostGirlBoostPatcher runs host-only (IsServer) — removes Ghost Girl desync online.
- InsanityNetworkHandler.RegisterHandlers is idempotent — no duplicate NGO
named-message registration each round.
- Rebuilt under the.NET 8 SDK against current dependencies (WeatherRegistry 0.8.8 /
MrovLib 0.4.3). GUID com.insanitymod.lethalcompany unchanged — configs stay
compatible.
Online note
Masked transformation and final stats use server-side NGO named messages. The mod must
be installed by the host and all players on the same version (architectural requirement,
not a bug).

Dependencies
- BepInEx 5.4.2100
- mrov-MrovLib 0.4.3
- mrov-WeatherRegistry 0.8.8
Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- 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.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- 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:
