What it does
Insanity meter
Insanity (0–100%) accumulates while you're inside the facility and drains while you're outdoors during the day. The ship is a partial refuge — it drains insanity while the lights are on, and creeps it up slowly when they're off.
- Solo in the facility: ~10 minutes to 100%
- On the ship: slowly drains with lights on (−0.3/s), creeps up slowly when dark (+0.15/s)
- Outdoors (daytime): slowly decays back toward 0
- Outdoors (night / Eclipse): insanity rises instead of falling
- On the Company moon (Gordion): drains regardless of lights — the Company is a thematic refuge
- Resets each round — every new expedition starts fresh
Things that make it worse
| Trigger | Effect |
|---|---|
| Visible enemy nearby | +rate per second (scales by enemy type) |
| Watching a teammate die | instant spike |
| Paranoia weather | rate multiplier |
| Night outdoors | slow rise instead of decay |
| Eclipse weather outdoors | faster rise than night |
| Underwater | +0.4/s |
| Ship with lights off | +0.15/s (mild creep) |
Enemy threat scale (examples): Bracken / Ghost Girl = 2.0×, Jester / Coilhead = 1.5×, Forest Giant / Masked = 1.4×, Sand Worm = 1.8×, Thumper = 0.8×
Things that make it better
| Condition | Effect |
|---|---|
| Teammate within 6m | −0.15/s |
| Flashlight on / in ship | −0.1/s |
| Near a facility light | −0.1/s |
| Ship with lights on | −0.3/s (base rate) |
| TZP-Inhalant effect active | −1.0/s |
| On the Company moon (Gordion) | −0.5/s |
Being with a teammate near a light source in the facility effectively keeps insanity stable — unless the apparatus has been removed. TZP-Inhalant is a strong safety valve: one inhale (~17 s effect window) recovers ~17%. Note: TZP does not reduce insanity inside the facility after the apparatus has been removed (the apparatus-removed penalty disables all in-facility recovery).
Effects at high insanity
Things start happening as insanity climbs. Find out for yourself.
Spoilers — click to reveal
70% — Voice distortion
Nearby teammates' voices begin to sound subtly warped. The mod also captures a rolling 30-second buffer of teammate voice chat and starts playing back distorted snippets spatially in 3D — you'll hear phantom voices from positions that seem to move.
80% — Tunnel vision
A deep red vignette slowly pulses in from the edges of the screen. The pulse and color intensity increase toward 100%.
Also at 80%+: the Ghost Girl (DressGirl) slightly increases her haunt speed while targeting you.
90% — Camera shake
Perlin-noise position and rotation jitter on the camera. Starts subtle, gets pronounced at 100%.
100% — Transformation
Insanity peaks. Movement gradually slows to a halt, the screen fades to black, and a Masked enemy spawns at your position wearing your suit. You die.
The transformation can be disabled in config (EnableMaskedTransform = false).
Apparatus removal
Pulling the apparatus triggers an immediate insanity spike for everyone in the round. For the rest of the round, insanity-reduction buffs (teammate proximity, flashlight, facility lights) no longer work inside the facility — insanity can only rise in there. Outdoors is unaffected.
Paranoia weather
A custom weather event. During Paranoia, insanity accumulates faster in the facility and enemies are more active. Appears at roughly 3% chance per night (configurable).
HUD
A small ring meter in the bottom-right corner of the screen shows your current insanity percentage. Color shifts white → yellow → red as it fills.
End-of-round results
After the ship leaves, the host broadcasts each player's peak insanity for the round to all clients.
Configuration
All values are in BepInEx/config/com.insanitymod.lethalcompany.cfg.
