Lethal Company Mod Menu Injection Guide

Admin Aug 1, 2026 2 min read 127 views

Lethal Company Mod Menu

by TheHolyOneZ — a client-side internal mod menu for Lethal Company
(Unity, Mono build). Single DLL, no dependencies, Harmony is embedded.


Requirements

  • Lethal Company (the normal retail / Steam Mono build)
  • ZyMono — github.com/TheHolyOneZ/ZyMono
  • Windows (run the injector as Administrator if it can't see the game)

How to inject

  1. Start Lethal Company and load into a lobby.
  • Hosting is recommended (some features are host-only — see below).
  1. Run zymono.exe and select the Lethal Company process in the Targets list on the left (it refreshes automatically).
  2. On the right pane, click under Mod, choose .dll, and select:
   LethalCompanyMod.dll
  1. Scroll down a little and fill in the fields exactly (case sensitive):
   Namespace :  LethalCompanyMod
   Class     :  Main
   Method    :  Init
  1. Leave the route on Auto and click Inject.
  2. Press Right Shift or Insert to open the menu.

One injection is enough. If ZyMono reports success but nothing shows,
just press Right Shift / Insert — the menu loads on the first frame.


Controls

| Key | Action |
|------------------------|---------------------------|
| Right Shift / Insert | Open / close the menu |
| F | Toggle NoClip / Fly |

While flying: WASD move, Space up, Ctrl down, Shift to boost.


Feature overview

| Tab | What it does |
|-----|---------------|
| Self | God mode, unlimited stamina/battery, speed & jump multipliers, NoClip/Fly, extended grab reach |
| Visuals | Player/enemy/loot/hazard/exit ESP with boxes, tracers and distance; fullbright & night vision |
| World | Freeze time, no deadline, add/set credits & quota, teleports, unlock doors, free moon routing |
| Host | Force start/end round, kill/stun enemies, item & monster spawners, detonate mines, untargetable |
| Players | Live roster with per-player teleport / lure / kick / revive |


Host vs client

Lethal Company is host-authoritative. Money, quota, day/deadline, enemy
AI, spawning and kicking only take real effect when you host the lobby.
As a client those items no-op or revert — the menu tells you when.

Things that DO work as a client: the whole Self tab (god mode, stamina,
speed, jump, noclip, battery, reach), all ESP + fullbright, teleports,
Unlock All Doors, Detonate Mines, and Free Moon routing.


Eject

Use the Unload button in the menu title bar to remove the mod cleanly,
or eject the assembly from ZyMono (Main.Unload).
