Practice Sandbox

A practice and testing sandbox for Lethal Company.

Practice Sandbox creates a dedicated practice arena and lets you spawn enemies and items, toggle invincibility, reset encounters, and control the sandbox from either normal in-game chat or the ship Terminal.

Thunderstore package version: 0.1.79
Current plugin build used to prepare this package: 0.1.79.8

Features

• Dedicated practice arena with its own NavMesh and enemy activity area.
• Spawn enemies on demand, including indoor, outdoor, special, and internal entities supported by the current game build.
• Spawn store items, scrap, weapons, and special/system items.
• Use the same Practice commands from normal in-game chat or the ship Terminal.
• Toggle invincibility and manually set, heal, or damage player HP.
• Reset spawned enemies back to the practice enemy area.
• Delete spawned enemies/corpses or dropped practice items independently.
• Enemy hitbox visualization and player status display tools.
• Special handling for several enemies whose vanilla behaviour needs extra setup in a sandbox environment.
• Multi-Kidnapper-Fox practice support with persistent Vain Shroud patches and recovery after tongue/kill interactions.

Starting Practice Mode

1. Start a game as normal and use the ship Terminal.
2. Enter practice (or routepractice).
3. Pull the ship lever and land.
4. After the Practice arena is created, commands can be entered either:
   • in normal in-game chat, or
   • directly in the ship Terminal.

A p, ps, or practice prefix is not required after Practice mode is active.

Main Commands

Enemies

Items

Player / Practice controls

The in-game datae, datai, and datas commands are the authoritative lists for the current build and include more aliases than this README.

Installation

Thunderstore / r2modman

Install the package with your compatible mod manager. BepInExPack is declared as a dependency and should be installed automatically.

Manual

1. Install BepInEx for Lethal Company.
2. Copy PracticeSandbox.dll to a folder under BepInEx/plugins/.
3. Start the game.

Notes

• This mod is intended for practice/testing sessions rather than normal progression.
• It is primarily developed and tested in a host/local practice environment. Multiplayer behaviour outside that use case is not guaranteed.
• Practice mode intentionally changes world presentation, enemy spawning, and several player/enemy behaviours while active.
• During Practice mode, recognized Practice commands take priority over conflicting vanilla Terminal commands.
