About this mod Author’s original text
Lethal Company v81 Friends Pack
A vanilla-plus modpack for Lethal Company v81, built for a group of friends who want the
game to feel like Lethal Company, only smoother, bigger and with more to discover.
What you get
- Bigger lobbies (up to 16 players) and proximity-friendly quality of life.
- Bug fixes and performance mods so v81 runs cleanly for everyone.
- A curated slice of new moons, interiors, monsters and scrap that fit the vanilla tone.
- Emotes, suits and cosmetics for fun, plus richer weather and ambience.
- No difficulty overhauls. Everything is configurable and the defaults are tuned for a casual-to-medium crew.
Every mod in this pack was checked against on 5 September 2026 for a v81-compatible
release. If an update to the game lands, check the CHANGELOG or re-run the build script (see below).
Installing
- Install a mod manager: Mod Manager
or r2modman (lighter, no Overwolf).
- Select Lethal Company, create a profile, open Online, search for this pack and hit Download.
All dependencies install automatically.
- Press Start modded. The host and every friend must be on the same pack version.
Everyone should install the same version of the pack. Client-only mods (cosmetics, HUD, sound) are safe to
toggle per person, but keep the server-side mods identical to the host or you will desync.

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:
