LethalCompanyV81Pack

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.
