Lethal Company Modding on OpenMods

A 2023 indie shocker with an explosively-active mod scene

Lethal Company (2023) is Zeekerss's co-op horror game that became a Steam phenomenon overnight. The modding scene followed within weeks, built on BepInEx, distributed via Thunderstore, managed through r2modman. The catalogue grew explosively because Lethal Company's design (peer-to-peer co-op, easy-to-modify Unity codebase, viral popularity) is perfect for community modding.

The mod ecosystem is similar in shape to Valheim or Risk of Rain 2, BepInEx + r2modman + Thunderstore, and the patterns transfer directly.

The toolchain

• r2modman: community mod manager, Thunderstore-based.
• BepInEx: Mono Unity loader.
• LCSoundTool, Unity Netcode Patcher: common framework dependencies.
• Thunderstore Lethal Company section: the canonical hub.

What you'll find on OpenMods

LC mods live overwhelmingly on Thunderstore. GitHub hosts source for the larger projects. OpenMods catalogues GitHub-published LC mods.

Practical notes

• Multiplayer mod parity is mandatory. Every player must have the same mods. r2modman handles this via profile codes.
• Patches break mods frequently. Zeekerss updates Lethal Company regularly; mods catch up within days for popular ones.
• Catalogue grows fast. New mods land daily. Set a baseline mod list and update it periodically rather than chasing every release.
• Cosmetic vs gameplay mods. Cosmetic mods (skins, voice replacements, custom monsters) are abundant. Gameplay-changing mods (new moons, new enemies, new mechanics) are heavier and require more coordination.
