How to play BONELAB with a friend: BONELAB Fusion

The definitive VR multiplayer mod: physics-synced avatars, lobbies over Steam, and a module system other mods build on. Updated all through 2026. Steam lists BONELAB as single-player, so it won't show up in Steam's own "games we both own" view as something you can play together — Ready Up counts it anyway, marked "Via mod", and you can hide mod-only games with one filter if that's not your thing.
