Installation and rollback covers the standard BepInEx folder layout. Check the individual mod author’s instructions for libraries and release requirements. A generic loader version does not establish that every plugin works with the current game patch.

Gunsaw Genetics and a separate multiplayer sprite replacer can overlap in skin-changing functionality. Their detail pages distinguish the original mod from its multiplayer forks and patches. The historical Layer Unlocker record concerns the demo and is not a confirmed full-release expansion.
