Where Are Cult of the Lamb Save Files Located?
Where Cult of the Lamb keeps slot saves and its ten deep automatic backup folder on each OS.
Last updated
Cult of the Lamb keeps saves in a Massive Monster folder under AppData\LocalLow, with slot_X.json files in saves and timestamped pairs in backup. The game retains the ten most recent states per slot automatically, which is a deeper safety net than most Unity titles bother with.
Slot files are plain JSON, and that tempts editing. Back up before touching anything: a malformed edit loads as a missing cult rather than an error message. The Steam Deck path follows the standard Proton compatdata layout for app ID 1313140.

Frequently asked questions
How do I roll back a Cult of the Lamb save?
Open the backup folder, pick the meta_X.NNN and slot_X.NNN pair from before the incident, copy them into saves, delete the live meta_X and slot_X, and rename the copies to drop the .NNN suffix. The pair must travel together or the slot refuses to load.
How do I move my cult to a new PC?
Copy the saves folder contents (slot_X.json files) to the same path on the new machine after running the game once. Steam Cloud usually handles it, but the manual copy covers disabled sync and cross store moves.
