Save file locations

Windows (Steam)
%USERPROFILE%\AppData\LocalLow\Massive Monster\Cult Of The Lamb\saves

Full path: C:\Users\<YourName>\AppData\LocalLow\Massive Monster\Cult Of The Lamb\saves\ . Your saves are slot_0.json (Slot 1), slot_1.json (Slot 2), etc.; each meta_N.json holds that slot's summary.

Xbox Series X|S / Xbox One
My games & apps > <Game> > Manage game > Saved data

Xbox saves sync automatically to the cloud with your Microsoft account; there is no user-accessible save file on disk.

PlayStation 5 / PS4
Settings > Saved Data and Game/App Settings > Saved Data

Console saves are sealed and can't be copied as raw files. Back them up to PS Plus cloud or a USB drive from this menu.

Cloud saves

On PC, Cult of the Lamb uses Steam Cloud, so your slot files sync across machines with the same account. Close the game before restoring a backup so Steam Cloud doesn't overwrite it with the newer online copy.

  1. Press Win + R to open the Run box.
  2. Type %userprofile%\AppData\LocalLow and press Enter.
  3. Open Massive Monster > Cult Of The Lamb > saves to find slot_0.json, slot_1.json and their meta_N.json files.
  4. Copy the whole save folder somewhere safe before editing, modding, or moving PCs.

Save problems & fixes

Cult of the Lamb save won’t load or says it’s corrupt

Many games keep an automatic backup next to the save (a .bak or numbered copy) — close the game, copy that backup over the broken file, and reopen. On Steam, also right-click the game → Properties → Installed Files → Verify integrity of game files.

My Cult of the Lamb save is missing or the folder looks empty

You are usually looking one level too high — open the numbered profile / Steam-ID sub-folder inside the path above, not the parent. If it is still empty, cloud sync may not have finished writing before the game overwrote the local copy; reconnect and let the cloud sync finish before launching.

Cult of the Lamb progress rolled back after a cloud save conflict

When Steam or the console reports a save conflict, always keep the version with the LATER timestamp. Choosing the older cloud copy overwrites newer local progress — the most common cause of “lost hours.” If unsure, disable cloud sync, back up the local folder first, then re-enable it.
