Where Are Mortal Sin Save Files Located?
Mortal Sin keeps run progress in LocalLow under Doronik Games, a handful of .sav files that Steam Cloud syncs between machines.
Last updated
Mortal Sin saves to %USERPROFILE%\AppData\LocalLow\Doronik Games\Mortal Sin, the LocalLow tree Unity games use. Each .sav file is a slice of state: run progress, unlocked classes, story beats, and the meta upgrades that survive death.
The folder stays tiny, a few megabytes even after dozens of hours. That makes copying it worthwhile: carry progress between machines, back it up before a big patch, or roll a run back after a death that felt unfair. Steam Cloud covers the same files, which is why a fresh install usually greets you with your unlocked classes intact.
Where Mortal Sin stores this, by platform
%USERPROFILE%\AppData\LocalLow\Doronik Games\Mortal Sin
The .sav files hold run and meta progression, including unlocked classes and story progress. Steam Cloud syncs them automatically. AppData is hidden in Explorer by default, so paste the path into the Run dialog instead of clicking through folders.
~/.local/share/Steam/steamapps/compatdata/1494810/pfx/drive_c/users/steamuser/AppData/LocalLow/Doronik Games/Mortal Sin
Steam Deck and Linux run the Windows build through Proton, so saves land inside the prefix for app ID 1494810.
Frequently asked questions
How do I reset all progress in Mortal Sin?
Close the game, then move or delete the .sav files in the LocalLow folder. Steam Cloud restores them on the next launch, so either disable cloud sync for the game first or remove the files again right after launching.
Can I transfer my Mortal Sin unlocks to another PC?
Copy the whole Mortal Sin folder into the same LocalLow path on the other machine while the game is closed. Unlocked classes, story progress, and upgrades carry over exactly, since nothing in the save is tied to your Windows account.
Mortal Sin crashed and now the save is corrupted. Is there a backup?
There is no built-in rotation, so no real backup exists. Steam Cloud keeps one version, which can be the corrupted one if the crash interrupted a write. Copy the folder to another drive occasionally if a long run matters to you.
