Where Are Mortal Shell II Save Files Located?
Mortal Shell II saves under a MortalShell2 folder in Local AppData, a different root than the first game's Documents tree.
Last updated
Mortal Shell II stores saves at %LOCALAPPDATA%\MortalShell2\Saved\SaveGames, with graphics and input settings in the Saved\Config\Windows sibling. The folder name compresses to MortalShell2 with no space, so searches for the roman numeral or the spaced title miss it.
The bigger trap is the predecessor. The first Mortal Shell keeps everything in Documents\My Games\MortalShell\Dungeonhaven, and guides written for it send sequel players to a folder that will always look empty. The two games share a name and nothing else. Steam Cloud is listed for app ID 2584270, so when restoring a manual backup, pause sync first or the older cloud copy can win.
Where Mortal Shell II stores this, by platform
%LOCALAPPDATA%\MortalShell2\Saved\SaveGames
Progress and character slots. Note there is no space and no roman numeral in the folder name. Copy the whole Saved folder with the game closed to keep saves and config aligned.
%LOCALAPPDATA%\MortalShell2\Saved\Config\Windows
Graphics and input settings. Edit with the game closed. A corrupted config here is the usual cause of launch failures, and deleting it regenerates defaults.
~/.local/share/Steam/steamapps/compatdata/2584270/pfx/drive_c/users/steamuser/AppData/Local/MortalShell2/Saved
Steam Deck and Linux run the Windows build through Proton, so the same MortalShell2 tree lives inside the prefix for app ID 2584270.
Frequently asked questions
Why is my Mortal Shell II save folder empty?
You are probably in the first game's folder. Mortal Shell puts saves in Documents\My Games\MortalShell\Dungeonhaven, while the sequel uses %LOCALAPPDATA%\MortalShell2\Saved\SaveGames. Check both roots and trust whichever holds recent files.
How do I back up Mortal Shell II saves?
Close the game and copy the whole %LOCALAPPDATA%\MortalShell2\Saved folder. It holds the SaveGames tree plus your settings in one move. Sort by date modified to confirm the game writes there after your latest session.
Does Mortal Shell II sync saves through Steam Cloud?
Yes, cloud sync is listed for app 2584270. That helps across machines, but it can overwrite a manual restore with an older copy. Pause sync while transplanting files and keep a spare until your run loads.
