The Alters Save File Corrupted — How to Fix & Recover

Last verified: 2026-09-20

If The Alters says your save is corrupted or won't load, don't overwrite anything yet. Here's the exact folder to protect, how to recover from the game's own backup or Steam Cloud, and how to stop it recurring.

Quick answer

%LOCALAPPDATA%\11bitstudios\TheAlters\Steam\Saved\SaveGames\<user-id>

If The Alters says your save is corrupted or won't load, stop — don't launch back in and let it overwrite. Your saves live at %LOCALAPPDATA%\11bitstudios\TheAlters\Steam\Saved\SaveGames\<user-id>. Close the game, copy that whole folder somewhere safe first, then restore a clean copy: check the folder for the game's own backup (a .bak / .old / backup copy of the newest save) and rename it back into place, and if the local files are all bad, roll back through Steam Cloud. Verify the game files if nothing loads at all.

How to transfer your The Alters save to a new PC

Fully close The Alters — check Task Manager so no leftover process is still writing to the save while you work.
Open the save folder: press Win+R, paste %LOCALAPPDATA%\11bitstudios\TheAlters\Steam\Saved\SaveGames\<user-id>, and press Enter.
Back up EVERYTHING first: copy the entire folder to your Desktop or a USB drive. This is your undo button — do it before touching anything.
Look for the game's own backup inside that folder: a file ending in .bak / .old / .backup, or an autosave/backup subfolder. If one is newer-than-corrupt, rename the bad save out of the way and rename the backup into its place, then launch.
Roll back Steam Cloud if the local files are also bad: exit the game, turn OFF Steam Cloud sync for this game, restore your known-good local backup, launch to confirm, then re-enable sync so the GOOD save uploads (not the corrupt one).
Verify the game files (Steam: right-click the game › Properties › Installed Files › Verify integrity; Epic/Xbox have the same option) to rule out a damaged install rather than a damaged save.
Still stuck? Right-click the save folder › Properties › Previous Versions, or check Windows File History / a system restore point for an older copy from before the corruption.

Does cloud sync move it for you?

When Steam Cloud and your PC disagree you'll see a sync conflict asking which save to keep. Read the timestamps and pick the one matching your real last session. If you already picked wrong, restore the folder backup you made before letting it sync again — otherwise the corrupt or older save overwrites the cloud copy too.

Common mistakes

Overwriting before backing up. The #1 way people turn a recoverable save into a lost one — copy the whole folder first (step 3).
Letting the cloud re-sync the bad save. Disable sync (or restore before re-launching) or the corrupt file just downloads/uploads again.
Editing the save bytes by hand. In online games that can trip anti-cheat — restore from a backup or the game's own .bak instead of an external editor.
Assuming it's the save when it's the game. If nothing loads at all, verify the install and check recently added mods before writing off your save.

FAQ

Where is the The Alters save file on PC?

It's at %LOCALAPPDATA%\11bitstudios\TheAlters\Steam\Saved\SaveGames\<user-id>. Press Win+R, paste that path, and press Enter to open it. See the full The Alters save location guide for PS5/Xbox paths too.

Can I recover a corrupted The Alters save?

Often yes. Check the save folder for the game's own backup (a .bak / .old copy) you can rename back into place, and Windows Previous Versions or your Steam Cloud copy may hold a clean version. Always back up the folder before you try anything.

Why did my The Alters save get corrupted?

Usually a crash or power loss while the game was writing the file, a cloud-sync conflict resolved the wrong way, or a full/failing disk. Making a manual backup each session is the only reliable protection.

Will I get banned for restoring a The Alters save?

Restoring the game's own backup or a folder copy you made yourself is fine. Byte-editing a save with an external editor is what risks anti-cheat flags in online games — avoid that route if you play online.
