In case you get stuck in the game and are unable to progress by using the Restart Last Checpoint option, you can use the following workaround:

Ratchet & Clank: Rift Apart features automatic backup saves at key points in the story. If your current game slot is stuck in an unplayable state, you can return to a backup save instead of starting the game over.

To do this, exit the game and go to the Ratchet & Clank: Rift Apart folder that is located inside the Windows Documents folder.

The path of the folder will look similar to this:
C:\Users\USERNAME\Documents\Ratchet & Clank - Rift Apart\

If you installed to the default path, copy and paste the line below into your file explorer. It should take you directly to where the save files are located.

%userprofile%\documents\Ratchet & Clank - Rift Apart\

In here, you will find a folder with a long number or combination of letters and numbers. That folder contains the save files and the backups.

• Backups have the same base name as the save slot with a suffix added. For example: slot0-s.save.backup01.
  
• If you do not see the backup files, go to the View tab in the folder and click the 'File name extensions' checkbox.
  
• There is a maximum of 10 backups per save slot, the backup with the lowest number is the most recent. You can confirm this by looking at the time and date the backup file was created.
  
• To restore a backup, remove the ".backupXX" extension from the filename to overwrite the normal save. So slot0-s.save.backup01 would become slot0-s.save.
  
• Each profile has its own autosave and backups. The game has a maximum of 6 profiles. Slot0 is Profile 1, Slot5 is Profile 6, etc.

Please be aware that overwriting existing save files can result in losing progress. You can backup your own save files by copying them and storing them in another folder, before overwriting any file.

You may lose some progress depending on the time between when the save was made and when you experienced an issue.
