Saves

Quit from the game's main menu, or F9 then Quit game, so a save in progress is never cut short.

Backup

One zip with your profiles, the game's options, settings.ini and F12 screenshots. Restoring a backup replaces all of them in this browser. Profiles from the PC game restore too, beside the ones here: zip the folder %LOCALAPPDATA%\NFS Underground 2, or pick a profile's own file in it.
