The virus has tightened up my wallet so I have to wait for the next sale to buy the game and was wondering what will be preserved between steam backups and the shift system when it comes to the science event skins, in game acquired skins, guns in the vault, campaign progress. Due to the DRM I can’t copy paste the save files myself and 2k implies that you need to buy the game to keep your progress from being nuked by denuvo.
AFAIK so along as you don’t delete the save games folder you should retain all progress. Surprised you can’t make backup copies of the files yourself - a lot of other folks are doing that with the paid version of the game.
Note that cosmetic items are in a single separate file (profile.sav) to the save game files for each character you created.
