With Stadia shutting down in January , folks are understandably worried about their save game files. Those who play Cyberpunk 2077 and want to continue playing their game on another platform, need only do the following using Google Takeout, per CDPR.

If you own a game copy on a supported console platform, you can use cross-progression on any of the PC platforms and sync it with your GOG account to transfer your progress to a console. Once you have completed the final step, start Cyberpunk 2077 on your PC. Make sure that you are logged in in the REDlauncher as this is the account used to store your cross-platform saves. Make sure the cross-platform saves are enabled in the in-game Settings and then load the latest save file from Stadia (or any other that you want to copy). Then, save the game again. This save file should be synced with the cloud and appear on your console if you’re logged in to the same GOG account. Best of luck!
