Yes, your progress from the demo can be carried over to the full version of the game. If you wish to do so, be sure to install the full game on the same account or console as when you played the demo. Please note that trophies and achievements are not present in the demo version.
When launching the full game on PlayStation®4, PlayStation®5, Nintendo Switch™, or Microsoft Store, a screen will pop up asking for confirmation about transferring your save data.
The Steam version will automatically carry over your save from the demo. Should you wish to start the game with a new save file, be sure to delete the existing save data from the title menu.
While it's possible to transfer your progress from the demo on PlayStation®4 to the full game on PlayStation®5, or Nintendo Switch to Nintendo Switch™ 2, no cross-platform data transfer option exists for other platforms.
