Dead Space 3 and Origin
Dead Space 3 and Origin
You're thinking about revisiting Dead Space and exploring Classic mode. It's possible you can load your old save from your PC if your Origin account is connected to your Xbox Live account, even though your PSN account is linked. However, Origin might not automatically recognize that you've already completed the game once. Sharing a completed save file with another player could be a good way to unlock Classic mode.
This involves connecting the PSN account to unlock a mode or transfer another player's save file.
