I'm very sorry NightStalker666. I feel your pain, that happens to me with Assassin's Creed at 80% of completion
. Autosave and only one slot, This is the most big Sh@%!!!! Now i am afraid to play too, i played 25 hours on FUEL and I am far from having finished!
Yesterday i bought a memory card on the web,I'm waiting for it. I think it's possible to create a backup of the saving files on the official microsoft memory card. My idea is to create a backup once per day. It's better to lose one ''gaming" day instead of the whole game.
