Ive been really lucky in not losing a save file, most on the ps3 can be backed uped, some like RE5 can't. However the worst was not my fault, it was MW2 and it was my online profile that got hacked, me and 2 friends joined into this match that was hacked with super speed and jump. Before i could quit i got kicked. Thought nothing of it, invited my friends and went on our way. Little did we know we lost everything, emblems, titles, gun attachments, all 3 of us. A years worth of online playing, I was lvl 70 10th prestige, 27 days worth in total of online play gone in less than 10-20 seconds. Im actually surprised my controller didnt go smashing on the ground, i few controllers met there end playing MW2 (BTW i have hardwood floors), so no coming back from rage. Ive had dreams of doing saw type things to that psn user.
