I just want to know why? I know Crytek decided to do this, but why? this means if my ps3 corrupts.....thats it! everythings gone, and i'm not paying £40 for PS+ just to upload my game save, your game is awesome in every way i just want to know why you did this Crytek

They put locks on to stop cheating. I agree though, it svcks. I don't want to subscribe to PlayStation Plus, even for £11.99 for 90 days because they never put anything up there that appeals to me. But if my PS3 goes, i'm screwed.
Most likely if my PS3 shows signs of it about to go to the great big console heaven, i'll take a quick Plus subscription out.
