As we've all been experiencing, I fell into a hacked lobby last night. I guess I'm somewhat lucky as only all my assault rifles got reset. Nothing else (level, challenges, perks, camos, etc.) was touched.

I'm on PS3 and my question is, is it possible to save or back up your current MW2 game so that when the day comes (and I know it will) when I get totally hacked and zapped, I can revert back to my saved game?

I've really been putting off moving to Black Ops but I have heard that it can't be hacked...yet.
