I was playing on Assassins Creed earlier, just normal right. My Xbox is on a shelf that I rest my feet on right?
So half way through my foot twitched, kicking my 360 off the shelf :O! It fell off, disconnected and turned the entire thing off with it making a nasty noise! I panic, pick it up and put it back on. Take the disc out, NO scratches!
My mate simply moved his Xbox with it on, destroyed his disk!
