"IN THE ZONE". Man the group I was with was moving around, waiting for everyone to reload before killing that last guy, shields planted, granades placed to watch our backs, chainsaw killings where you could barely see anything with all the blood and guts on the screen..............."disc error" message comes up. F*%K!!!!!!!!! I hope those guys made it. I didn't get a ton of achievements *sniff*.
