I was in a search and destroy last night and one guy had god mode, I was dead and was watching another team mates game play, he came up behind one guy aimed the shot gun right at him and fired 4 shots point blank into this guys back and did not kill him and the god mode guy turned and killed my team mate for the final kill.
in the kill cam the god mode guy didn't even get slightly injured, he finished 16/0
lately I find 1 or 2 hackers each day
