I have seen some odd stuff going on too, like getting shot twice and being dead although at full health. Or emptying an entire into a guys head and him not taking any damage but then killing me with one or two shots. Close range with a shotgun one to two shots is understandable, but not 20+ yards away and with an auto rifle. It's just sad the number of people that can't play competitive multiplayer without hacking. As for the fact of how short a time the beta has been out, CoD Ghosts hacks were made before launch of the game, so it's possible very sad though.
