Now some of the hackers seem to be trying to keep it lower key. Using only a proximity detector, auto spin/center and chest aim to kill you. I identified at least 3 people in a single game doing just that. You can tell from the killcams when you're jumping around they and they are dead center on you even when they are reloading and then firing.
I don't know what you're going to do Crytek, but wow after a week of playing and I'm totally discouraged.
