i've watched a few demos of this guy. some guys, i look and i'm just like man it's hard to tell but there's no way he's legit. this isn't one of those guys. everything i'm seeing, i've done myself. and i don't hack. he's a very good player with excellent mouse control and recoil knowledge. the krieg kill on shotty was luck. that's all there is to it. his crosshair was there, he strafed out, shot, and got lucky. after that he gets a nice snap headshot (happens, part skill and part luck), and then a headshot streak getting headshots early in bursts with rifles. nothing to me indicates anything unnatural.
