I joined specs to watch this guy cause his kills seemed a bit too fast considering his positions.
I managed to record 3 kills that look odd. Then Chron joined specs and as soon as he came this guy takes cover behind the wall, stands there for few seconds and all of a sudden he can't hit a damn thing.
I think he was using an aimbot and then turned it off (possibly left autoshoot, hard to tell since his ping was going from 50 to 120).
