Spec'd this guy after seeing several players complained about him in chat, definitely suspect. Using M249 looked like he was just spraying but getting headshots virtually every time. Also a possible wallhack, watched him seem to follow and then fire randomly at the wall of a building, then he turned 180 and got a headshot on a player I couldn't even see.
