It didn't look like hacks to me. Only one questionable part was at the windows when I kept the trigger down around the corner, I heard that guy and had a general direction of where he was which is the reason I ran right past him. Where else was I hacking at in the video? Where I shot the guy with the shotgun who was using an auto shotty on my teammate that was looking at him therefore allowing me to see on the minimap? The beginning of the video looks really suspicious but I had seen that guy on the other side of the box, he had just rescued the hosties and won the round. I was getting alot of lucky headshots just spraying.

Edit: Even the part where squats says something about me prefiring, you can see that I was around the corner looking down the hallway before I fired.
