MaddenKang1234 summed this up perfectly on page 2.
There's no aimbot, no cheating or glitching. He had a wicked bit of luck. We've all had lucky shots have we not!?!?
The way the guy explains it in the video is EXACTLY what happened. He was baffled himself it has happened, so has spent alot of time trying to figure it out and he has.
Also Human, you said he put guys in last stand on page 1, that cannot be the case because then they would have had to kill themselves and it would show up like that on the left when they died.
I thought that he shot more than two people in the tunnel and put them in last stand, and then at the presise moment he got the other collaterial, they died.
I would leave him alone cause he is a much better player than u i guess maybe he didnt use hacks i think he didnt he is just that good cause he didnt believe it him self.
