at 6:09 when he goes to grab a weapon X appears, wich appears only if you're moving with controller instead of keyboard and at 6:20 he said that he's using mouse and keyboard, wich is obvious proof of mouse/troller glitch, wich he has been doing for the past 2 months and 20 days.
At 18:08 he kills the guy with last shot shooting him at the hips, wich is proof of increased bullet magnetism in my opinion not only by the controller added aim assist, but manualy increasing bullet magnetism throught hacking as well.
At 19:25 if you play throught this part a couple of times, especialy throught slow motion you can see that he snaps towards his opponent at exactly 19:27, when his hole pc reacts to it, his aim get's exactly at his opponent's hips, wich is indicator of aimbot, and he snaps in such a way that there is no human being on this planet that aims like that and at the same time the computer would react in such a way.
