I'm not saying that there isn't something going on, I'm just saying that its probably not cheating. Its certainly nowhere near the level of some of the cheating that I've experienced. It could be that, or it could be a bad connection, but from the video its pretty difficult to distinguish. Its fairly common for hits not to register, and then for you to die almost instantly as the game catches up. You can see that there's delay in the notifications popping up. Usually this accompanies delays in kills registering, players taking damage, etc. There's been plenty of times when I've hit someone with golden gun, and waited maybe 5 or 10 seconds for the kill to actually register. What I'm saying is that from this video you can't tell if its cheating or just regular lag.
