After reviewing this with @"TripleCDawg" and Silver Smurf, it kinda looks like aimlock and aim assist @40 seconds. If you view from @36 seconds you see how he flicks and instantly locks on to the player model without hesitation. At first i thought it was luck but then i remember someone telling me that they thought he had hacks after some weird shots, so i reviewed it more thoroughly with @"TripleCDawg" and Silver Smurf and i think he may of been hacking whilst he was in the middle of breaking rules. This is just my opinion and has the possibility to be wrong, but if it is possible could a G+ please watch over it a couple of times just in case he is actually hacking. ty :3
