Not so blatant wallhack but enough to prove it;
-27:16:59 you allign your crosshair exactly with the player's position and prefire him although he is behind the box, not in front of it. He gets killed few miliseconds before your shot but, still, it was meant to hit him. First sucpicious moment.
-28:14:01 you aim at an enemy, who is hiding behind A boxes. That can be normal but, you follow him behind the box for the rest of your movement, until you finally kill him. You actually pause and change your movement, while alligning your crosshair at his head, which makes it obvious you spotted him behind the box. It's subconscious reaction and it unfortunately busts you. Second sucpicious moment and a fatal mistake in my opinion. In addition to that, your movement is broken and terrible.
