Qewpi

1st clip: He tests his recoil twice, opens the Aptitude menu, changes a few settings while tap-firing at the bomb, then tests his recoil again. 2nd clip: He breaks the window glass, which is a normal setup, but at 00:16 he stops preparing site after noticing a player approaching and immediately holds the angle instead. 3rd clip: At 00:08, his crosshair drifts onto the player's head, he slightly readjusts, and then fires before the player is visibly peeking. The rest of the clip isn't as noticeable, but there's still quite a bit of crosshair lining up in my opinion. 4th clip: A lot of tracking and staring through walls. 5th clip: He notices someone approaching, then tries to play it off once they move away. Later in the clip, he accidentally tracks a player directly above him through the floor. 6th clip: More examples of crosshair lining up and looking through walls. 7th clip: It doesn't seem like he's been cheating or even playing for very long. He looks through a reinforced wall before quickly realizing what he just did. 8th clip: Based on the first clip, we know he uses Aptitude. Here, it looks like his triggerbot may have activated when his teammate walked in front of him, even though there wasn't any reason for him to shoot.
