This is a hard case. my gut says he has hacks, but at the same time there is no nail in the coffin moment in the demo. Alot of his kills could be attributed to sound, and knowledge of the map. The 32nd kill on you as a invisable off radar Vaga is hard to explain on the other hand. He does stop in the passage when he hears you teleport to your resting place, but to turn the corner and bead in on you like that is not normal. I could see where he could guess by sound that you were there, but to turn the corner with no Lace, and not using a flashlight and pop you in the head is a bit much. Some of the other kills he seems to prefire, and often he seems to look at people through walls and at times ignore them. Whenever he goes to defuse a bomb he always seems to keep the person in his field of view and doesn't look around like I think most peope would. I personally would not hang my hat on him hacking vs being very good, and having great sound setup.
