Watched demos.
First demo doesnt show anything, only his death. In second demo pure aimbot, all kills were headshots only and the most interesting part about wallhack is when he stops at door like waiting for someone to come! T passes by, he runs out then turns to run back after T and gets a headshot. Could be if im wrong and if i remember correctly, SH server had no-recoil hero or something, and crosshair could be moving because of crazy sprays he did there. Thats my opinion!
