Your not aiming properly. Secondly, when people are moving and shooting back at you the game is different. I would say that having to lead slightly and still win the pistol fight makes up for the (slight) auto-aim in the game. H2 and H3 are much worse and there is no reason for these vids...
LOL. Why don`t you actually put the reticle directly on his head. Its to the side with just a bit touching his head. Thats why you only get a bit hitting. Extremely dumb video.
