There is AA within the reticle. This isn`t a new discovery; John Howard already told us this and shared his thoughts on why this required on a console shooter.
Honestly, the number of retarded people here is amazing. Do you really think that because your reticle is red you deserved to hit all your shots, even if there is just a fraction of the opponent in the reticle? It doesn`t happen this way consistently at all, nor should it, in any of the Halo games. The point of the video is you always here people chirping about how CE has tiny auto-aim compared to 2 and 3 - obviously that`s not true.
Well... it IS auto aim because without an enemy in the way the bullet always hits center. With an enemy nearby the bullets curve, even without a red reticule. (shown in one of my vids) The real issue is how h1 has much LESS AA than the other 2 games.
