Halo 1's AI was kinda revolutionary at the time. Also I've always thought that the AI in Reach kinda cheated. Try aiming a sniper rifle at them on Legendary and they WILL know you're aiming at them. It's uncanny levels of screen-looking lol
[Covenant] an advanced alien race made up of several species that have several advanced resources and technologies that surpass the human technology by miles. Of course it will "seem" like theyre cheating. haha
