I will say the AI has greatly improved over last time. In one particularly nasty part, I slaughtered a bunch of Flood beasts with this energy sword thing (pretty effective, with only 1 swipe to kill). When I got to the last one, he seemed to know his fate, so he kept running away from me, while I chased him. Little did I think the AI would be smart enough to have him run into a shaded corner where 5 of them waited in the dark for me. I was boned.
