[quote][b]Posted by:[/b] Sliding Ghost Just look at CE's AI. The marines berserked when they were about to die, the chain gunners threw their fists into the air when the Hog got decent height. All the base Covies sans Hunters tried to get the stuck plasma grenade off of them or responded to being stuck by a dozen needles. The Elites pointed, the Grunts and sword Elites stalked, the Grunts slept, the Hunters slept, and the AI would revert to casual patrols if the action died down. Halo 4 is probably the closest right now, but it's hindered by the lack of characterization. Elites ought to speak in English or translated so they don't look like a bunch of idiots. Marines need to speak more clearly and show a little more ferocity in combat (like the marine who blows himself and the Knight with a grenade).[/quote] I was wondering what felt 'off' about Halo 4's AI, and I think you just nailed it. They don't have personality, and adding to what you said it's also because of the small pool of animations - headshot a Sangheili and it will usually fall the same way, a charging Sangheili will always come at you with that same gait. Maybe it was the same in the other games, but post-CE the ragdoll physics made sure every enemy died differently and it did feel like the AI had more life.
