I love FEAR as much as the next guy, but the AI complexity is overblown by the fact they broadcast everything over radio and you say to yourself "Wow, they're working as le team!" when every other AI does pretty much the same thing except they don't actively tell you they're doing it.
No, most FPS AIs don't do even half of what the F.E.A.R. AI does, and them talking to one another isn't making the AI overrated, it's there to make sure you are aware that the AI is advanced and is doing what it is doing. Without the barks from the soldiers the player would have no real way of telling what they are up to, if it is dynamic or entirely faked, most games get away with minuscule AI partly because they are more opaque. No wonder most devs don't even bother with spending much money on AI when most of gamers are as retarded as you are, making them move forward, shoot at player, take cover if you feel very ambitious really is enough for you lot.
