I don't know who started this meme, but when people spoke of FEAR's ai, they usually meant the movement and co-ordination of the enemy, not what they were calling out. Fear's ai was good because the enemy was unpredictable, tried to flank you, surround you etc. I remember one time fighting a squad, thinking I've killed all of them and continuing down the level, only for 1 enemy to pop out behind me, having circled around several corridors to do so. That's what made Fear's ai memorable, not the silly radio chatter.I forget which channel it was, but I drunkenly watched a retrospective within the last year that described how the excellent F.E.A.R. AI was actually well scripted encounters in very established environments.First FEAR is still almost unsurpassed in terms of enemy' AI. That's 16 years of gaming progress for you.I remember F.E.A.R. had some good AI.
That and contextual enemy voice chatter to make it seem like the AI understood their surroundings. You're behind a couch, the AI will say "behind the couch!" which makes the AI seem more like a real human being that understands where you are in relation to the actual surroundings and is communicating with the other AI. When in reality it's just a script that's said if player is close to X object and X object is between player and enemies then play dialogue "he's behind the X" to match. Good for immersion, very well executed, but it's not impressive in terms of game AI.
