I am really enjoying Rage, great game! Yeah the textures are blurry close up but the art style and gun play it excellent and this has to have the best AI in a FPS! Different enemies use different attack patterns and weapons, like the mutants who jump and swing and dodge left and right and some others who take cover, blind firing whilst a heavy armoured dude moves forward with a shield or a mini-gun.
When you wound one, they will attempt to get away or try and crawl. Simply brilliant IMO
