Hmm, I've spend a good few hours on the game now, as others have said, the enemy A.I. is quite impressive, especially with grenades. Friendly's A.I. seem to be not on par with that of the enemies though, an attempt to make the player to do more I guess. Rico have, in countless times, move into my line of fire, while I was standing still, shooting. (Although, on many online games, I have human teammates doing the same thing as well, so I guess it's not too bad, but com'on these are supposed to be professional soldiers.) And sometimes Rico with try to Rambo it by running into the middle of a fire-fight with his MG and get blasted into shredds, which left me to clean up his mess by saving his butt while exposing myself to the same threat which took him down.

But I like the game over-all.
