Only partway through it at this point, but so far the AI has been noticeably retarded at times and noticeably brilliant at others.
Tanks blowing up buildings between me and them to get a clear shot is a nice touch. Enemies standing in a stairwell looking in the opposite direction despite me tromping around loudly uncloaked ~10 feet directly behind them is not.
Pincer moves in the forest is pretty cool. Not coming upstairs when I am blowing away your comrades quite loudly with a shotgun is not.
Using your emplaced guns to blow away my cover as I'm waiting for my energy to recharge is refreshing. Not leaving your emplaced gun when I huck a grenade in there is not.
It's like for every high, there has to be a low.
One cool moment so far: Got into it uncloaked with a bunch of KPA in the coconut field right after Prophet got nailed by that alien doodad. Like ~5 soldiers plus they called in a hummer, which parked right next to an empty one in their little encampment. I ran into one of the huts, which began to disintegrate around me, so in a panic I lobbed a grenade under the occupied hummer, ran out back, and dove behind a fence.
*ka BOOM*
Grenade -> Occupied Hummer -> Unonccupied Hummer -> Fuel Barrel was the order of explosions. Took out a couple buildings and pretty much all the resistance. Not bad mileage from one grenade.
Was also trading fire with some KPA in the village before grabbing CIA lady (first hostage), not noticing they had taken cover in the *gas station* of all places, and while attempting to headshot some guy in the doorway, I hit the pump one too many times and the whole damn building lit up.
Some cool moments, to be sure. I have a feeling I'll be back to this thread though when I get to the last 1/4 of the game, as it sounds like they reeeeeely screwed the pooch from the reviews.
