took me about 15 hrs.....here are a couple things i liked.....
Graphics
Good storyline
cool weapons
i didnt like how bullets would go through 5 ft thick walls or how u can get stuck in them....the 3 boss aliens were a joke at the end of the game all u had to do is pistol whip all of them to death.....i was expecting some huge robotic creature kind of a letdown...another thing is after u beat the game on supersoldier u should unlock some weapons for multiplayer!!!!
anyways...over all 8 of 10 for me
