If you own a 360 and have not played this game, go out and at least rent it. It is awesomely addictive and requires true skillz to play. The learning curve for movement and shooting is a little steep, but not impossible. (I mastered it in just a couple of hours)
Storyline is a little cheesy, but there are some good cut-scenes. If anyone else has played this game, has questions or tips, or just wants to talk about it. post up!!!
