I am a new xbox 360 player,and this is probably my favorite game so far. It feels like an arcade shooter. I had a friend over and the co-op mode was a blast.Graphics are not the prettiest I have seen so far, but the gameplay is quick and fun. Picking the right weapons is critical for each mission. My only complaint is how hard the difficulty setting can get, but you have to beat levels on the most difficult to get all the weapons. And those damn spiders will not let go! All in all, great game .
