A great Xbox Live Arcade Game, for being a free one.
Gameplay: Easy. All you do is move around and shoot stuff, along with using special weapons and in multiplayer, attaching to your friend's ship. Pretty simple huh?
Graphics: Good for an arcade game, but nothing to Gears of War and The Darkness.
Sound: New version of game music? I don't like it, but hey, thats why we have MP3 players, right?
All in all, great game, great multiplayer, great fun. Enjoy.
