This game was awesome. I got it for free, but it was still one of my favorite xbox games. It had a really long single player, although the story line wasn't amazing, and a great multiplayer. I would recommend this game to anyone who loves shooters. I love all the weapons and levels, although the game does get really hard towards the end. Multiplayer is really fun, as it is a lot like a robot halo. I never got to play it on live, but i'm sure it would be a blast. If you're looking for a great, cheap game, I would definitely pick this one up.
