This game could be great but because aiming a weapon is so bad and because you can't save your game,I can't recommend it
Halo has to be the gold standard for X-box games. That being said, this game could have been great, maybe even as good as Halo. However for 2 reasons I wouldn't recommend it.
1. When you are trying to shoot a weapon, the ability to hold your aim steady is very difficult. Head shots are the goal for quick kills but it's almost impossible. This gets very frustrating.
2. You can't save your game! As you play through a level you eventually come to a check point you can come back to which is fine. If you want to quit mid-level or if you get to a difficult spot and want to save before you attempt it, you are out of luck.
