Well, this can be a very chaotic game!  The creature noises are very entertaining, the weapons are pretty good, the graphics are really cool, there are a lot of boards, etc.  The reason I gave this game a 4 is because the first-person character movement is odd.  You have to manuever the yellow buttons while you're steering; otherwise your character will just look around, which can be cool, but it can also be hard on my hands after a while.
