No Rules Get Phat  Gameboy Advance

Play as One Eye Jack, a skate fiend and leader of the No Rules posse who must stop an alien invasion of his local hangouts. To defeat the aliens you must board like a pro and be a deadeye shot with your slingshot and alien slime gun. You must also mix and scratch with your portable turntable to melt the aliens, then bust out tricks such as a double ollie, a 360, and a hand plant. There are five worlds to explore, including Colbutt Mountain and the Cocoa Soul Puffies cereal factory, and more than five enemies per world. You will battle aliens, wolves, polar bears, alligators, rats, and bats.
