Play as Bart as he tries to thwart the plans of the evil space mutants. Collect the ingredients that the space mutants need so they can't build their machine. Only you can see them using your x-ray glasses. Also at your disposal are handy things like spraypaint, your trust slingshot and skateboard. If you can find enough proof of the space mutants your family will help you out with bosses like Nelson the bully and Sideshow Bob. So get out there and save Springfield!
