In the far-away place called Gadget Land, the evil Thump has stolen the Magic Gem from the King's castle! The only hope of getting the Gem back is two brave jets, Bop and Bump! Play Bop and Bump simultaneously, or Bop alone in the one player mode. Begin your journey armed only with your multi-directional boxing glove, and gather more powerful and complex weapons as you progress. These items can be purchased when you pass a shop or by punching open one of the treasure chests scattered about. But no matter what objects or weapons you obtain, Thump has an array of devices designed to challenge Bop and Bump through 12 levels of side-scrolling action!
