An alien invasion threatens Earth and the team looking to stop it is the Kore Gang. The Kore Gang consists of the story's three protagonists: Pixie, Madboy, and dog Rex. They stumble upon an invention made by a brilliant-but-scatterbrained inventor called the Kore Suit. The Kore Gang enters the suit and uses it in hopes of stopping the invasion by the inner earth creatures. These inner earth creatures have been living deep inside the earth waiting for their chance to finally rise and take over the planet. These monsters are headed by the three Krank brothers who control a giant monster that they use to drill through the earth's crust. Players must stop the incoming invasion and save the Earth.
