Somewhere deep in the future our Galaxy is at war. On the nearby planet of Neptune, forces of evil have initiated their new plans to invade the Earth. By accelerating sub-atomic particles around a tubular shaped circuit known as The Torus, they are developing a race of Super Warriors. Together with advanced genetic engineering, this central birthing canal is capable of producing an army of lethal genetically mutated insects. Nitrous Oxide, a pollutant by-product emitted inside The Torus, provides a high octane fuel for your Tunnel Runner, but unfortunately it also provides the perfect breeding environment for the secretly incubating species.
