In the beginning of the 22nd Century, nuclear war has devastated the Earth and turned it into a wasteland. The few survivors gather and raise the city-state Setos, and while planning a revival for mankind, meet the mutant tribe, "ATMAN".
The world has been laid waste by a nuclear holocaust. At the beginning of the 22nd century, a small number of people have survived and have re-established a city called SETOS where they are trying to revive human civilization. However, 90% of the planet is considered uninhabitable and a mutant tribe called ATMAN is terrorizing the planet. The ATMAN can only survive in the opposite environment from that needed by humans. To ensure their survival, the ATMAN must eliminate the human race and destroy the GEODEKA base, built by the KAROAN, that can guarantee the continued existence of the planet.—MediaCorp
