Toward the end of the 21st Century two great powers dominated the world, a division that resulted from a 30-year war known as the War of the Hemispheres. The war came to an end with the creation of giant, indestructible mega-robots designed for military missions and balance of power. With the treaty came peace and both sides merged into one government, the New Federation. The armed forces were reduced to one single mega-robot, the MRAS-2, an 80-foot-tall Mega-Robotic-Assault-System, now used to guard the most dangerous spot on earth. The MRAS-2 now patrols the highly restricted area known as the Crosshair Zone, the site of the Toxic Tomb-a dumping ground for the most dangerous toxic waste.
