Every day, thousands perish. Those who survive share rumors of an alien entity called "Diadora". The survivors took refuge below the earth’s surface, narrowly escaping the alien invaders. The governing Council ordered an immediate counterattack. The primary objective codenamed: "Operation ExZeus" would reclaim the earth’s surface using 3 experimental robots. Operation ExZeus’ secondary objective is to investigate the alien war-machine’s weaknesses and defeat the mysterious "Diadora". Three freedom fighters – Sophia, Calista, and Dynamis (the leaders of a Special Squadron team) are humanity’s last hope for victory.
