The Antimatter Cold War has left Earth ruined as the stockpiled AM weapons of various nations were triggered in a chain effect, vaporizing large portions of the Earth. The once great continents have been drastically changed into thousands of tiny islands and various cities have washed into the oceans. During this turmoil, Zorgeuf the Great rushes to conquer the bewildered world along with a troop of commanders and declares the Earth Empire. The only hope to defeat him lies from without Earth, as the Colonial Forces send a command carrier from the major orbital base. With so many armies gone, the ground infantry unit has been replaced by the Metal Marine, a fifty foot armored robot that can be sent into battle for attack or defense. From their respective Command Center, each side in the conflict will need to direct the placement of facilities on the ground to defend against enemy attack, manage resources and successfully strike the enemy.
