Cyberbots: Fullmetal Madness is set at the end of the 21st century, when humanity has expanded far beyond Earth and begun colonizing deep space. The Earth Force — an army of enormous mechs and their elite pilots — serves as both Earth's defense and the colonies' primary protection. Players choose from six pilots and twelve distinctive mechs for 2D combat, earning the ability to upgrade and customize their machine with new parts and weapons between fights. The story, which unfolds across battles, traces the machinations within Earth Force and the consequences of its most dangerous experimental programs — consequences that will determine the future of Earth itself.
