Set in the near future, most of Earth's land has been disintegrated in the chaos of the Anti-matter War. This real-time strategy game portrays the Colonies' Allied Force - the Metal Marines - in their epic struggle against General Zorgeuf and the Imperial Federation, who are bent on world domination. Commanding the Metal Marines across a series of battles, the player must strategically allocate resources, ready supplies, manage funds and move troops in an effort to outwit and outmove the opponent.
The real-time battle system rewards split-second decisions and adaptability in the struggle for military superiority. Unlike most turn-based strategy games, Metal Marines engrosses the player in a fast-paced and frantic battle in which both sides advance simultaneously. A constant eye must be kept on enemy movements to maintain a formidable defense and not miss the perfect chance to strike. Strategic foresight and quick judgment hold the key to victory.
