You command a group of well-armed soldiers through a series of missions, from infiltrating a drug lord's mansion to assassinating the leader of a coup. The game proceeds in real-time, but you can pause the action at any time to give orders for your soldiers to move or attack. Your units can pilot one of three specialized mechs: Attacker, Defender, or Sniper, and your squad leader Reiko has an exclusive Commander mech. Each mech has a special move in addition to attacking or defending, such as the Defender's Search, which reveals a small area of the map from the fog of war.
