Game Description:Every single day, thousands of people perish at the hands of a ruthless alien race called ''Diadora.'' Those who survive take refuge under the earth's surface, attempting to escape the attack of the alien invaders. The remaining government council decides the best defense is an unstoppable offense, and orders immediate counterattack. The primary mission, codenamed ''Counter Force,'' is to reclaim the surface of the earth using three prototype robots. Investigate the alien's weaknesses as you experience the fast and frantic action. Load up with powerful weapons and upgrade your robot to face twelve different enemy types and five different bosses.
