The high command has come up with a plan to end the war with the Kalgresh once and for all. Powerful super weapons are now being developed. Once deployed these weapons will allow the Terran fleet to defeat the Kalgresh once and for all. These weapons will require a large number of energy crystals for their construction. Energy crystal bearing asteroids (crystoids) have been located in a large asteroid field near Kalgresh space. Your mission is to harvest as many energy crystals as possible while fighting off enemy fighters. Features an infinite scrolling playfield for extended action.
