Official description

Rygot and Ixaban, the Alpha Necronis solar system's two inhabited planets, have been rivals for 600 years. What neither of the planets knew was that a third party-an alien race-has been orchestrating the rivalry in order to gain control of the system. Representing either of the newly aligned planets, you'll pilot a spacecraft through eight massive worlds in an attempt to do away with the new enemy. Enjoy four unique modes of play, awesome top-down perspective, and fantastic graphics in this action-packed battle.
