This is one strange game! I never managed to fully understand what is going on but here is what I think it is. The galaxy is under attack by a force. I am not sure if it is your side or the other. BUT, you are a pilot and you choose to which system go and attack with a beautiful impressive map. You fight the battles as a fighter pilot in space and in the air above planets. You fight asteroids, enemy fighters, robots I think, some land defences etc. It is a 3D game in the fighting part. Thing of Afterburner but better. Very strange game. Great graphics and sounds, all digitized. Also very good intro music. It has a special place for me since it was one of the first only colour games that I played on my ST on a large TV. :-)
