takes place on isometric science-fiction landscapes where all enemies have to be destroyed. So the player mans a space ship, flies around the three levels (with the ability to turn around and change the flying height) and shoots everything he sees: Besides flying enemies there are also defense stations on the ground to be dealt with. But while rocket ammo is unlimited, fuel has to be regularly refilled by landing besides a fuel pod. Three smart bombs which destroy everything on the screen help in tight situations. Every level runs on a time limit.
