You have been sent on a mission to destroy a thermonuclear planet in the Halson galaxy full of aliens, craters and lakes!. Every so often, a spaceship appears and you enter it, taking you into space, where you shoot and dodge spaceships instead. The gameplay is too difficult though as you need to be very precise when jumping over obstacles as the aliens are swarming around you and draining your precious energy. If you like this kind of gameplay (well, I am) then it will give you many hours of great action.
The CPC uses nice graphics with bright colors (mostly purple!), although the animation suffers a lot and makes the gameplay from difficult to impossible! The sound is typical featuring a few sound effects of shooting and explotions but nothing really special.
