The idea of the game is that alien space craft are using the Black Hole to gain entrance to other galaxies. Unfortunately their intent is destructive, hence your task is to inflict as much damage on them as you possibly can.

You have two weapons, the Postive and Negative Ion gun, and a large Neutron Blaster. The large scale advertising campaign that Quest have launched for this program seems to suggest some amazing graphics. Yes, the graphics are good, but personally, I found the 2D effect rather confusing because it just doesn't look right. However, all in all, not a bad piece of software.
