This is a space arcade game similar in its initial screen to Harrier or Penetrator, but you are in for a surprise. As the program loads you are presented with a colourful title page and catchy tune. A nice touch, I thought.
After skimming the alien planet surface and destroying everything in sight, you have to guide your ship into the depths of a volcano crater past mines, sharks and other nasties to the final battle on the fourth screen against Zug's mothership and her attendant tie fighters.
The game is difficult, but is compatible with the PASE joystick which may help. Using the keyboard I found I could only operate keys singly which can be a little frustrating.
The options mean that the player can control the degree of difficulty to a fine degree. Thus you can tune the game to score heavily in your favourite sections and ease your problems elsewhere.
This is a game which needs a lot of practice, but it is addictive and should appeal to all games players whatever their ability.
