The object of the game is to blast a path through an asteroid field that your spaceship has stumbled into by using your unlimited supply of Photon Torpedoes (mouse to aim, X key or left-click to fire) and Neutron Bombs (Z key or Spacebar to launch) that destroy all asteroids in a single hit should you get swamped.
You start with only 5 Neutron Bombs but get an extra one for each 50,000 points earned. You may only launch one at a times.
For each Asteroid hit that you take you lose 5% shield strength. For each 5,000 points you earn you gain 1% back.
Level 1 is dead easy. Only about 2 asteroids come at you per second and most will not hit your ship.
Level 6 is pretty hard. You get 10 or more asteroids per second and many more of them are on a collision course. You'll need your Neutron Bombs and some rapid fire to avoid destruction!
Level-ups occur every 50,000 points earned.
Version 2 is a complete redesign of the menus and play field with improved game play.
