Game Screen Scaling:

The screen size can be scaled by using the <Page Up> and <Page Down> keys.

Game Levels 1-6:

The game is won by destroying all Descending Enemy Fusion Weapons (Blue).  The game is lost when uncontrolled Radial Fusion is triggered by either Stable Orbital Enemy Mines (Red) or Descending Enemy Fusion Weapons (Blue).  There are 6 levels of increasing difficulty.  The bonus level is enabled after passing level 3.  Player initials, high score, total Player Ships damaged and game time are all saved at the end of a level.

Bonus Level:

Play until the Player Ship is destroyed.  Use the Player Ship beam weapons to discharge the Low and High Orbit Enemy ships before they fire their weapon.  Firing on a noncharging enemy ship will result in a feedback beam pulse that will reduce your score.  The enemy weapons will charge faster and faster over time as the bonus round continues.  Player initials, high score, Enemy Low and High Orbit Charge Speed (CSL) and CSH) for the bonus round is saved.

Stable Orbital Enemy Mines (Red) - Level 2 and Above

• If you stay too long in one orbit the mine will fire an orbital plasma weapon.

• Avoid Player Ship collision, or the mines will all fire lasers into the star and trigger runaway Radial Fusion.

Charged Yellow Orbit - Level 3 and Above
