===Attacking the Alliens===
Once you select your skill level, outer space forms on the display. Incubators and spores randomly appear. (Note: The number of each depends on the selected skill level.) Colored numbers appear inside the incubators and start counting down to zero. When an incubator reaches zero, two or three spores or an alien hatch, depending on the skill level you selected and the stardate. The stardates in which attacking aliens hatch from the incubators are shown here:

Using the arrow keys or the remote controllers, maneuver your ship and begin firing on the spores and aliens. Plan your attack carefully and you'll be able to destroy a line of spores with repeated fire. When four spores cluster together forming a square, music alerts you that a large red alien has appeared. Skilled maneuvering will get you to the alien before it gets to your ship!
Each time you hit a spore, you get 50 points. A destroyed alien increases your score by 100 points, as shown here:

When you are in a stardate where aliens emerge from the incubators, mount your best attack. All hits are doubled! If your attack is extremely skillful and you score 500000 points, the score display rolls over and restarts at 000000. Be sure to add both scores together when calculating your total score.
At the beginning of Stardate 1, you command ten ships. Each time your ship is engulfed by an alien, your ship supply decreases by one. Your attack continues when a new ship appears. A stardate is completed when you have destroyed all the aliens and there are less than ten spores remaining. At this time, bonus points (determined by the level of difficulty and the stardate of the game) are added to your score for the remaining spores. Also, one ship is added to your supply. As the stardates increase, so must your ability to carry out a strategic attack. (''Note'': To start the current game over with the same level of difficulty, you can press '''SHIFT R''' (REDO) at any time during the game.)
When the aliens deplete your ship supply, the game is over. Your score appears in the upper right-hand corner of the screen. To play another game on the same level, press '''SHIFT R''' (REDO). To play again with a different level of difficulty, press '''SHIFT Z''' (BACK) to return to the selection list. Next game, see if you can increase your score, advance your skill level, spend more stardates in space, or do all three!
To deactivate all systems when you have completed your mission, press '''SHIFT Q''' (QUIT) to return to the master screen.
