This game makes you captain of a flying space vessel. You need to destroy all the asteroids in each level to clear it. Up and down will move your station around on the screen. The left and right arrow keys will rotate your spaceship, which controls which way it aims. To attack, push the X key. If you are surrounded by lots of asteroids, push the space bar to detonate a plasma bomb. You only have a few of these bombs, so use them wisely. Look on the left side of the screen, where you can see your shield. If you run out of shields, the game ends.
