Wait for the applet and sounds to finish loading, this may take a minute or two. The game screen will show "Game Over - 'S' to Start" once everything is ready. In the meantime you can review the instructions below.

.Playing the Game
Use the keyboard controls described below to maneuver your ship, destroying as many asteroids as you can while avoiding collision with them. Also watch for the flying saucers armed with guided missiles.
If you warp into hyperspace, your ship will momentarily disappear then reappear on another part of the screen, gradually fading in. During this time the ship is invulnerable. Likewise, when your ship is destroyed, a new one will appear in the center of the screen. You can still maneuver and fire during this time so if you are in imminent danger, you have a couple of seconds to get out of it.
