Asteroids surround you. Trapped far from home your embattled spaceship hurls towards its doom. You are caught in the center of a gigantic cloud of asteroids. You have no choice. You must pulverize all the asteroids in your path with you photon cannon if you are ever to save yourself and your ship. You have more than enough photon power to destroy all the asteroids you can see, but you can only fire four shots into the asteroid field at one time. You can be hit four times before your ship is finally destroyed. Every 10,000 points you score will earn you another ship.
