Asteroids are a real threat to the well-being of the planet earth. If you do not believe me, just ask the dinosaurs. Finally, however, they have a sure-fire way of preventing an all-out asteroid attack on the planet earth - that sure-fire way is YOU! You have been given a ship and it is your job to get out there and destroy the asteroids. When you blow them up, you will find plenty of power ups to get you through the game intact. In order to destroy the asteroids, you have to use the arrow keys to maneuver the ship (keep in mind, when you enter the left side of the screen you will come out on the right). Shoot with the space bar. Good luck and don't die!
