Verhaallijn

You are the only hope as Rogue Asteroids have been spotted heading towards Earth. The experimental fleet of "Orbital Defense Force Vehicles" and weapons (pea shooter, rapid shot, double shot, etc) are at your fingertips. The Computron 9000 is your state of the Art Flight Computer (512kb of data storage) will deliver information through "floppy disks" that you unlock alongside Special Weapons and additional Ships. Collect "coins" for a higher score and "energy capsules" to power up the Special Weapons quicker. Aliens and unusual Space Creatures will stand in your way through the treacherous levels. Watch out for other surprises that can "blind side you" in the vacuum of space. Oh, by the way, do you need practice flying your ship? There is a training mode you can use to try out each of the ships as you unlock them throughout your journey. Don't forget to watch for hints as you "save" the Earth from imminent danger.
