"Fasten your seatbelt... you're the pilot defending the sovereignity of your planet. Don't blink - you might miss one of the alien vessels.

Fly over your planet, protecting your comrades from alien ships trying to infiltrate your culture. Use the joystick to aim your gunsight and press button 4 to release your missiles toward the aliens. You only have 60 seconds to prevent as many enemy craft as possible from getting through.

In a two player game, you are both protecting the planet. The action builds as you compete to destroy the aliens!

Every few seconds, an enemy Command Ship will signal his presence and appear. If you destroy him, the planet's rotation speeds up, you gunsight will get larger for 5 seconds, and you will receive double points for any other alien ships destroyed.

A bonus of 20 seconds is awarded for each 10,000 points scored. An additional ship (up to four) will come into view. However, your aim will have to improve after each bonus because the ships will become more difficult to hit."

The Vectrex version is an excellent conversion of the Arcade game Starhawk created in 1977 by Cinematronics!
