The XXII century. Our Earth is in danger. The invaders want to capture it and make their colony.
For a long time the Earth was covered with a protective sphere. But the invaders have invented new weapons to destroy the protective sphere.
The only chance to protect the Earth is to use a spacefighter of new generation.
But who will be a pilot on the board this spacefighter?

This space-shooter is based upon the classical Invaders/Galaxian idea. You have to liberate your planet system from the alien invasion using your spacefighter. Player can obtain various extra-weapons and special abilities by destroying enemy cyborgs, fighters and motherships. Each planet has its own cyborg types and an unique powerful boss at the last level. Additional planet systems could be downloaded from the Internet.
