Galaxy Guardian

The galaxy is in danger. Armadas of hostile aliens invaded without warning and they want to enslave all the planets. The Guardian, an orbital combat platform, is the only hope for the rescue of the humanity. The Guardian is equipped with such combat systems as impulse lasers, beam guns, plasma guns, gravitational beams and rocket launchers. All these weapons allow to conduct an effective battle against any invader ships. A special shield, created by the force field generators, provides reliable protection against enemy lasers. But only a skilled orbital border guard can protect the galaxy. Check if you can do it.
