Comet Combat

Mysterious black portals have started appearing all across the galaxy. These portals are allowing hostile planets to invade. 

As a member of the Comet Defense Force (CDF), you have been ordered to knock all enemy planets out of the area.  

Be careful, as there have been reports of giant planets coming through these portals...
