The Planet Fighter

Invaders of the galaxy are destroying many planets all around however they have made a wrong choice of enemy this time, YOU. Their numbers and firepower seems much higher but it is nothing to a patriot like you who is willing to defend the motherland. You have protected your home many times before these invaders even existed and this is like a walk in the park for you but they do not know it yet.
Shoot and clear the fleets of invaders to advance and watch out for the divers. Collect the shield and protect yourself.
