Exolon - The Continuing Adventures

Intelligence agents informed the "Earth Council" of an alien race planning to attack and destroy the Earth. Vitorc had the reputation of being a bit of a badass, so it was he who was commissioned for the job - To rid the alien planet of all the scum and save the Earth from certain doom.

Vitorc blasted his way thru 125 screens of alien slime. Its what his job was and its what he did best. He succeeded and promptly flew home...

The "Earth Council" thanked him for his efforts but wouldn't allow him to land on Earth - EVER - because of possible alien contamination.

Dejected and bemused Vitorc returned to the dreaded planet only to find that the aliens had rebuilt their cities and were preparing an army for the destruction of earth once more. Even though Earth shunned him after saving them once, Vitorc, the true hero, decided he must save the planet once again. Anyway, those damn aliens had his ship in a magnetic tractor beam powered by a huge reactor so he had to do the dirty deed !! 

Kill the baddies, blow the reactor and get off this damned planet...
