Game Description:Earth's population is on the verge of death. But out of the blue, an alien race, the Krellans, come to help: they teach how to colonize space, new medicinal sciences, and peace. Until the day that a single Krellan ship finds its way to the Aphelion station on the borders of colonized space with a single woman on board. But it isn't a woman: it's a shapeshifted Krellan that, through a memory scan, reveals their race's plans for conquers. All communications are jammed, and the attack soon commences: there's nothing to do but to move towards Earth, surgically destroying critical Krellan outposts in 11 4 mission campaigns, hoping to be quick enough! Will a spaceship and a tank be enough for the job? Only one way to find out.
