From the back of the box:
Strange lights in the sky, prophecies of doom, and a threat unlike any other draw the heroes to Aston Point. In this small frontier town, the fate of the world will be decided. If the heroes and their strange new allies defeat the invaders, they must then pass through a portal to another battleground, a metal city on a far-distant world, where aliens fight desperately against death machines that threaten to overwhelm all organic life. So trade in your sword for a blaster rifle, your sling stones for a few high-explosive grenades, and see what happens when you mix magic with high technology.
