The year is 2012, and humans have just found out that they're not alone in the galaxy. Not only are they not alone, but the new arrivals aren't friendly in the least. The invaders are not here to conquer - they're here to harvest. Massive walking machines consume plant, animal and mineral without distinction. Press gang-like hordes of invading ground troops herd humans into enormous mass drivers, launching them up to the invader's ships that orbit the planet, never to be seen again. Our game begins on the eve of the last day of human resistance... Or is it?
