In the year 2125, a nuclear war wiped humanity off the face of the earth. The species' only hope for survival is the Factory, a complex built before the apocalypse. It's purpose is to birth and supply a new generation of cloned humans. The Factory was a success, and a thousand years after humanity's extinction they have been reborn. Under the leadership of Great Grandpa, the first born from the Factory, humanity will once again spread across the Earth.
