In 2719, the world is a desolation of irradiated ruins and perpetually cloudy skies, where once-vibrant cities are now skeletons of concrete and steel, corroded by radiation and swallowed by mutated vegetation. The air is thick with ash and toxins, making outdoor survival impossible without specialized clothing. The few habitable areas are pockets of misery, where humanity struggles for survival in underground shelters, dependent on decaying technology to filter the air and purify what little water remains. Mutants, the result of generations of radiation exposure, roam the wastelands, while small factions fight over scarce resources. Hope for reconstruction is all but extinguished, replaced by a basic instinct for survival in a world that seems doomed to a slow, agonizing extinction.
