A sudden acid rain plunges the once-glorious Liberty City into the abyss. Water supplies are contaminated, resources become scarce, and social order collapses completely within just a few days. The rich who once stood high above everyone else are reduced to beggars, while those struggling to survive at the bottom of society may rise to the top overnight. Three hours before the apocalypse arrives, deliveryman Jack Morrison unexpectedly receives a mysterious *Doomsday Gift Pack*—infinite supplies, an enhanced physique, weapons and equipment, everything he could possibly need. While everyone else is still killing each other over half a bottle of mineral water, he has already begun planning his own apocalyptic empire. Here, women are tradable resources, power is earned with fists and food, and loyalty is the cheapest luxury of all. Jack Morrison watches the collapse of human nature with cold eyes while personally rewriting the rules of the new world. He doesn't save the world. He doesn't pity the weak. He intends to become the apex predator at the very top of the apocalyptic food chain. Starting from the underground parking garage of Oakwood Apartments, he gradually recruits allies, eliminates enemies, and absorbs rival factions, building his own absolute order upon the ruins of civilization. When civilization falls, who will become the true king? There is only one answer— **The strongest.**
