The surface is uninhabited. In 2035, the "Great Blackout" wiped civilization from the face of the earth. Electromagnetic pulses destroyed global power grids, and humanity perished not from radiation, but from chaos, famine, and barbarism. To survive the collapse, Genesis Holdings built state-of-the-art underground bunkers. The year is 2041. You are Zero, an Alpha specimen. After nearly ten years in crumbling cryostasis, you awaken in the depths of the Eden-4 bunker. The bad news? The survival rate in cryopods is only 5%. You are the last surviving human in this complex. The good news? Your body is the key to humanity's future, and the "Repopulation Protocol" has officially been activated.
