City 20 is a sandbox survival game set in a quarantined, soviet-inspired nuclear city, decades after a radioactive leak left its inhabitants to starve behind sealed walls. As one of the survivors, players must adapt, trade, steal, or fight to endure, but the city remembers every action they take. Unlike traditional survival games, City 20 is driven by a procedural storyteller and a living society. NPCs follow daily routines, factions pursue their own agendas, and reputation systems shape how the world responds. Every choice ripples across three core aspects: - Environment (flora, fauna, hazards) - Society (NPC relationships, faction tensions) - Storylines (emergent narratives with long-term consequences) Alongside survival, players gradually uncover the truth behind the accident that sealed City 20. While this mystery is only partially accessible during Early Access, it will become a central narrative thread leading to the game’s ultimate ending in full release. Our vision is to create a survival sandbox that feels both endlessly replayable and deeply narrative, where players don’t just survive, but actively shape the fate of a reactive world.
