City 20

City 20 is a survival game set in a sealed city that was erased from maps. Scientists there pushed the boundaries of nuclear physics and quantum mechanics, until something went wrong. The survivors now live in a brutal ecosystem divided among factions, and you begin alone and empty-handed in a world where the rules have changed.

Survive in the city

Keep your hunger and health in check as you explore. You can get food by farming, hunting or interacting with NPCs, and gather materials and salvageable components by scavenging or disassembling objects. More than 100 crafting blueprints cover the needs of your journey, from survival gear and furniture to mechanical, chemical and electrical systems.

You can buy properties and furnish them with appliances and workbenches to produce advanced items. Restore the electrical grid to power abandoned buildings and unlock new areas, while enduring lethal nuclear radiation. Blueprints also let you cook meals and manage a farm as you build and maintain a base.

Factions and relationships

NPCs follow dynamic routines: they work, eat and rest, and respond to changes in the world. Your interactions affect your relationships and can unlock new possibilities. Factions have their own organization, identities and long-term goals, which your decisions can alter.

Earn a faction's trust to gain access to restricted areas, crafting stations and supplies, or defy it and face the consequences. Your actions shape the future of the people around you, determining who thrives and who falls.

Strange creatures

Unexplained creatures roam the city's ruined buildings, a phenomenon no one has seen before. You can fight them, but discovering what they are and why they appeared is also a challenge.
