Koop City 20 PC

A city left to die

City 20 was a closed city, a place that didn't exist on any map. Behind its walls, scientists pushed the boundaries of nuclear physics and quantum mechanics. Then, something went wrong.
Sealed within their own nightmare and in a world now devoid of rules, the survivors gave rise to a new, brutal ecosystem divided into factions.
You find yourself in this ruthless reality alone and empty-handed. How far will you go to survive?

Survive, scavenge, craft

Keep your hunger and health in check, or neglect them and the City will claim you. Obtain food by farming, hunting, or interacting with NPCs. Scavenge for materials and salvageable components, and disassemble objects to recover parts to craft equipment.

Master the art of survival with an extensive system featuring over 100 crafting blueprints designed to support every phase of your journey, from essential survival gear and functional furniture to complex mechanical, chemical, and electrical systems.

Purchase properties and furnish them with appliances and workbenches to produce advanced items. Restore the electrical grid to bring power back to abandoned buildings and unlock new areas. Endure lethal nuclear radiation as you try to carve out your place in the city.

Whether you're cooking gourmet meals or managing a thriving farm, every blueprint helps you build and sustain your base against the harsh demands of the City.

A living world that doesn’t wait for you

All NPCs follow dynamic routines. They work, eat, rest, and react to a changing world.
Every interaction you have with them carries weight, influencing your relationships and unlocking new possibilities.
Learn about the factions, their organization, and their identity. Each pursues long-term goals that you can alter with your decisions.
Earn their trust to unlock restricted areas, crafting stations, and supplies, or defy them and face the consequences.
No path is already written. Your actions shape the future of those around you, deciding who thrives and who falls.

Something stirs in City 20

Not everything in City 20 can be explained by science. Strange creatures roam the city's ruined buildings - a phenomenon never seen before - and no one knows where they came from.
You can fight them, but understanding what they are and why they appeared might be the real challenge.
