City 20. A secret nuclear city, quarantined after a radioactive leak and left to starve, a post-apocalyptic sandbox survival game where every choice shapes the world around you.

In this open-world survival experience, every decision is remembered. Factions guard their own agendas, people seek advantage, and the environment itself is a constant threat.

How far will you go to survive?

The world evolves whether you act or not. NPCs follow daily routines, adapt to a dynamic environment, and remember how you treat them.

You can help, trade, steal, or attack, but every action shapes your reputation with individuals and factions alike.

Work with or against organized factions in this living open world simulation.

Earn trust to access shops, resources, and safe areas, or betray them and be hunted down, exiled, and shut out of their territory.

Every NPC has a life of their own: they work, rest, eat, and adapt to the living city. A hungry guard might trade intel for food; an insulted citizen might refuse to speak to you for days.

Help them, exploit them, or ignore them, and watch the city react.

Find food, craft survival tools, restore power, and endure hazards. Grow crops to cook hearty recipes, hunt and trap wildlife, or scavenge rare materials to trade with NPCs.

With no scripted path, each playthrough is unique as factions rise and fall, NPCs live or die, and alliances shift in unexpected ways.
