Game Overview
A sealed-off nuclear settlement becomes a harsh social experiment where hunger, suspicion, and radiation shape every day. City 20 is a sandbox survival adventure set years after a catastrophic leak turns an isolated city into a forgotten quarantine zone. Rather than pushing you down a fixed storyline, it asks you to carve out a life among desperate residents, fragile communities, and dwindling supplies. The mood is bleak and tense, but its real appeal lies in seeing how a small decision can destabilize an entire neighborhood.
Survival revolves around scavenging abandoned locations, trading useful finds, and turning raw materials into tools that open up new options. You can hunt wildlife, lay traps, fish or forage, cultivate food, cook sustaining meals, and establish a more secure routine by claiming and furnishing an apartment. Violence remains an option when negotiations fail, though preparation and resource management matter because the city cannot endlessly replace what is lost. Work for residents, build goodwill with a faction, steal what you need, or provoke open hostility; every route affects access to shops, crafting spaces, shelter, and other practical advantages.
Its standout feature is the reactive population: residents follow personal needs, habits, relationships, and ambitions instead of functioning as static quest dispensers. Helping one person can undermine another, murder or theft can create lasting reprisals, and shifting faction pressure changes the way groups receive you over time. That gives the city a lived-in, unpredictable quality closer to a systemic simulation than a conventional survival campaign, with consequences that can be as useful or dangerous as any weapon. Fans of the emergent storytelling of STALKER, the social friction of Kenshi, or the resource anxiety of Project Zomboid should find plenty to experiment with, while patient newcomers can approach it as a slower-paced survival role-playing sandbox.

Setup Guide & Troubleshooting
How do I fix missing DLL errors for City 20 (v0.1.1)?
After extracting City 20 (v0.1.1), navigate to the _Redist or _CommonRedist folder inside the game directory and install DirectX, Vcredist, and any other dependencies included.
What should I do if the downloaded file is corrupted?
The full archive is 1.89 GB — make sure your download completed fully before extracting. Use 7-Zip to extract the files. If you still see a "file corrupted" error, re-download and try again.
Do I need to run the game as administrator?

How do I update my GPU drivers for this game?
The game won't launch — what should I try?
Check that extraction completed and your PC meets the system requirements, including Version 12. Note any error message before choosing a fix. If it identifies a missing runtime, install the required DirectX components or Microsoft Visual C++ Redistributable from Microsoft.
My antivirus is blocking the game — is it safe?
A warning needs to be investigated; the download source alone cannot confirm that a file is safe. Keep your security software enabled and review the detection details. Do not run or restore a flagged file unless you have verified that it is a false positive. If you are unsure, leave it quarantined.
