About 方舟不渡

February 14, 2156. YunChuan.

The elite have fled aboard the "Ark," leaving you — a "low-priority citizen" — trapped in a dead city swarming with the Assimilated.

This was never an accident.

Nano Tower Defense: Forge iron into soldiers

Equipped with the portable nano-engineering device provided by Old Ginger, your savior, you reforged the scrap iron, carbon dust, and silicon powder from the ruins into a deadly nanodefense tower.Every tower is a molecular fortress. Your only limits are power and processing time.

Your Choices Forge Your Soul

Every dialogue option matters. The Ethics-Order-Authenticity axis tracks your moral trajectory in real time. Will you become a Martyr, a Candle in the Dark, or an Abyss-Walker? Your soul-shape unlocks unique story branches and exclusive conversation paths.

The Ark Abandoned Humanity. You Won't.

The "outbreak" was just another test in the Ark Federation's "God Creation" project. The truth was left behind with the refuse. And you? You are the refuse. But refuse doesn't quit.
