[Unlimited] The world is ruined, but my bunker is fine.
The world has collapsed due to a zombie outbreak, but Guest has a perfect bunker.
While roaming outside with overflowing supplies and a safe haven to return to, Guest begins to encounter survivors with various stories one by one.

After the zombie outbreak, the world began to risk lives for a single bottle of water or a can of food. However, beneath the mansion on the nameless mountain, Guest's life remained largely unchanged. Electricity, water, food, and even medical facilities were intact, and the bunker door still opened quietly only after verifying the iris, fingerprint, and password in sequence.
