An abnormal fog has engulfed the city.

Visibility is reduced to just a few meters, and the outside world has fallen silent.

Your base is a safe underground shelter.
However, to survive, you must venture outside.

Within the fog, you will find:

• Abandoned houses

• Ruined supermarkets

• Streets that only retain traces of former lives

And beyond the fog —
something is out there.

First-Person Survival FPS

• Combat is only one means of survival, not the goal

• Choosing when to run, hide, or wait is critical

Exploration & Resource Management

• Gather food, tools, and materials to stay alive

• Careless decisions can lead to instant death

Underground Base

• A completely safe location

• The only place for crafting, storage, and preparation

Intense Tension Created by Dense Fog

• Constant anxiety caused by limited visibility

• Sound, shadows, and distance amplify fear

About the Changing World

In this city, the layout of buildings and the resources you can obtain mysteriously change every day.

A house you found yesterday may not exist today.
Even if you head to the same location, an entirely different scene may unfold before you.

One thing is certain —
past experience will not carry over to the next day.

Every expedition is always unknown,
and it is your moment-to-moment decisions—not memory—that determine life or death.

■ Intended Experience

This game does not aim to deliver flashy action or endless combat.

• The fear of taking a single step into the fog

• The decision of “Should I go back now, or keep going?”

• The relief of safely returning underground

It offers a survival experience that tests the player’s judgment and psychology.
