An unknown catastrophe has ended civilisation as we know it. You live in a small society of survivors on a hill outside the big city where the air is just barely breathable. In the city, it's worse, but riches left from before the catastrophe still lures people into the deadly mist. Including your brother. And now he's gone missing. With your gas mask and a few days of supplies, you enter the city. Will you find your brother? What else hides in the mist?
