You are one of the survivors who managed to survive the so-called "Nuclear Winter". A global nuclear war has occurred. Due to radiation, various mutants roam the streets. They pose a serious danger. Your city has turned into a lifeless wasteland with ruins, filled with mutants. The air is poisoned by radiation. The survivors have found refuge in the city's subway, which is a labyrinth of railways, tunnels and bunkers.

Inside the subway, there is a shortage of food, water and other supplies, which is why warring factions have formed: the Sparta Order (also known as the Rangers), the Red Line, the Fourth Reich and the Hansa. Other parts of the subway are contaminated with radiation and filled with dirty water or garbage. Some areas contain supernatural threats that can cause serious psychological trauma.

Your city is deserted, the air and water are radioactive, almost everything is covered in snow and ice. You are now in a bunker. You have been tasked with exploring the area and, if possible, finding food.

You have collected the necessary equipment: one machine gun, two pistols, and a gas mask. You have left the bunker.
