In 2013, the world collapsed apocalypse, almost completely destroyed humanity and turned the surface of the Earth into a poisonous wasteland. A handful of survivors took refuge in the depths of the Moscow metro, and humanity plunged into the new Middle Ages. The year 2033 has come. A whole generation has grown underground. Besieged city-stations are struggling with each other for survival, and terrible mutants are wandering outside of cities. Your name is Artem. You were born in the last days before the earth burned down, but grew underground. Before you did not go beyond the city limits, but the fateful event forced you to go on a desperate journey to the very center of the underground labyrinth to warn the survivors of the monstrous threat looming over them. From the abandoned dungeons under the subway, your path will lead to the surface, into the wild deserted land, where your actions will decide the destiny of mankind. But what if the real threat is internal?
