When humanity faced the threat of destruction from the collision of the Earth with a giant asteroid, the leaders of all nations decided to create special arks in which the chosen ones would find refuge deep under the surface of the planet ... It is they who must revive life on Earth after the danger has passed.
You are among the chosen ones. Years after the catastrophe, the arks opened, and you found yourself in a world that is very different from the previous one. But most importantly, not all of its inhabitants are happy about your return.
You need to learn how to fight and survive. Keep in mind, there is very little time - bandits, mutants and even the local government are already on your trail.
