To get out of the labyrinth in which he finds himself, the hero will have to create equipment and weapons, upgrade his skills and solve puzzles. In the game you can build safe shelters, as well as make forays and fight with mutant animals to get a new dose of serum. Moreover, each new injection can not only improve the hero’s abilities, but also cause mutations in him.
