In the game, players assume control of the last ranger, Walker, who must survive in a world inhabited by dangerous mutants after it was hit by an asteroid. The majority of mankind died, with only a dreary wasteland left behind. While new settlements and factions emerged, in all this misery, a group called the Authority declared themselves as the new military power. On a hunt for the precious nano technology in order to consolidate their dictatorship, Walker, therefore, makes an ideal target. The game will take place 30 years after the original game, and feature a cast of both new and existing characters.
