The game unfolds in a dystopian New York where environmental crisis has forced the population to literally inch closer to the sky through a massive network of bridges to avoid the toxicity of the surface. The violent change in society created a feverish need for laborers to assist the wealthy elites on the upper levels. A solution presented itself in the cloning of a new working class with the right qualifications — Neanderthals. Strong enough for labor yet ultimately subservient, the Neanderthal population grew and eventually clogged the lower levels of the city where they were forced to fight in blood sports for the amusement of the wealthy.

Powered by the all-new Crytek 2 engine, M.O.B. depicts a brutal struggle between the past and future. As an elite Neanderthal fighter, Matteo, players will fight their way through a sprawling vertical world filled with frenetic shoot-outs and distinctly gruesome mayhem. With the help of a prototype biomechanical arm, players will literally tear through the environment and charge fallen debris for use as hand grenades, as well as dismember and demolish anything that stands in their way.
