This press release has details on the game; here's a portion:

M.O.B. tells of 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 call for a new breed of laborer and modern science answered the call. Society then witnessed the birth of new working class -- Neanderthals. Physically powerful but mostly obedient, the Neanderthal population exploded and clogged the lower levels of the city where they were forced to fight in blood sports.

As Matteo, a Neanderthal fighter specially engineered for mental and physical superiority, players will blast their way through a sprawling dystopia where the glow of towering megastructures illuminate epic firefights and brutal hand-to-hand combat. Using a biomechanical arm made specifically for Matteo by a mysterious scientist, players will rip through hordes of ancient enemies, such as Neanderthal thugs, as well as futuristic foes, such as Hover Droids and security drones.
