Killer robots are attacking major cities across the United States, and the military is powerless to stop them. Players control one of Project H.A.M.M.E.R.'s cyborg prototypes: half-man, half-machine, with an extraordinary weapon - and the power to save the world. Equipped with a hammer of amazing strength, players represent the only hope against an unstoppable army of marauding automatons. Players use the Nunchuk controller in one hand to maneuver through a variety of vast and detailed environments and the Wii Remote in the other just like a real hammer to control the hero's weapon. Lift it into the air and bring it down to smash robots to smithereens, or the "A" button for quick hammer flurries.Enter a world of non-stop action and relentless destruction. Players will reduce robots to scrap metal as they battle their way across the US. If they see an enemy, they smash it, and continue until the country is saved.
