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.
Grab the Wii Remote and start swinging. 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 manoeuvre through a variety of vast and detailed environments. They use the Wii Remote in the other just like a real hammer to control the hero's weapon. Swing the controller side to side to make the in-game hammer send enemies flying. Lift it into the air and bring it down to smash robots to smithereens. Use the A button for quick hammer flurries.
