Game Description:Get ready for action so insane you'll wish your Wii came with a seatbelt! Grab your Wiimote and hold on tight. Take the wheel of some supercharged Monster Trucks and muscle your way around mud-soaked arenas, climb gravel slopes, and conquer unforgiving terrain in punishing weather conditions. You're in for some serious bone-jarring, white-knuckle, four-wheelin' excitement. Smash into other drivers to send them careening off-course. Get your technique down and unlock more courses, vehicle upgrades, and even more monstrous trucks. Go head-to-head with friends or get down and dirty in single-player modes including Time Trial, International Arena Challenge, and more.
