When you're out biking, don't you wish you could go faster? Well, you'll feel like you are with Nitrobike. In the game, Nitro-charged rockets are strapped to your dirt bike, so you'll speed past your opponents to the finish line. But don't use too much, or you'll slide right into the mud. Wii Remote rumble, blur effects, and screen shake will make this the fastest experience you'll encounter on the Wii. Play against your friends in the six-person online multiplayer game. If you like bowling, you can play the Rack 'em Up feature, where you smash your bike into a frame of king-sized pins in the four-player game. You can also upgrade your bike and unlock lots of characters in the game.

You Gotta Be You - Career mode, upgradeable bikes, and lots of unlockable characters will ensure you stand out as the most Xtreme of the Xtreme

Six-Person Online Multiplayer: A first on the Wii. Challenge up to five of your friends and cover them with mud as you burn past them to the finish line.
