With a Wii Remote in one hand and Nunchuk in the other, you have a new level of control. For instance in The Legend of Zelda: Twilight Princess, the Wii Remote is your sword while the Nunchuk is your shield. In first-person shooters, the controller carries the burden of movement, freeing you to aim and fire using a more natural motion with the Wii Remote. In a football game, you can make your quarterback elusive with the Nunchuck controller while you look for an open receiver to throw to using the Wii Remote.
Please Note: Not official nintendo product, Nunchuk sold as seen in picture above (no packaging)
