Nintendo Wii Nunchuk

The Nintendo Wii Nunchuk is the first controller attachment Nintendo revealed for the Wii Remote at the 2005 Tokyo Game Show. It connects to the Wii Remote via a long cord, and its appearance while attached resembles the nunchaku. It features an analog stick similar to the one found on the Nintendo GameCube controller and two trigger buttons. It works in tandem with the main controller in many games. Like the Wii Remote, the Nunchuk controller also provides accelerometer for three axis motion-sensing and tiltling, but no speaker or rumble.

A Nunchuk controller comes bundled with the Wii console. Separate Nunchuk controllers will retail in Japan for JP¥1,800, in the United States for US$19.99, in Canada for CA$24.99, in Europe for €19, and in the United Kingdom for £14

The two shoulder buttons, formerly named Z1 and Z2 respectively, had been reshaped and renamed since the Game Developers Conference. The circular top shoulder button, now called C, is much smaller than the lower rectangular shoulder button, now called Z. The C button was oval shaped, while the Z button was square.

The body of the Nunchuk controller measures 113 mm long, 38.2 mm wide, and 37.5 mm thick. The cord for the Nunchuk is approximately three and a half to four feet long.

Product images and an Overstock.com listing indicate that game accessory manufacturer Intec is releasing a third-party Nunchuk controller for the Wii Remote. This is the first third-party expansion to be discovered for the Wii Remote.
