The 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 cord. Its appearance when attached resembles the nunchaku, hence the name. 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 also provides a three-axis accelerometer for motion-sensing and tilting, but without a speaker, a rumble function, or a pointer function. One Nunchuk comes bundled with the Wii console. Additional Wii Remote units are sold separately without the Nunchuk. The two shoulder buttons, formerly named Z1 and Z2 respectively, had been reshaped and renamed since the Game Devel
