The Nyko Kama is a third-party Nunchuk accessory created for the Wii video game console by Nyko, available in wireless or wired versions. In contrast to Nintendo's device, the controller takes its name from the traditional Japanese kama; a stealthy, curved weapon. Like the original Nunchuk, the Kama features an analog control stick, and "Z" and "C" buttons. With the use of 2 AAA batteries and an adapter dongle that plugs into the Wii Remote's expansion port, the wireless Kama is able to connect wirelessly. The wired version instead features a rumble motor, which allows it to offer force feedback when used with Nyko's Wand Wii Remote alternative.
