The controller is very innovative and has features that were not present in past video game controllers. The most notable feature of the Wii Remote is its motion sensing ability. Players are able to do multiple things with this remote, including swinging it, aiming, pulling back, using it as a steering wheel, and much more. It also has two separate controls, the main one or the one that is usually displayed, resembles a standard television remote control, and the second unit, title the Nunchuk expansion, allows the player to have more gameplay abilities. Some games require the Nunchuk expansion, which is possibly why it came free with the console. Much like the Wii remote, the Nunchuk also has motion-sensing controls. The Wii Remote also has a speaker located below the Home button and above the 1 button. This remote requires two Double AA batteries.
