The NES Zapper, also known as The Gun or Beam Gun in Japan, is an electronic light gun accessory for the Nintendo Entertainment System (NES) and the Japanese Famicom. It was released in Japan for the Famicom on February 18, 1984 and alongside the launch of the NES in North America in October 1985.
The Zapper allows players to aim at the television set display and "shoot" various objects that appear on the screen such as ducks, clay pigeons, targets, cowboys, criminals or other objectives. The Zapper is used on supported NES games, such as Duck Hunt and Wild Gunman. The Zapper could also be used on the title screens of games to move the cursor—done by pointing the device away from the screen and pulling the trigger—or starting the game (pointing at the screen and pulling the trigger).
