Wild Gunman (ワイルドガンマン, Wairudo Ganman) is a light gun game created by Nintendo.
The original version was one of Nintendo's early electro-mechanical arcade games released in 1974. It consisted of a light gun connected to a 16mm projection screen. An image of a Wild West gunslinger was projected onto the screen and when his eyes flashed, the player needed to draw and shoot. If the player was fast enough the projection would change to that of the shot gunman falling down, otherwise it would show the gunman drawing and firing his gun. A piece of Chopin's "Funeral March" indicates the player's defeat.
