Qwak! is a duck hunting light gun shooter arcade video game developed by Atari and released in 1974. In the game, ducks fly one at a time across the screen, and the player shoots at them using a light gun attached to the game cabinet. The player gets three shots per duck; ducks change direction away from missed shots and fall to the bottom of the screen when hit. A screen overlay adds images of reeds and a tree branch, and an image of a duck is added to a row at the top of the screen whenever a duck is hit. Games continue until a time limit, set by the machine operator, is reached. Qwak! is most likely the inspiration for the 1984 Nintendo Entertainment System light gun game Duck Hunt.
