Qwak ! © 1974 Atari.
A light-pen duck-hunting game that would be an early predecessor to Nintendo's Duck Hunt
The gun used an electronic duck call that would sound off before the ducks would go flying into the air and sound when a duck was hit and fell to the ground.
The reeds/grass were painted onto the glass in front of the 23" B&W monitor.
Released in November 1974, selling at an MSRP of $795.
This was the first time that a video arcade machine would use light-gun technology.
