"Duck Hunt" is a shooter game in which the goal is to shoot moving objects on the television screen while they are in mid-flight. The game is played in first person and involves the use of a NES Zapper light gun, which the user targets and discharges at the screen. In "Duck Hunt", one must try to hit as many ducks as possible within the time limit otherwise known as a "shot". When a bird reaches the screen, it will go through the cycle of flying away from the viewer, turning around mid-air, then coming back toward the camera before finally falling down onto another part of the map. Each time a bird flies away from the camera, it is considered a new target. Therefore, even though there may be birds on the screen that you have already shot, you can still fire at them again for bonus points. There are two modes in "Duck Hunt": Free-for-all and Score Attack. In free-for-all mode, the player has no time limit and can stay on the screen as long as they want taking shots at ducks. However, if they do not shoot enough ducks in a row, the score will drop below 100 points and the game will end. In score attack mode, the player is given five seconds to shoot as many ducks as they can without missing them. If they fail to do so, the score will drop below 100 points and the game will end.
