Duck Hunt was one of the two original pack-in titles for the first release of the game system. The game was not initially reviewed often, but given mediocre critical praise and positive gamer reaction. Prior to the NES version, Nintendo also made a Duck Hunt game based on Laser Clay Shooting System released in 1976.
The game has three modes: one and two-duck variations on the above formula, and a third mode called "clay pigeon shooting". The clay pigeons are much smaller sprites than the ducks, and, in later rounds, require faster reaction time to shoot down than in comparably numbered duck modes. In Vs. Duck Hunt, Clay Shooting mode appears as the second round with the first round being the two duck variation (the arcade version never had one duck). Also, in Vs. Duck Hunt, the dog appears in the clay shooting round when players miss the clay pigeons. In the NES version, the dog only appears in the duck shooting modes.
Throughout the game, the player is accompanied by a nameless dog that laughs at the player if no duck is hit, and congratulates the player if a duck is hit. Since then, the nameless dog has passed into video gaming folklore. According to urban legend, the dog can be shot, but this is not possible in the console version of the game. The feat of shooting the dog is possible in a bonus round of the game's arcade version, Vs. Duck Hunt. The dog can be shot only in the bonus round, and only after the final duck has flown from the screen or been hit. This is quite difficult, as the window of opportunity timewise is quite narrow. However, if the player succeeds, the shot turns the dog's face black with powder. The dog's carefree expression then immediately turns to one of rage. After briefly exiting the screen, the dog returns to the foreground, hobbling on crutches, and chides the player by saying, "Ouch, shoot the ducks, not me!" However, players will get no bonus points if they are able to hit the dog. Also, there have been several unofficial remakes in which the player is able to shoot the dog. The nameless dog makes a cameo appearance in the NES game Barker Bill's Trick Shooting (another Zapper game) and he can be shot.
While Duck Hunt does not have a traditional multiplayer mode, the manual states that a second player may plug in a standard NES controller in the other controller port and control the duck that appears. This option was only possible in the one duck mode, and could not be done with the clay pigeons.
Duck Hunt, and the characters in it, have made appearances in video games since its release in 1980s. The dog in Duck Hunt has appeared in Barker Bill's Trick Shooting and can be shot in the "Balloon Saloon" game. In Super Smash Bros. Melee, a trophy can be unlocked displaying the ducks from Duck Hunt. Similarly, in Super Smash Bros. Brawl, the ducks appear as a sticker, and the main theme is incorporated into the music track "Famicom Original Medley". Also, games in the WarioWare, Inc. series feature microgames based on Duck Hunt. Duck Hunt is also the Level 19 theme in Tetris DS.
One of the minigames in Wii Play for the Wii console is Shooting, a game similar in style to Duck Hunt, although with multiple targets, including ducks, targets, UFOs, and cans (a reference to Hogan's Alley), but lacking the dog, though one can be heard barking before the ducks fly out.
Duck Hunt is also a minigame on the arcade game Big Buck Hunter, including a different dog that only appears in jumping to the bushes. It does not laugh at the player should they fail to shoot any ducks.
