Duck Hunt has three different game modes to choose from. In “Game A” and “Game B”, the targets are flying ducks in a woodland area, and in “Game C” the targets are clay pigeons that are fired away from the player’s perspective into the distance. In “Game A”, one duck will appear on the screen at a time while in “Game B” two ducks will appear at a time.[6] “Game A” allows a second player to control the movement of the flying ducks by using a normal NES controller.[7] The gameplay starts at Round 1 and may continue up to Round 99. If the player completes Round 99, he or she will advance to Round 0, which is a kill screen (in “Game A”) where the game behaves erratically, such as targets that move haphazardly or don’t appear at all, and eventually ends.[8]
