The first
Light Zapper game for the
NES. Nothing could be simpler:
Ducks rose up out of a meadow and you shot them. Then this stupid dog came up and laughed at you if you missed. Alternatively, you could go
skeet shooting.
A fairly well-known feature of the game was that in the duck modes, the controller plugged into Port 2 could be used to "influence" the duck's flight path.
