The NES Duck Hunt is a staple of the system. It and Super Mario Bros. was bundled with a ton of the systems, mostly to show off the Zapper.

There's not much to it, either, dog jumps into field, flushes out ducks, and you have to shoot them down.

But! According to manual (which you probably won't have access to at this point in the game's life), a second player can join in the fun.

Just plug in a controller along with the Zapper, and a second player can control the directions that the Ducks fly.

And unlike some other games, this actually works.
