This is a working game of Duck Hunt in vanilla Minecraft. It includes a difficulty selector, a start and kill switch, and signs labeling different parts of the redstone and their functions. Slightly sloppy redstone, but very reliable and functional nonetheless. If desired, downloading some kind of gun mod is recommended. Hope you enjoy!
