Whoa! I did not anticipate stumbling upon a Gatling gun, but here we are, and it is glorious! This build is from a few years ago by Flickr user Julius von Brunk. The Gatling gun is a popular example of precursors to the modern machine gun. The hand-cranked, rapid fire, spring loaded weapon came about in the early 1860s when it was patented by its inventor, Richard Gatling. It gained notoriety during the Civil War, and has become a popular sight to see ever since! This particular build is modeled after the Chain Gun in Wolfenstein 3D. "It has the highest rate of fire in the game, which makes it the most powerful weapon. It is useful against large crowds and bosses. The Chain Gun can first be found in E1M2. The Chaingun is also the weapon used by most of bosses, and incidentally is the most useful against them, although they will never drop one when defeated." (Destiny Wiki) Thanks for this truly awesome build!
