Here's a unique gun papercraft from the World of Warcraft, the Mark "S" Boomstick.
This gun binds when picked up and improves hit rating and critical strike rating by 18%. Attack power is also increased by 34. You'll need Froststeel Tube, Hair Trigger, Saronite Bar, and a Walnut Stock to create this gun.
It pays homage to the 1992 horror-comedy movie, Army of Darkness (Bruce Campbell), by referencing the famous "boomstick" gun scene:
Ash: Alright you Primitive Screwheads, listen up! You see this? This... is my boomstick! The twelve-gauge double-barreled Remington. S-Mart's top of the line. You can find this in the sporting goods department. That's right, this sweet baby was made in Grand Rapids, Michigan. Retails for about a hundred and nine, ninety five. It's got a walnut stock, cobalt blue steel, and a hair trigger. That's right. Shop smart. Shop S-Mart. You got that?
