The Quad Launcher is a fanon tank in Diep.io that shoots 4 RPG bursts. Made by aDeformedPickle. Do not steal. It upgrades off of the RPG and the Predator. (No, it is not based off of Fortnite. I thought of this idea way before Fortnite came out).

The Quad Launcher shoots 4 missiles, each in turn before reloading with the reload cannon on the front that looks like half a triangle. As I explain in the article Classes, this tank is a Reload/RPG poly-class. It shoots like the Reloader, but slower and 4 shots instead of 3. To blow them up, press Shift or Right-Click.
