Chaingun/Doom (2016)

The Chaingun is a minigun that returns in Doom 4. Its 6 rotating barrels give it a very high rate of fire. Very useful when fighting numerous and strong enemies. It shares its ammo pool with the Heavy Assault Rifle.

There's a modification where it can make the chaingun break open into a three-barreled rotary gun. While active, the chaingun has no wind up time and damage is tripled but it can cause the gun to overheat and will eventually jam.
