A gun that fies by having its bolt operated by a chain. Despite years of misuse (started by id game's Doom) it is always a single barrel gun.

A Chaingun Cha-Cha is when you shoot someone repeatedly with a sub-machine gun or machine jun while the person is standing up.
The Cha-Cha bit is where the person judders with the force of each bullet, but doesn't fall down.
