As a result of these characteristics, it's implied that the chaingun can be held single-handedly like a pistol by a muscular user (as illustrated by the Heavy Weapon Dude, or by its appearance in the Doom comic) or perhaps held like an assault rifle.

Unlike most real-world gatling-style weapons such as miniguns, the Doom chaingun has a pistol-grip styled handle and trigger group similar to those found on assault rifles or submachine guns, rather than being an infantry-portable minigun seen in the films Predator (1987) and Terminator 2: Judgement Day (1991).

An actual chain gun only has a single barrel and uses an electric motor to drive a chain connected to the bolt assembly, moving it back and forth to load, fire, extract, and eject ammo cartridges.

If the Doom chaingun is associated with real weaponry, it is a Gatling-style weapon with rotating barrels similar to a minigun.

However, it was a blue color, and had a significantly higher rate of fire, functioning as the ultimate weapon in-game the submachine gun was more in-line statwise to the Chaingun.

Wolfenstein 3D, the game id Software released immediately before Doom, included a similar chaingun.

Its graphic was slightly different, in that the tips of the barrels did not extend past the barrel band.

The chaingun first appeared in the Doom press release beta.

Doom's instruction manual refers to this motion as 'the chaingun cha-cha.'

The target of chaingun fire often appears to turn and shuffle rapidly in place, due to the continual interruption of its sprite sequences.

As with the rocket launcher and BFG9000, the first-person chaingun sprite is slightly too large for the screen, and can only be viewed with a level or resource editor.
