Chaingun (Doom Eternal)



The Chaingun makes its return as a weapon in Doom Eternal, having been updated with a sleeker appearance similar to the pistol. Similar to the previous game, it shares its ammunition with the heavy cannon. The mobile turret mod from its previous incarnation returns as well, appearing to function the same as it did last time. In addition, due to the loss of the spin-up time from 2016, the second mod is now a shield as demonstrated in the QuakeCon 2019 Doomhunter clip.

Lore
The M220 Chaingun is an 80-pound, six-barreled autocannon that fires 7.62x51mm AE rounds. It was originally conceived as a standard issue weapon for ARC mech-soldiers, whose exo-armor would be able to support a payload beyond that which normal infantry would be able to use. The custom-designed AE cartridge is built for the exclusive use of the M220's rail system, increasing the projectile velocity while avoiding overheating.
