Chaingun (Doom 2016)

The Delta-12 chaingun, also simply known as the chaingun and referred to in short as the D12, is a fast-firing multi-barreled automatic weapon, similar to a, which returns as a weapon in the Doom game. It was first seen in Bethesda's demo footage, where it was briefly used to shoot at a pinky demon and what were later confirmed to be barons of Hell.

Far from simply conventional, the D12 uses Argent energy infusion to overdrive its firing mechanism, a piston capable of 220,000 pressure, resulting in an extremely high muzzle velocity of 5000 feet per second. This crucible is self-recharging, using the barrel heat produced from firing to keep its internal battery charged. It utilizes 15 mm caliber slugs as ammunition.

"A large drum-fed rotary machine gun with a high rate of fire."

Design
The D12 is the largest version of the chaingun so far, stated to weigh 45 kilograms and stretching most of the way across the view. It appears as if though it would be more in-place as a component of an aircraft or armored vehicle than as a portable weapon. With modifications applied, this incarnation can have three independent sets of triple-barreled turrets which can be fired simultaneously.

Modifications

 * Gatling Rotator
 * This unapproved third-party modification to the chaingun overrides the release mechanism of the firing crucible. This allows firing of the weapon to begin before the barrels reach full rotation velocity. This trades faster initial fire for a longer spin-up time.


 * Mobile Turret
 * This modification adds another crucible and compression piston chamber, doubling the weapon's firing rate by using all three of the barrel clusters simultaneously. While extremely powerful and stated to be rivaled only by the BFG, it expends ammunition at an amazing rate and also overheats the weapon, requiring a long cool-down period to be endured after its use. The barrels' metal can be seen to glow red after a firing cycle is complete.

Gatling Rotator

 * Improved Torque
 * Decreases spin-up time.
 * Cost: 3 weapon points


 * Uranium Coating
 * Shots penetrate enemies.
 * Cost: 6 weapon points


 * Mastery - Incendiary Rounds
 * Unlocked by killing five enemies with the Gatling Rotator mod within five seconds. Bullets will do more damage once maximum firing rate is reached.

Mobile Turret

 * Rapid Deployment
 * Decreases spin-up time.
 * Cost: 3 weapon points


 * Uranium Coating
 * Shots penetrate enemies.
 * Cost: 6 weapon points


 * Mastery - Ultimate Cooling
 * Unlocked by killing four enemies in a single deployment five times. The weapon can no longer overheat.

Trivia
Once the Uranium Coating upgrade has been obtained for either modification, the Chaingun's muzzle flash will turn blue as a possible nod to Doom 64.
