Chaingun (Doom 2016)

The chaingun.

This article is about the weapon in Doom (2016). For other versions of this weapon, see:

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 Gatling gun, which returns as a weapon in the 2016 Doom game. It was first seen in Bethesda's E3 2015 demo footage, where it was briefly used to shoot at a pinky demon and what were later confirmed to be barons of Hell.

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

― SnapMap description

Tactical analysis

Far from simply conventional, the D12 uses Argent energy infusion to overdrive its firing mechanism, a piston capable of 220,000 PSI 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 tungsten slugs as ammunition.

Designed for sustained volleys, the chaingun deals high damage at a very high rate of fire. It requires a little spin up time before it gets up to speed, so watch out, as you are vulnerable. Spin it up behind cover before moving out into the open.

Modifications

Gatling Rotator

The weapon mod button can spin up the chaingun barrels without firing. Keep the weapon ready to go with this modification. If you release the button, though, it takes time to spin it back up. Fully upgrade this mod to penetrate through your targets and hit those behind them.

Upgrades

Upgrade	Description	Cost (weapon upgrade pts)
Improved Torque	Significantly increases the spin-up speed of the Gatling Rotator	3
Uranium Coating	Bullets penetrate through targets	6

Mastery challenge

Get 5 kills in 5 seconds while using the Gatling Rotator.

Reward: Incendiary Rounds
Bullets deal more damage when the chaingun reaches its maximum rate of fire.

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 more accurate and extremely powerful (stated to be rivaled only by the BFG-9000), it expends ammunition at an amazing rate, slows the user down significantly, and runs the risk of overheating the weapon if fired for too long, 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.

Upgrades

Upgrade	Description	Cost (weapon upgrade pts)
Rapid Deployment	Drastically decreases the transformation time for the Mobile Turret	3
Uranium Coating	Bullets penetrate through targets	6

Mastery challenge

Kill 4 or more demons during a single Mobile Turret deploy 5 times.

Reward: Ultimate Cooling
The Mobile Turret no longer stalls.

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.
  • Purchasing the Uranium Coating upgrade for the Gatling Rotator changes the chaingun's firing sound, while purchasing the same upgrade for the Mobile Turret does not.
• Despite the fact that this weapon fires 15 mm slugs, it still shares ammunition with the heavy assault rifle, which fires .50 BMG.
