Chaingun – Mobile Turret The Chaingun already deals high damage at a very fast rate, but the Mobile Turret mod amplifies everything that’s great about the weapon. While you have to sacrifice a little mobility to use the Mobile Turret mod, the Chaingun’s damage output and rate of fire are significantly increased. Doom Hunter Sleds just wash away under mobile turret fire. Same thing with Hell Knights and those lava sword arm having dude’s (Tyrant’s?).
- DOOM Eternal Do you guys prefer the energy shield of the mobile turret mod for the chain gun and why I only use the chain gun on the dread night, baron of hell and tyrant and im trying to see if the energy shield is better.
- The Chaingunner Zombie (AKA Zombie Chaingunner or Chaingun Commando) is the most powerful zombie enemy in Hunter's Moon. The Chaingunner Zombie differs a lot in appearance from the other zombies. For one, he is barechested, wearing only a helmet and trousers. Moreover, he is more muscular, having been augmented by the demonic forces for their own use - deploying the Chaingun Commando.
In DOOM Eternal, you will find various different weapon mods that unlock some secondary fire effects. You can use up to two of these per weapon and swap them out whenever you want.
After the second mission, you start getting weapon points from fighting enemies and defeating bosses, finding secret encounters, and completing Slayer Room Challenges.
Our DOOM Eternal Weapon Mods guide will tell you everything you need to know about weapon mods.

Doom Eternal features a wide array of powerful weapons, but the chaingun is without a doubt one of the best weapons in the game. It’s a straight upgrade over Doom 2016’s chaingun in every way, firing faster and dealing more damage, which is perfect for Doom Eternal’s more challenging encounters. The chaingun is acquired early in Doom Eternal’s campaign, but you can miss it if you don’t grab it before the mission ends. Thankfully, it’s hidden in plain sight, and the only way to miss the chaingun is to deliberately ignore it as you play through the level. This is how to get the chaingun in Doom Eternal.

How to Get the Chaingun in Doom Eternal
The chaingun is obtained in Doom Eternal’s fifth mission, Super Gore Nest. This mission sends you to a massive gore nest that is one of the leading factors playing into the demonic invasion of earth. Super Gore Nest is a fairly lengthy mission, and the chaingun is hidden right in the middle of it. Play through the mission normally until you reach a giant outdoor area with three colored pedestals. You should already have the Yellow Key by this point, so clear the area of demons and insert the Key into the corresponding yellow slot. You’ll still need a red and blue key to proceed with the mission, so enter the newly opened doorway to continue your mission.
As you fight your way through the newly opened passage, you’ll come across a small room with a few demons inside. In this room, you should see the chaingun behind a glass window, sealed away by a locked door. This door will be unlocked later on, so just keep moving for now. Make your way through the toxic sludge, learning about the Rad Suit along the way. Eventually, following the main mission path will lead you to the Red Key. The passage behind the Red Key will open once you pick it up. Continue onward and you should reach the room with the chaingun shortly. The door will then unlock, allowing you to obtain the chaingun.
