Doom Eternal: The Ultimate Weapons Guide

Doom Eternal has finally arrived and there’s an extensive list of weapons to keep the hordes of demons at bay.

As expected there are many familiar weapons like the chainsaw, shotgun, and minigun, but this time many of them have mods to increase their devastation. There are a total of eight weapons in the game and you’ll have to use all of them if you hope to survive. Many of the weapons have additional perks to make them even more effective.

So to help you become the ultimate demon slayer we have put together a guide to all the weapons in Doom Eternal, detailing their uses, various mods and how to use them most effectively. 

Pinky won't know what hit it.


Combat Shotgun

Doom Eternal Gun Guide Weapons Guide Combat shotgun modifications


This standard shotgun is your first gun in the game. It can do a great job of blasting enemies apart from close range with its high damage.

It also has the full auto and sticky bomb modifications available for it. The sticky bomb sticks to surfaces and is perfect for loosening up densely packed areas of enemies or even taking down larger demons. The full-auto increases your fire-rate which can be very handy when in a tight space or moving fast. 

There are also mode perks that can be used to increase the performance of the weapons. The combat shotgun has multiple perks available to work with the mods.

It can be used to clear out tight spaces or slow down faster demons. Because it’s hands-free it can easily be deployed if you are reloading, or if you are stringing together combos.

It has just one job of slicing through enemies and it does that job with ease. Unfortunately, it can be heavy on fuel, with larger demons requiring a full tank in order to cut them in half.

In Doom Eternal, the chainsaw is a must-use weapon because you can obtain ammo from the enemies you saw in half.


The Unmaykr

In order to get the keys, you have to complete six Slayer Gate challenges, that are tough encounters hidden throughout the game. It uses the same ammo as the BFG but has a widespread and more suited to taking down lone heavy enemies.

The frag grenade is always a useful tool for crowd control and buying you some time. It also works well in conjunction with other weapons or thrown around corners. It’s unlocked fairly early in the game on Hell on Earth (level one).


Ice Bomb

Ice Bomb Doom


The ice bomb is similar to the frag grenade, but instead of exploding, it freezes nearby enemies, giving you the opportunity to smash them.

The ice bomb is unlocked on the Fortress of Doom after Exultia.


Doom Blade
