Doom Eternal weapons: how to master all the gun types

All weapon mod challenges

Featured post Doom Eternal weapon mod

Early on in Doom Eternal, you’ll pick up your first weapon mod. These are secondary fire effects and there are a maximum of two per weapon. You can swap on the fly if you’ve unlocked both of them and they can make a standard shotgun either throw sticky bombs or turn into a fully automatic shotgun. But there is a way to make them even better.

Doom Eternal weapons guide

From the second mission onwards, you’ll begin to earn weapon points. They are obtained through standard combat encounters, but can also be earned via boss fights, secret encounters, and special hard arenas called “Slayer Room challenges”. This Doom Eternal weapons guide will give you all the information you need from which weapon mod perks are available, to how to get weapon mod mastery skills.

Weapon mod perks

Weapon points can be spent on upgrading your weapon mods to add a few more effects. Almost all weapons have two weapon mods available to it, though the Super Shotgun only has the Meat Hook. There is one other gun in the game, but it doesn’t have any weapon mods available for it (Not that it needs it).

If I have any recommendations for which perks to unlock as soon as possible, both of the Heat Blast perks for the Plasma Rifle are solid upgrades. When you get the Super Shotgun, try to nab both of the available perks for it as it gives you another way to burn enemies without having to wait for the recharge time on the flamethrower.

The following table has all of the weapon mod perks available, their effects, and their costs. I highly recommend using the search function for this table, using the weapon mod name as the search term.

Doom Eternal weapon mod

Mastery skills and tasks

Once you have spent enough weapon points to earn all of a mod’s available perks, you’ll have a chance to unlock that mod’s “Mastery” skill. These are incredibly powerful effects that can, just as an example, turn a gun from a rather average machine gun into a mini-rocket launcher.

The catch is that there is a challenge you must complete before you unlock that mastery skill. Luckily, the Fortress Of Doom hub area has a basement prison where the Doomguy likes to keep some demons prisoner. Progress also carries over even if you die in combat or reload the checkpoint, so if you want to be really cheeky, you can blow up an Arachnotron’s turret before reloading to do it over and over.

You’re shown it after the second mission and you can come down to slay some demons as much as you wish. Here are all of the mastery skills and the challenges you need to complete to unlock them all:

Shotgun

  • Sticky Bomb: Launch five sticky bombs before having to reload.
    • Task: Destroy 25 Arachnotron turrets with sticky bombs.
  • Full Auto: Killing a demon with the Full Auto mod will drop shell ammo.
    • Task: Kill 15 Pinkies with Full Auto mode.

Heavy Cannon

  • Precision Bolt: A headshot kill will set off a powerful, secondary blast that deals damage to nearby demons.
    • Task: Get 75 Precision Bolt headshot kills.
  • Micro Missiles: Fire micro missiles indefinitely without having to reload (still consumes ammo).
    • Task: Hit three enemies with a single salvo of missiles, 15 times.

Plasma Rifle

  • Heat Blast: After triggering a fully charged Heat Blast, plasma projectiles will have a damage boost for a short time.
    • Task: Kill two demons with a single Heat Blast, 30 times.
  • Microwave Beam: Demons that are detonated by the Microwave Beam will trigger a concussive blast that falters nearby enemies.
    • Task: Kill at least one demon with the Microwave explosion, 15 times.

Rocket Launcher

  • Remote Detonate: If a rocket is detonated while the Proximity Flare is active, additional explosives will activate to create a larger area of effect.
    • Task: Kill 60 enemies while the Proximity Flare is active.
  • Lock-On Burst: A second lock-on target can now be acquired before firing rocket bursts.
    • Task: Kill 15 Prowler Demons with the Lock-on Burst.

Super Shotgun

  • Meat hook: Meat hook now sets enemies on fire, causing armor drops if blasted with the Super Shotgun.
    • Task: Kill 50 enemies with the super shotgun while grappled onto them.

Ballista

  • Arbalest: Arbalest will start recharging instantly after a direct hit.
    • Task: Kill 20 Cacodemons with the Arbalest.
  • Destroyer Blade: Fire Destroyer Blades before they have reached maximum width.
    • Task: Kill at least three enemies with the Destroyer Blade, 15 times.

Chaingun

  • Mobile Turret: Mobile turret no longer stalls.
    • Task: Kill 5 enemies with a single turret without overheating, ten times.
  • Energy Shield: Dealing enough damage with the Chaingun while the Energy Shield is active will launch it forward on release. Any demons hit by this projectile will falter.
    • Task: Deal 20,000 damage while Energy Shield is active.
