Unlock Your Slayer’s Full Potential: Master Weapons, Upgrades, Challenges, and More in DOOM Eternal
DOOM Eternal is a first-person shooter developed by id Software and published by Bethesda Softworks. It is the fifth main entry in the DOOM series and a direct sequel to 2016’s DOOM. The game is set in a chaotic world filled with demons and focuses on fast-paced action and intense combat. This guide will help you understand the various mechanics, weapons, and strategies that can help you level up and become a more formidable Slayer.
Basic Game Mechanics

To level up in DOOM Eternal, you must first familiarize yourself with the game’s mechanics. The game is built around the concept of “push forward combat,” which encourages players to engage enemies aggressively. This is supported by three core mechanics: Glory Kills, Chainsaw Kills, and Flame Belch.
- Glory Kills: When an enemy is staggered and flashing blue or orange, approach and press the Glory Kill button to execute a brutal finishing move. Glory Kills grant you health pickups, encouraging you to stay in the fight.
- Chainsaw Kills: The chainsaw is a powerful tool that can instantly kill most enemies, except for some larger demons. Chainsaw Kills reward you with ammunition, ensuring you always have the firepower to keep fighting.
- Flame Belch: The Flame Belch is a shoulder-mounted flamethrower that sets enemies on fire. While burning, enemies drop armor shards, providing you with extra protection.
Mastering these three mechanics is crucial to surviving in DOOM Eternal and leveling up effectively.
Weapons and Mods

DOOM Eternal boasts a diverse arsenal of weapons, each with unique mods that can be swapped in and out to suit your playstyle. Weapon Mods can be found in floating drones scattered throughout the levels or unlocked by spending Weapon Points earned from combat encounters and challenges.
Here are the weapons and their respective mods:
- Combat Shotgun: Sticky Bombs and Full Auto
- Heavy Cannon: Precision Bolt and Micro Missiles
- Plasma Rifle: Heat Blast and Microwave Beam
- Rocket Launcher: Lock-on Burst and Remote Detonation
- Super Shotgun: Meat Hook (default)
- Ballista: Arbalest and Destroyer Blade
- Chaingun: Mobile Turret and Energy Shield
- BFG 9000: No mods (default)
- Unmaykr: No mods (default)
As you progress through the game, upgrade your weapons and mods to maximize their potential. This will help you deal with increasingly powerful demons and contribute to your overall level progression.
Runes and Suit Upgrades

Runes and Praetor Suit upgrades further customize the Slayer’s abilities, enhancing your combat prowess and survivability.
- Runes: Runes are special enhancements that grant the Slayer unique abilities. You can equip up to three Runes at a time, and there are nine to choose from. Experiment with different Rune combinations to find the ones that best suit your playstyle.
- Praetor Suit Upgrades: The Praetor Suit can be upgraded using Praetor Suit Points found in levels or earned by completing challenges. These upgrades are divided into five categories: Environment, Frag Grenade, Ice Bomb, Fundamentals, and Exploration. Prioritize the upgrades that complement your playstyle and help you overcome specific challenges in the game.
Mastery Tokens

Mastery Tokens are a collectible resource in DOOM Eternal that allows you to bypass the mastery challenges for weapon mods and instantly unlock their full potential. These tokens can be found throughout the later levels of the game and are often located in secret or hidden areas.
In DOOM Eternal, each weapon mod has a mastery upgrade that provides a significant enhancement to the weapon’s functionality. To unlock a mastery upgrade, you need to complete specific challenges related to that weapon mod. These challenges often involve killing a certain number of enemies in a specific way or under certain conditions.
Mastery Tokens come in handy when you want to skip a mastery challenge that you find too difficult, tedious, or time-consuming. Instead of completing the challenge, you can use a Mastery Token to instantly unlock the mastery upgrade for your chosen weapon mod.
To use a Mastery Token, open your Arsenal tab, select the weapon mod you want to upgrade, and then choose the option to spend the token. Keep in mind that Mastery Tokens are limited in number, so use them wisely.
It’s important to note that there are 10 Mastery Tokens in the game, and here’s a list of the levels where you can find them:
- Taras Nabad: 1 Mastery Token
- Nekravol: 1 Mastery Token
- Nekravol – Part II: 2 Mastery Tokens
- Urdak: 3 Mastery Tokens
- Final Sin: 3 Mastery Tokens
By strategically using Mastery Tokens, you can further enhance your Slayer’s combat capabilities and optimize your favorite weapon mods to suit your playstyle.
Challenges and Milestones

Challenges and Milestones are objectives that reward you with experience points, weapon points, and other valuable resources. These objectives are divided into three categories: Mission Challenges, Weekly Challenges, and Series Challenges.
- Mission Challenges: Each mission in DOOM Eternal has three unique challenges that reward you with weapon points and experience points. Completing these challenges is essential to maximizing your level progression.
- Weekly Challenges: Every week, new challenges are introduced that reward you with experience points and cosmetics. These challenges can be completed in both the campaign and Battlemode.
- Series Challenges: Series Challenges are longer-term objectives that reward you with unique cosmetics and other valuable resources. Complete them to show off your skill and dedication to the game.
Extra Lives and Exploration

Extra Lives and exploration are crucial aspects of leveling up in DOOM Eternal. Extra Lives grant you an immediate respawn upon death, allowing you to stay in the fight and avoid restarting from checkpoints. These Extra Lives can be found in hidden locations throughout the levels.
Exploration is rewarded with valuable resources such as Codex Entries, Sentinel Batteries, Praetor Suit Points, Weapon Mods, and Runes. Additionally, discovering secrets and collectibles contributes to your level progression.
To maximize your exploration, invest in the Exploration Praetor Suit upgrades that reveal the Automap Station location, progression items, and other valuable resources on the map.
Battlemode

Battlemode is DOOM Eternal’s multiplayer component, which pits a fully-armed Slayer against two player-controlled demons. Playing and winning matches in Battlemode contributes to your overall level progression and unlocks unique cosmetics.
To succeed in Battlemode, familiarize yourself with the different playable demons and their abilities, as well as the various maps and their layout. Coordination and teamwork are crucial for the demon players, while the Slayer must use their full arsenal and mobility to outmaneuver and eliminate their opponents.
Slayer Gates and Secret Encounters

Slayer Gates and Secret Encounters are optional combat challenges that provide valuable rewards upon completion. They are scattered throughout the campaign and can be identified by their unique symbols.
- Slayer Gates: These are intense arena-style battles that pit you against waves of powerful demons. To access a Slayer Gate, you must find its corresponding Slayer Key in the level. Completing all six Slayer Gates rewards you with the Unmaykr, a powerful energy weapon. Additionally, each completed gate grants you three Weapon Points and an Empyrean Key.
- Secret Encounters: These are timed encounters that require you to defeat specific enemies within a set time limit. Successfully completing a Secret Encounter rewards you with Weapon Points, which can be used to upgrade your weapon mods.
Participating in these challenges not only contributes to your level progression but also tests your combat skills and mastery of the game’s mechanics.
Collectibles and Cosmetics

Collectibles and cosmetics are additional elements that, while not directly contributing to your level progression, add depth to the game and provide a sense of accomplishment.
- Collectibles: DOOM Eternal features numerous collectibles, such as Toy Collectibles, Albums, and Cheat Codes. Finding these items contributes to your Exploration progress and offers a fun side objective to complete.
- Cosmetics: As you level up and complete challenges, you’ll unlock various cosmetics, such as weapon skins, player icons, and nameplates. These items allow you to personalize your Slayer and show off your achievements in the game.
Master Levels

Master Levels are remixed versions of the campaign levels, featuring more challenging enemy encounters and layouts. These levels provide a high level of difficulty for experienced players looking to test their skills. Completing Master Levels earns you experience points and bragging rights among your fellow Slayers.
