Doom Eternal Walkthrough – Rip, Tear, and Survive the Chaos 2025

Hey there, Slayer!

So, you’ve decided to dive headfirst into the explosive, metal-fueled mayhem that is Doom Eternal? Good call. Whether you’re a returning fan of 2016’s Doom or brand new to the franchise, welcome to the ride. This walkthrough is your friendly companion through the game’s hellish gauntlet—no confusing lingo, just practical tips and a few laughs along the way.

Ready? Let’s rip and tear until it’s done. 🤘

What’s Doom Eternal All About?

Doom Eternal is the sequel to 2016’s Doom reboot, and it cranks everything up to 11. You’re the Doom Slayer, an unstoppable force of vengeance out to stop Hell’s invasion of Earth. The game mixes lightning-fast gunplay, intense platforming, and just the right amount of lore to keep things interesting.

Here’s the catch though: this isn’t your average run-and-gun shooter. You’ve gotta think fast, move faster, and manage your resources mid-fight. This walkthrough will guide you through each major level with strategies, secrets, and upgrades to keep you alive and kicking demon butt.

🌍 Mission 1: Hell on Earth

Welcome to the apocalypse.

The first level sets the tone. You’ll get your hands on the Combat Shotgun and quickly meet your first demons. This level eases you in—relatively speaking.

🔑 Tips:

Use Glory Kills (melee finishing moves) often to replenish health.
Chainsaw weak enemies to get ammo. Fuel regenerates over time, so don’t hoard it.
Take the high ground whenever possible. The verticality in this game is your friend.

Don’t miss the first Codex Entries and Extra Lives tucked behind breakable walls. Always explore before moving forward—you’ll thank yourself later.

🏛️ Mission 2: Exultia

Now things start getting spicy.

You’ll get the Dash ability here (double tap to zip around), and it changes everything. Dash into mid-air platforms and dodge enemy attacks like a ninja.

🔧 What to Look For:

Sentinel Batteries unlock upgrades and secrets in the Fortress of Doom (your cool space base).
Try out your new Flame Belch (left bumper). Burn enemies to get armor shards. Fire + loot = win-win.

Bonus: You’ll fight your first Hell Knight here—big, mean, and loves punching. Keep moving and don’t let him corner you.

🏗️ Mission 3: Cultist Base

The difficulty ramps up here.

You’ll get the Heavy Cannon, great for precision shots (and popping heads). It’s also the first level where platforming can feel a bit tricky, so get comfy with jumping and dashing.

🛠️ Key Tips:

Look for a Super Shotgun locked behind a gate—you’ll unlock it very soon, and it’s worth it.
Fight smarter, not harder. Use weak points: shoot off Arachnotron turrets or Cacodemon mouths with grenades.

And oh—start getting good at weapon switching. Doom Eternal is all about using the right tool at the right time.

❄️ Mission 4: Doom Hunter Base

Say hello to your first real boss: the Doom Hunter. This guy’s got a shield, a sled, and a bad attitude.

💥 Boss Tip:

Use Plasma Rifle to break shields.
Then swap to something heavy like the Rocket Launcher or Super Shotgun to deal real damage.

Before the boss, you’ll unlock the Super Shotgun (YES!). Its meat hook lets you grapple into enemies and blast them in the face. Pure satisfaction.

🌋 Mission 5: Super Gore Nest

This one’s a bloodbath—literally. Everything is red, gross, and filled with demons.

There’s a core you’ll need to destroy by activating keys across the map. Lots of backtracking here, so explore and take your time.

🎯 Must-Do:

Prioritize enemies: clear out fodder demons (zombies, imps) first for resources.
Use the Blood Punch (charged melee attack) on crowds. It’s amazing.

Don’t leave before grabbing the Rune upgrades here—especially ones that give you faster Glory Kills or a slow-mo while midair. Game-changers.

🚀 Mission 6: Arc Complex

You’re halfway there, Slayer!

This level feels like a war zone—buildings crumbling, demons everywhere, and even Marauders show up.

🧠 Marauder 101:

They block attacks, summon a wolf, and wreck you if you’re too aggressive.
Wait for their eyes to flash green—then shoot. Patience, young padawan.

The Chaingun makes an appearance too. Great for mowing down crowds and melting tough demons.

🧬 Mission 7: Mars Core

Time to BFG this thing.

You literally fire a cannon at Mars and blast a hole into it—how can you not love this level?

🎉 Highlights:

You’ll finally get the BFG-9000. Save it for big encounters—it clears rooms like a divine wrath.
Focus on secret hunting here. Tons of goodies like Mastery Tokens and Praetor Suit Points.

And did we mention you shoot yourself out of a cannon into Mars? Yeah, this game rules.

🦴 Mission 8: Sentinel Prime

Boss time again.

You’ll face the Gladiator, and he’s a tough cookie. Has a shield, multiple phases, and hits like a truck.

🪓 Boss Tip:

Wait for the green eye flash and counterattack.
Don’t get greedy—dodge and chip away.

Fun fact: this level has no extra secrets, so just focus on surviving the fight.

🧠 Mission 9: Taras Nabad

This level is beautiful and brutal.

Cathedrals, golden statues, and plenty of blood-soaked arenas.

You’ll find:

The Crucible, which lets you insta-kill enemies (limited charges, so save it).
A mix of ALL enemy types. It’s like a final exam.

Use everything you’ve learned here. Every mod, every dash, every upgrade—it’s all coming together.

🧊 Mission 10: Nekravol + Mission 11: Nekravol Part II

These two flow right into each other, so we’ll group ‘em up.

Expect tight corridors, vertical fights, and lots of heavy enemies.

😈 Quick Advice:

Equip Runes that give you more control in air or reduce stagger time.
Watch for Mastery tokens—these let you instantly finish weapon upgrades.

The final stretch is near!

🌀 Mission 12: Urdak

The game’s final push begins here.

This level is full of white, glowing alien temples and some pretty intense platforming. Think sci-fi meets heaven—until demons show up, of course.

✨ Focus:

Take your time with jumps—missing them means restarting big sections.
The Khan Maykr boss is tricky. Use the Ballista to break her shield.

You’re almost there, Slayer.

🔥 Mission 13: Final Sin

The final level. No secrets. No puzzles. Just an all-out brawl.

Face the Icon of Sin, a two-phase boss that’s larger than life. Literally.

⚔️ Final Battle Tips:

Target specific body parts to weaken him.
Use Crucible, BFG, and everything else you’ve got.
Keep moving. Standing still = death.

Once he falls, sit back and enjoy the ending. You’ve earned it.

🏆 Final Tips for New Slayers

Practice makes perfect. You will die, and that’s okay.
Rebind your controls if the defaults feel clunky. Making the Flame Belch or Chainsaw easier to access helps a ton.
Play the Master Levels and Battlemode for more action post-campaign.

🎮 You Did It, Slayer!

Congrats on making it through Doom Eternal! You’ve tackled one of the most aggressive, exhilarating shooters of this generation. And you’ve done it with style.

Whether you’re aiming for 100% completion or just enjoying the ride, remember: you are the Slayer. And Hell fears you.
