CITADELLE DES MORTS.
By Caleb Irvin / September 16, 2026 / No Comments
⚔️ FOUR ELEMENTAL SWORDS.
Because apparently one Wonder Weapon is for peasants. 😂
The quest works solo or co-op. Solo players can return upgraded swords to their knight statues and swap between them as needed.
1. 💥 Open the Castle
Start in Town Square and work uphill toward the castle.
Eventually you’ll reach the cannon on the ramparts.
Rotate it toward the castle entrance and fire.
💥 BOOM.
Castle’s open.
Continue inside toward the Oubliette Room.
2. 🔫 Unlock Pack-a-Punch
Inside the Oubliette is a locked container.
Shoot the three locks.
A Doppelghast emerges.
Defeat it and collect the:
💎 BLOOD AETHERIUM CRYSTAL
Put the crystal into the portal mechanism.
The machine transforms into:
🔫 PACK-A-PUNCH.
Activision’s official guide confirms the Oubliette is the Pack-a-Punch location.
3. 👴 Talk to Gabriel Krafft
Go into the room containing Quick Revive.
Find the wooden door.
Interact with it.
👴 GABRIEL KRAFFT
speaks with you.
This is important because it properly activates the Main Quest progression after Pack-a-Punch.
4. 🪙 Collect FOUR Stamps
Starting around Round 10, helmeted zombies begin appearing.
Kill them and they’ll drop:
🪙 STAMPS.
Each Stamp can be given to one of the four knight statues in the Dining Hall.
Each knight gives you a:
⚔️ BASTARD SWORD.
We need all four eventually.
The knights are:
🐉 Dragon
🦌 Stag
🦁 Lion
🐦⬛ Raven
And each sword has its own elemental upgrade.
5. 🔥 DRAGON → CALIBURN
Take the Dragon Knight’s Bastard Sword.
Place it into the dragon statue at the top of the Entrance Hall stairs.
Now three fiery braziers become important.
Collect the fire from one.
🔥🏃 RUN.
Carrying the fire drains your health, but killing zombies while running can restore some health.
Return the flame to the dragon statue.
Repeat for all:
🔥 Flame #1
🔥 Flame #2
🔥 Flame #3
The sword becomes:
🔥 CALIBURN.
Activision identifies the three Aether-fire brazier locations as the Ramparts, Nature Path entrance, and Town Square.
6. ⚡ STAG → DURENDAL
Take the Stag Sword.
Now collect:
⚡ THREE LIGHTNING RODS.
Once you have all three, take them to the mechanism on the Hillside Ramparts.
Insert them.
A lightning storm begins.
Stay near the device and use the Stag Sword during the sequence until it’s electrically charged.
Hit the mechanism with the charged sword.
Repeat until the ritual completes.
You receive:
⚡ DURENDAL.
7. ☀️ LION → SOLAIS
Grab the Lion Sword.
Kill glowing Parasites to charge the sword.
Take the charged sword to the special door in the Upper Village.
Hit the door.
A glowing symbol appears.
Repeat:
Parasite → charge sword → hit door
until you’ve completed the required charges.
Enter the room.
Place the sword into the pedestal.
Now glowing symbols appear.
Shoot the symbols in the order shown on the pedestal.
Complete the puzzle and—
☀️ SOLAIS.
8. 🌑 RAVEN → BALMUNG
Grab the Raven Sword.
Go into the Alchemical Lab and locate the Antiquity associated with your match.
There are several possible Antiquities, and the one you receive determines the correct zodiac/element combination for the next puzzle.
Take the Antiquity and Raven Sword to the circular puzzle beneath the Tavern.
Set:
♈ Correct Zodiac
🔺 Correct Element
When you’ve entered the proper combination, the portal sequence begins.
Guide the purple energy into the portals until all three stages are complete.
Then—
🌑 BALMUNG.
And now:
⚔️ ELEMENTAL SWORD ROLL CALL
🔥 Caliburn
⚡ Durendal
☀️ Solais
🌑 Balmung
9. ✨ Get the FOUR ritual items
Now we need four items corresponding to the four elements:
☀️ Paladin’s Brooch
🔥 Ra’s Ankh
⚡ Pegasus’ Horseshoe
🌑 Raven’s Talon
Each one has its own acquisition puzzle.
Once you’ve obtained a ritual item, a glowing ritual circle becomes available somewhere around Citadelle.
10. ☀️ Light Incantation
Take the Paladin’s Brooch to its yellow ritual circle in the Dining Hall.
Activate it.
Kill zombies around the circle.
Eventually a golden chest appears.
Hit it using:
☀️ SOLAIS.
It opens and gives you:
✨ LIGHT INCANTATION.
11. 🔥 Fire Incantation
Take Ra’s Ankh to the ritual circle outside the castle entrance.
Kill zombies inside the ritual area.
A chest appears.
Hit it using:
🔥 CALIBURN.
Collect:
🔥 FIRE INCANTATION.
12. ⚡ Storm Incantation
Take Pegasus’ Horseshoe to its ritual circle in the Town Square/spawn area.
Complete the zombie ritual.
Open the chest using:
⚡ DURENDAL.
Collect:
⚡ STORM INCANTATION.
13. 🌑 Dark Incantation
Take the Raven’s Talon into the Undercroft.
Activate its ritual.
Kill zombies.
When the chest appears, hit it using:
🌑 BALMUNG.
Collect:
🌑 DARK INCANTATION.
Now we have:
⚔️ Four elemental swords
and
✨ Four Incantations.
Because apparently being a Zombies player now requires a degree in medieval wizardry. 😂
14. 📄 Collect FOUR Torn Pages
Go into the Sitting Rooms.
Search for:
📄 Torn Page #1
📄 Torn Page #2
📄 Torn Page #3
📄 Torn Page #4
You’ll need these for the book puzzle.
15. 👊 Reveal the symbol wall
Get:
🥊 MELEE MACCHIATO.
Go into the Undercroft.
Find the cracked wall and punch it.
Behind it is the symbol puzzle.
You’ll need the symbols associated with the numbered flasks in the Tavern.
Record them in numerical order and activate the matching symbols on the wall.
A hidden compartment opens.
Place your:
📄 FOUR TORN PAGES
into the book.
16. 👁️ Complete the FOUR Point-of-Power traps
Your pages correspond to four Point of Power trap symbols around Citadelle.
Read the pages in their proper positions and find the matching traps.
Activate the appropriate trap.
Then get zombie eliminations inside the trap until it shuts itself down.
Repeat for:
👁️ Trap #1
👁️ Trap #2
👁️ Trap #3
👁️ Trap #4
When all four are finished, you’ve unlocked the next clue.
17. 🔢 WRITE DOWN THE KNIGHT ORDER
Go to the Undercroft Stairway.
A diagram appears showing the four elemental animals with Roman numerals.
For example, yours might be:
I — 🦌 Stag
II — 🐉 Dragon
III — 🐦⬛ Raven
IV — 🦁 Lion
⚠️ YOUR ORDER IS RANDOM.
Write it down.
This determines how we interact with the knights.
18. 🫡 MAKE THE KNIGHTS SALUTE
Return to the Dining Hall.
Start with whichever knight your diagram labeled:
I.
Grab that knight’s:
matching elemental sword
and
matching Incantation.
Stand in front of the statue.
Use the Incantation.
The knight begins glowing.
Now:
⚔️ INSPECT YOUR SWORD.
The knight salutes.
🫡
Yes.
After everything we’ve done in Zombies…
WE HAVE TO IMPRESS FOUR STATUES WITH PROPER KNIGHT ETIQUETTE.
😂
Repeat in your randomized:
I → II → III → IV
order.
19. 🔮 Get the MYSTIC ORB
Once all four knights have saluted, beams connect the statues.
Something descends into the center of the room:
🔮 MYSTIC ORB.
Pick it up.
We need to charge it with all four elements.
20. ☀️ LIGHT ORB CHALLENGE
Place the Orb into its holder upstairs in the Dining Hall.
This challenge is different from the other three.
Green energy orbs appear.
🟢 RUN THROUGH THEM.
Collect them until they disappear.
Once complete:
☀️ LIGHT CHARGED.
21. 🔥 FIRE ORB CHALLENGE
Take the Orb outside the castle entrance.
Place it into its holder.
Now get kills near it using:
🔥 FIRE DAMAGE.
You can use Caliburn’s elemental attack or the Fire Incantation.
Finish enough kills.
🔥 FIRE CHARGED.
22. ⚡ STORM ORB CHALLENGE
Take the Orb into Town Square.
Place it.
Use:
⚡ DURENDAL
or
⚡ STORM INCANTATIONS
to get the required elemental kills.
Complete the challenge.
⚡ STORM CHARGED.
23. 🌑 DARK ORB CHALLENGE
Take the Orb into the Undercroft.
Place it into the holder.
Use:
🌑 BALMUNG
or
🌑 DARK INCANTATIONS
to kill zombies around it.
Finish the challenge.
🌑 DARK CHARGED.
You can complete these four Orb challenges in any order.
24. 🔮 Place the fully charged Orb
Return to the Undercroft Stairway, where you found the knight-order diagram.
There’s a slot in the center.
Insert:
🔮 THE CHARGED MYSTIC ORB.
You’ll hear more dialogue.
Then collect:
🔑 GUARDIAN KEY.
And now…
You know exactly what time it is.
⚠️ POINT OF NO RETURN
Before using the Guardian Key:
Repair your armor.
Finish your weapon upgrades.
Get your perks.
Restock equipment.
When you’re ready, return to:
🏘️ TOWN SQUARE.
Look at that gigantic stone statue.
Insert the:
🔑 GUARDIAN KEY.
And…
🗿
“Uh…guys?”
“Was that thing always moving?”
😂
25. 🗿 THE GUARDIAN — PHASE ONE
You’re transported into the boss arena.
Meet:
🗿 THE GUARDIAN.
This fight has three major stages and isn’t timed, so staying alive matters more than rushing damage.
Initially, you’ll be stripping away his armor.
Keep moving around the arena and avoid his:
🔨 Hammer attacks
🔥 Fire/slam attacks
Damage his armor until glowing weak points appear.
Then:
🎯 SHOOT THE WEAK POINTS.
26. 🔥 PHASE TWO
Eventually the Guardian becomes more dangerous.
Sections of the arena begin filling with:
🔥 LAVA.
So now we have:
🗿 Giant stone knight
🔨 Giant hammer
🧟 Zombies
🔥 Floor becoming lava
Because apparently the Guardian went to the same boss-design school as every other Zombies monster. 😂
Keep damaging him until new weak points appear.
27. 💥 PHASE THREE
Eventually:
❤️ HIS CHEST OPENS.
That’s your major final weak point.
Keep moving.
Avoid the hammer.
Avoid the lava.
Control the zombies.
And unload into:
🎯 THE EXPOSED CHEST.
Keep firing until—
