All Citadelle des Morts Easter Eggs and locations in Black Ops 6 Zombies

Almost every corner of the Citadelle des Morts map comes with some form of an Easter Egg. Typically, they’ll include a hidden treasure to uncover, while others bring up hidden secrets in Zombies’ ever-expanding lore.

If you’re up for the challenge, here’s a comprehensive guide to uncovering every single Easter Egg in BO6 Zombies Citadelle des Morts.

How to complete Citadelle des Morts Main Quest Easter Egg

Compared to the Liberty Falls and Terminus maps, Citadelle des Morts works a bit differently. Instead of performing steps in order, you must acquire items and complete objectives at your own pace. Here are the requirements you need to fulfill to complete the Citadelle des Morts Main Quest Easter Egg:

• Unlock the Pack-a-Punch Machine: Follow the guided steps from the first quest given to you.
• Speak to Krafft: The door to Krafft’s opens after unlocking PAP. Find him in the hidden room behind Quick Revive.
• Find and upgrade all elemental swords: Locate the Stamp and pick up the Dragon, Stag, Raven, and Lion Swords.
• Locate and use the Page Fragments: Pick up the four pages in the Sitting Room and place them in the book puzzle at the Undercroft. Use the hints from the symbols in the Tavern and utilize the book to activate the Point of Power Traps in the correct order.
• Find all Ritual Items: Locate Otto’s Horseshoe (turns into Pegasus’ Horseshoe), Ra’s Ank, Raven’s Tal, and Paladin’s Brooch.
• Acquire the four Incantations: Upgrade each Ritual Item to get the Dark Incantation (Raven Sword), Light Incantation (Lion Sword), Electric Incantation (Stag Sword), and Dragon Incantation (Dragon Sword).
• Get the Mystic Orb: Use all the items you’ve collected in the Knights room to collect the Mystic Orb. You can do this by inspecting each sword with each respective statue, then utilizing the suitable Incantation shortly after.
• Find the Guardian Key: Complete the sword trials to unlock the Guardian Key.
• Conquer the boss battle: Use the Guardian Key at the statue near spawn to trigger the final battle in Citadelle des Morts.

Most quests are available around Round 10, where you’ll discover various stamps from a zombie with a bucket/knight’s head. You can start on the Pack-a-Punch machine objective before then, guided by the game’s orange-colored mission. Just make sure to speak to Krafft near Quick Revive, or else you may miss out on specific quests.

While you’re out and about collecting each item, don’t forget to collect all the Perk Colas, PAP upgrades, and higher rarity weapons. You’ll need it to get through the final stage with the formidable boss battle. If you need more help with this Easter Egg, check out our complete BO6 Zombies Citadelle des Morts Main Quest overview.

All Citadelle des Morts Side Easter Eggs in BO6 Zombies

Although the Main Quest is your primary objective, additional Easter Eggs are waiting to be discovered, each offering unique buffs. Here’s a glimpse of what’s in store (we’ll delve into the more complex ones later).

Easter Egg	Where to Find	Easter Egg Previews
Free PhD Flopper (Bartending EE)	Locate three bottles around the map and complete the Bartender Minigame
Mister Peeks Free Perk	Shoot four Mister Peeks (bunny) around the map to gain a free perk for yourself and the entire team. Requires a Sniper Rifle with a decent zoom-in optic.
Rat King	Find 10 rats and earn a crown for the Rat King. Collect rare rewards, like high-rarity weapons and Essence, from each creature.
Free Perk, Ammo Mods, and more rewards	First, collect all four elemental swords, earn the four Incantations, and complete the Page Fragment book puzzle. Use each Incantation in front of the symbol puzzle in the Undercroft. This will begin a three-phase zombie battle, spawning many rewards by the end.
Free Raven Perk	Shoot the raven in the sewers when on the path to find the Ritual Items. After the raven exits the sewers, follow it for around three and a half minutes. Eventually, it will spawn a red orb with a free Perk inside.
Citadelle des Morts Music	Find three headphones to unlock an exclusive soundtrack
Caliburn Music	After you’ve upgraded the Fire Sword, return to the braziers you interacted with earlier and hit them with this weapon. It’ll cause them to re-ignite once more. Charge all three braziers to unlock the second music Easter Egg.
Secret Maya cutscene and Legendary GS45 Pistol	Equip Maya as an Operator and wait until Round 12. Look for a box sounding off Morse code in the Knights room. Open the door and defeat the boss inside for a key.
Chess Piece Protector	Like Terminus’ Mega Stuffy, you can unlock a companion to help you through Citadelle des Morts. Locate a chess piece in four potential spawn points. Then, place it on the chess board in the Sitting Room to farm kills.
New Fast Travel point	After interacting with the cannon, you’ll notice that the crank tools will be missing. To find it again, go to spawn and the Knights room to locate a gear piece and a blow torch. Repair it at the cannon to unlock a new fast travel point.
Bell Tower Monkey Bomb	This Easter Egg requires you to complete the New Fast Travel point one first. Once you’ve done that, you need to launch yourself from the cannon 100 times. A quest like this takes a lot of dedication and Essence, so bear that in mind before moving forward. By the 100th time, the cannon launches you over to the Bell Tower, spawning two Monkey Bombs. The Bell Tower will also run like a Monkey Bomb temporarily, luring in zombies with a few rings.
Wishing Well	Equip the Vulture Aid Perk and go to the well near Speed Cola. A Vermin will spawn out of it (if not, you may need to wait until another round). Throw a grenade down the well to gain some Essence. Then, interact with the well to throw in 10,000 Essence. Throw in another grenade and wait for the following round to earn double the Essence (make sure to pick the Double Points Power-Up).
Fire Balls	Ignite four fireplaces with a charged Fire Sword or a Molotov Cocktail. With all four lit up, fire balls will now spawn in and deal damage to zombies
Free Insta-Kill Power Up	Shoot the skull towards the right of the Tavern.
Free Nuke Power-Up	Shoot the nuke on the left side of Deadshot Daquiri near the Castle.
Free Max Ammo Power-Up	Shoot the ammo inside the window near Speed Cola
Free Max Armor Power-Up	Look above Entrance Hall in front of the stairs leading to the Dragon statue. Shoot the armor toward the ceiling.
Free Double Points Power-Up	Shoot through the doorway near the table with a stone tablet in Alchemical Lab.
Free Bonus Points Power-Up	Shoot the Bonus Points behind the couch in the Undercroft.
Free Full Power Power-Up	Shoot the Power-Up at the roof in the Knights/Dining Hall
Free Fire Sale Power-Up	Activate all the free Power-Up Easter Eggs and approach the well near Speed Cola
Pool Table	Shoot the pool table in the Tavern for free Essence

Mister Peeks Free Perk Easter Egg Citadelle des Morts locations

First, go to the opening near the Elemental Pop machine. Equip your Sniper Rifle and look through it to spot Mister Peeks. Shoot it, and you should hear a noise of laughter.

You can then head over to the Deadshot Daquiri area with the barn and look through another opening in the top-right corner. Mister Peeks will be dancing around on top of the mountain. If you can’t see it, you may need a better magnification for your weapon.

One of the last Mister Peeks can be found in the Knights room. Explore up top towards the castle to find him in the window.

Now, go to the Dungeon near Quick Revive to shoot the last Mister Peeks on a bench inside a cell.

All headphone locations for Citadelle des Morts Music Easter Egg

Interact with one of the first headphones on top of table at the Tavern.

Then, go towards the castle and take a right just before its entrance for another headphones.

Travel to the Undercroft and interact with a duffel bag on top of a couch. You’ll trigger the unique soundtrack for Citadelle des Morts, allowing you to jam it out to some tunes while killing zombies.

How to unlock Chess Piece Protector Easter Egg in Citadelle des Morts

A chess piece spawns in four potential locations. Take a right at the Dragon Statue near Jugger-Nog for the first one. Search for it on top of the table there.

It’ll likely be in its three other spots if it’s not there. Travel to the Tavern and look to the left of the red portal to look for a chess piece near the shelf with bottles.

Or, go to the building with Elemental Pop to locate one on the table next to the doorway.

The final spawn location takes you to the Dungeon (Quick Revive room). Search around the table inside.

Once you’ve found the piece, interact with a chessboard in the Sitting Room. Kill enough zombies within its radius to spawn a Chess Piece Protector companion.

How to unlock new Fast Travel point in Citadelle des Morts

Return to spawn and pick up the gear piece in the back. You’ll see the item inside a crate with fruit.

Next, head over to the Knights room and go underneath the Vulture Aid Perk machine. Grab the blow torch in the top-right corner of the room.

Place the two items in the cranker next to the cannon. In return, you can start cranking it again and move it to create another fast travel point.

All fireplace locations for Fire Balls Citadelle des Morts Easter Egg

After you’ve acquired Molotov Cocktails or upgraded your Fire Sword, ignite the fireplace in the Sitting Room near Stamin-Up.

Perform the same interaction on the hidden fireplace in Alchemical Lab.

Walk over to the next room (with the Knights) and ignite the fireplace underneath Vulture Aid.

Head over to the Tavern quickly by launching yourself from the cannon. You’ll find the last fireplace there, which will shoot out fireballs if done fast enough.

Although players have discovered a ton of Easter Eggs already, there may be a few more that have yet to be discovered. See what else you can find in Citadelle des Morts to get as much free gear as you can in BO6 Zombies.
