To find the four torn page fragments, go into the Sitting Room of the castle (you’ll know it because it’s where the Stamin-Up machine is). To save time on this puzzle, be sure to carefully retrieve the page fragments based on where they are placed in the room from the left side to the right. The spawn points for these glowing pages change every match and can be tricky to find as they are surprisingly well hidden.

After collecting all four pages, ensure you have the Melee Macchiato perk, which you must use when going down into the Undercroft. Hit the wall at the end of the room, which looks obviously breakable and differently shaded, revealing a new puzzle and wall of symbols.

Solve the Undercroft Code Wall Puzzle

This puzzle can be tricky simply because it requires memorizing six different symbols. After revealing the hidden wall with the various symbols, you must return to the spawn area and proceed to the Tavern, where you can find six bottles with the Roman numerals I through VI on them. Each bottle has a different symbol, and the goal is to memorize which bottle has which symbol and shoot the corresponding symbols on the wall in numerical order. Be careful, though, as every time you shoot the correct symbol, the wall changes the order in which it has these symbols.

The bottles in the tavern are as follows:

• I: On the Bar in the Tavern on the left-hand side
• II: On the table in the Tavern next to the Barricade on the Northeast side
• III: On the booth in the Tavern that is above the cellar staircase
• IV: On the Tavern’s second floor, next to the pool table
• V: Located across from the armor upgrade in the Tavern, placed on a booth
• VI: On a small round table next to one of the entrances in the Tavern

Instead of constantly going back up and down from the Tavern to the Undercroft, players should take screenshots of each bottle to know which symbols to shoot in order. After shooting all six symbols on the wall in the correct order, a red orb will appear and reveal a hidden slot next to the wall puzzle containing a book. Place the four torn page fragments into the book to begin the next puzzle.

Find the Book Symbols and Traps

After placing the four torn pages onto the hidden book, four glowing red symbols will appear, each correlating to four different points of traps that will now be activated on the Citadelle Des Morts map. The four symbols in the book differ in every game, so we can’t definitively tell you where to go.

To complete this part of the puzzle, you need to activate the traps that correspond with the symbols in the book in the correct order. You must do the trap for the top left page first, then the bottom left symbol, then the top right symbol, and lastly, the bottom right. When locating these power trap symbols on the map, you’ll know you’re at the correct one when it is outlined in white.

Interact with the symbol on the floor and stay in the circle, allowing you to fire special bullets from your weapons. After killing a certain amount of zombies while standing on the symbol, you’ll get dialogue from Krafft indicating you completed it. The symbols will disappear from the book as you complete each power trap.

Find the Four Animal Ritual Items

Once the Symbol Power Traps are all completed, you’ll want to locate four different Animal Ritual Items, as well as upgrade them. Here are the locations of the four animal ritual items, as well as how to upgrade them:

• Ottos Horseshoe: hanging above the door of the Barn located at the Nature Path. Shoot at the horseshoe to enable you to pick it up off the ground. After retrieving it, go to the hillside Ramparts across the castle’s entrance, aim the Lion cannon towards the spawn area, and then shoot yourself out of it. This will create a trail of lightning that will follow you as you land in spawn and a storm cloud above the map. Follow the storm cloud, which will spawn zombies you must kill, eventually upgrading the item to the Pegasus’ Horseshoe.
• Ra’s Ank: To begin, craft three Molotovs, which you have to throw at three different locations on the map— one at a bonfire at the top of a castle in the Rampart area, one above the entrance to the castle, which you can see when facing towards where the Lion cannon is facing, and one bonfire that is above the speed cola. After lighting the final bonfire, a Doppelghast will spawn. Killing it will cause it to drop the Ra’s Ank item.
• Paladin’s Brooch: Go to the Dining Hall where all the armor suits are located, which have upgradable swords. Above the Vulture Aid Perk in the area is a red crystal players must shoot. This will create a beam of light pointing to another red crystal, and you must shoot each one that the light points to until you create a beam of light that leads to the Alchemical lab. When the light hits a statue/bust, it generates the Brooch, which you can pick up.
• Ravens Talon: In the Pack-a-Punch room, take the secret slide entrance back to the spawn area. During the animation sequence of using the slide, shoot a raven that you see on the right side near the exit of the area. This will cause the Raven to fly out into the open area of the map. Quickly shoot it; it will drop the final ritual item you need, the Raven’s Talon.

After collecting the four ritual items as well as upgrading whichever ones are necessary, four golden circles will appear around the map. They work similarly to the Book Symbols traps mentioned earlier, and you must take each item and place it in the appropriate section, which will trigger waves of zombies you have to kill to complete the upgrades for each item. The Golden Circle locations are as follows;

• Pegasus’ Horseshoe– Town Center
• Raven’s Talon– Castle Undercroft
• Ra’s Ankh– Castle Courtyard
• Paladin’s Brooch– Castle Dining Room

Solve the Animal Symbol Puzzle

Once all the above steps are done correctly, go to the Undercroft stairs, where the wall will now show four animal symbols (each represents one of the four upgraded swords) and a Roman numeral next to each one. As with several other steps here, the Roman numerical sequence for each animal symbol is randomized in each game. Be sure to memorize which animal goes first according to the numbers and the color associated with the animal symbol.

Depending on the order, you’ll want to find the box associated with the upgraded sword on the map. Unlock the box with the sword, pick up the incantation related to it, and return to the Dining Hall, where you’ll use the incantation on the armor as well as place the sword on the suit of armor, which will cause it to raise its arm as well as making it glow gold (if done correctly). Here are the locations of each incantation box:

• Caliburn Sword – At the Entrance Hall of the Castle
• Durendal Sword – Town Square, Northwest, next to a boarded-up gate
• Balmung Sword – Undercroft, to the left of the entrance
• Solais Sword – Dining Hall, to the right of the doorway facing South

Once the incantations and swords are placed on each suit of armor (in the correct order depending on the animal symbol that spawned for you in the Undercroft), a Mystic Orb will spawn in the center of the Dining Hall.

Charge the Mystic Orb

Now that you have the mystic orb, you must take the orb to four different locations around the Citadelle Des Morts map and complete elemental challenges to charge the Orb. For once, it doesn’t matter what order you do these challenges. There will be small circular metal components sticking out of the wall where you will need to place the Orb to start the challenge, located in the following areas:

• Caliburn(Dragon)– [Located in Castle Courtyard] Get elemental fire kills near the orb using the sword, the Napalm Burst ammo mod, or other fire-related items like Molotovs.
• DurendalSword (Stag)– [Located in Town Center] Get Electrical elemental kills in the town center using the sword or the dead wire ammo mod.
• Balmung(Raven)– [Located in Undercroft] Get Void elemental kills using the Dark Incantation or the Shadow Rift ammo mod.
• Solais(Lion)– [Located in the Dining Room on the second floor] stays in the green orbs around the room and gets kills.

Defeat the Guardian in the Citadelle des Morts Final Encounter in Black Ops 6 Zombies

After what will undoubtedly be twenty-plus rounds of zombies, all of these extensive and tedious steps will finally be completed with the mystic orbs’ charging. Before triggering the final encounter, ensure you have all the perks unlocked, as well as whatever Pack-a-Punched weapons you need for the final boss. Once you’re good and ready, take the charged orb and place it in the wall where the Undercroft stairs are located, at the center of the four animal symbols. This will then give you the Guardian Key, which you must take to the statue in the town center. This will then trigger the final boss fight.

From here, it’s entirely up to you to vanquish the Guardian in Citadelle des Morts, which will then complete the exhaustive main quest line of the zombie map in Black Ops 6 Zombies.

Completing the quest line will reward you with the Jackknife Operator Skin for Weaver, 5,000 XP, and a calling card.
