COD Black Ops 6 Zombies: How to Complete the Citadelle des Morts Story Quest

The release of Citadelle des Morts in Call of Duty: Black Ops 6 Zombies has been a hit, with players enjoying the chaotic and medieval atmosphere of the map and its unique features. However, many are still puzzled by the main quest, especially since Directed mode hasn't launched for the map yet.

So, for those looking to complete the main quest, here’s a comprehensive guide on how to finish the Citadelle des Morts main quest in Call of Duty: Black Ops 6.

How to Start the Citadelle Des Morts Story Quest

To begin the quest, follow the map's guidance through the castle, eliminating zombies to gather enough essence to open the doors. The first part is straightforward, as the map will lead you to the Pack-a-Punch machine using orange icons. Once you unlock the Pack-a-Punch, the prompts stop, and you'll be on your own.

The next step is to head to the nearby Quick Revive room, where you'll need to interact with a wooden door. This triggers a conversation with Gabriel Krafft and a cutscene, marking the official start of the main quest, which revolves around upgrading swords into elemental variants and performing magic incantations.

You’ll need all four elemental sword Wonder Weapons to complete the incantations (check out our full guide here on how to get all four Elemental Wonder Weapons). While you can tackle this quest solo, it’s easier to work with a team of four, as you can divide tasks and have each player focus on upgrading and swapping swords at the corresponding statues.

Step 1: Collect the Four Pages

The first objective is to collect four pages from a magic book, which are marked with glowing red runes. These pages can be found in and around the outside of the castle's Sitting Room, though their spawns are randomized in each game. Thankfully, they’re easy to spot with their glowing red symbols. Once you've collected all four pages, move on to the next step.

Step 2: Complete the Undercroft Puzzle

After collecting the pages, head to the Undercroft near Stamin-Up. You or a teammate will need the Melee Macchiato perk for this step, as you'll need to punch a cracked wall to reveal the puzzle. Next, head to the nearby tavern.

Here, you'll find six small glass bottles, each labeled with Roman numerals and symbols. Shoot the symbols in the order of the numbers, starting from 1 up to 6. You'll need to remember which symbols correspond to which number, so take a screenshot if needed.

Once you've solved the puzzle, an audio cue will signal the next step, and a red orb will appear. Interact with the orb to reveal a hidden spell book, where you'll place the pages you've collected.

After placing the pages, make a mental note of the order in which the symbols appear. The order you need to memorize is top left, bottom left, top right, and bottom right. This sequence will be important for the next step.

Step 3: Activate the Point of Power Traps

The next objective is to complete the Point of Power traps scattered around the map, which spawn after completing the magic book. Activate each trap by shooting the symbols in the order noted in the book and standing near the trap while killing zombies.

Be sure to follow the correct order, as doing it wrong will cause the quest to fail, and you may need to restart. Once you've done it correctly and the symbols stop glowing, Krafft will speak to you again, signaling you're ready to move on to the next step.

Step 4: Collect Ritual Items

Now, you’ll need to gather four ritual items tied to the elemental swords. These items can be collected in any order, and here's how to find each one:

• Pegasus Horseshoe: Shoot the horseshoe above the barn door near Deadshot Daiquiri. Use the cannon to shoot yourself out, creating an electric storm cloud. Find the cloud above the spawn area to collect the item.
• Ra’s Ankh: To collect this item, you need either a fire sword or three Molotov cocktails. Go to the cannon and use the fire sword or Molotovs at three different burn piles. After this, a Doppelghast will spawn. Defeat it to obtain Ra’s Ankh.
• Paladin’s Brooch: Shoot a crystal above the main entrance of the Dining Hall to create a beam. Continue shooting crystals in the room and nearby Alchemical Lab until the beam reaches the table in the Alchemical Room, revealing the Brooch.
• Raven Talon: Near the Pack-a-Punch room, use the Cave Slide to fast travel to the spawn area. Shoot the raven perched on the rocks, then shoot it out of the sky to collect the Raven Talon.

Step 5: Upgrade the Ritual Items

Next, upgrade each of the ritual items. This can be done in any order, but you must have all four elemental swords to proceed:

• Paladin’s Brooch: In the Dining Hall, interact with the yellow rune and kill zombies until a box spawns. Use the Solias Light sword to open the box and collect the Light Incantation.
• Ra’s Ankh: At the castle entrance, interact with the yellow rune and kill zombies until the box spawns. Use the Caliburn Fire sword to open the box and collect the Fire Incantation.
• Pegasus Horseshoe: At the spawn area, use the Durendal Lightning sword to open the box and collect the Storm Incantation.
• Raven Talon: In the Undercroft, use the Balmung Void sword to open the box and collect the Dark Incantation.

Step 6: Salute the Statues

Once you've collected all four incantations, visit the back wall of the Undercroft Stairway. A diagram will appear showing the order in which you must complete the incantations. This order changes each time, so make sure to note it down. Then, head to the Dining Hall, where four incantation boxes corresponding to each element will appear.

Use the incantations in the correct order on the statues. Each statue represents an element: Raven for Dark/Void, Lion for Light, Stag for Lightning/Storm, and Dragon for Fire. After completing the sequence, a glowing orb will appear, connecting the statues with light beams. Collect the orb to proceed.

Step 7: Charge the Orb

With the orb in hand, you need to charge it by completing steps at four map locations. You can complete these steps in any order:

• Lion/Light: Place the orb upstairs in the Dining Hall and survive while standing in the green orbs that spawn. Once they disappear, Krafft will speak, and you can move on.
• Dragon/Fire: Place the orb outside the castle entrance and kill zombies around it using the fire sword’s special attack, Molotovs, or the fire incantation.
• Lightning/Storm: Place the orb at the spawn area and kill zombies using the charged special attack of the Lightning sword or the Storm incantation.
• Raven/Dark: Place the orb in the Undercroft and kill zombies with the Dark incantation or the sword’s special elemental attack.

Step 8: Boss Fight Prep and Strategy

Now you’re ready to take on the final boss of this map, but you’ll need to summon it first. To do so, interact with the elemental animal symbols on the wall near the Sitting Room to insert the Mystic Orb and open a secret room. Head inside, activate the Ancient Mystic Recording on the table, and then pick up the Guardian Key from the cylinder that spawns.

Take the Guardian Key to the statue in the town square and deposit it at the statue's feet, which will trigger the boss fight. This fight is tough, so make sure you’re well-prepared. We recommend having powerful weapons and essential perks, especially if you're going solo.

Legendary weapons like the GS45 pistols with an Akimbo attachment or an LMG/assault rifle with tier-three upgrades will be invaluable. The fully Pack-a-Punched Drill melee weapon is also highly effective for dealing with the boss, and Deadshot Daiquiri augments make the boss’s armor much easier to deal with.

Be sure you have key perks like Juggernog, Quick Revive, and Speed Cola to improve your chances of survival. Lastly, Gobblegums like Perkaholic, Phoenix Up, and Max Ammo will help provide extra support during the fight.

In Stage 1, focus on avoiding the boss’s slam and fire attacks while targeting the weak points that appear on his body. In Stage 2, continue dealing damage to the new weak spots while managing the lava and fire hazards that will spread around the arena.

Finally, in Stage 3, concentrate your fire on the boss’s open chest to defeat him. Once you’ve successfully taken him down, you’ll have completed the Citadelle des Morts main story quest in Call of Duty: Black Ops 6 Zombies.
