Step 1: Unlocking Pack-a-Punch Machine

Begin your Citadelle des Morts journey by unlocking the Pack-a-Punch machine. Follow the on-screen prompts, which will lead you deep into the castle’s lower levels. You’ll encounter locked gates that need to be shot open. Be prepared for a mini-boss encounter. Upon defeating it, it will drop a crystal. Take this crystal and place it at the location where the mini-boss emerged. This action will activate the Pack-a-Punch machine, allowing you to upgrade your weapons. Then, proceed to the area near the Quick Revive perk, where you’ll find a barred cell door. Interact with it to speak with Craft, thus officially initiating the main Easter egg quest and prepping you for the challenges ahead.

Step 2: Collect Ritual Items and Elemental Sword Upgrades

Progressing through Citadelle des Morts requires gathering ritual items and upgrading elemental swords. While ritual item collection can begin immediately, sword upgrades become accessible after Round 10, when special stamps become available. These stamps are key to unlocking the swords needed for the next steps in the Easter egg quest. Efficiently managing both tasks is crucial for successfully advancing through the map’s challenges.

Unlocking the Swords

Reaching Round 10 triggers the appearance of special zombies wearing buckets on their heads. Eliminating these zombies yields stamps, which are essential for unlocking the elemental swords. You can only carry one stamp at a time. It’s recommended to immediately take each stamp to the knights’ room and assign it to a new knight, activating all the swords for upgrading. Prepare the swords as soon as possible because it is better for the next part. By doing this, you ensure the swords are ready for the upgrade process, streamlining your progress through the subsequent stages of the quest.

Sword Upgrades

With all swords unlocked, attention shifts to upgrading them. Each sword requires a unique challenge related to its element. Remember what the element of the sword is. Upgrading the Lion Sword (Light) involves meleeing glowing parasites. The Stag Sword (Electric) requires collecting lightning rod parts. The Raven Sword (Void) involves solving a symbol-matching puzzle. The Fire Sword requires interacting with a cauldron and surviving near the dragon. Successfully completing each challenge enhances the sword’s power, making you more formidable.

Step 3: Obtain Ritual Items

The next phase involves gathering four ritual items, each linked to a specific soul box. The order of acquisition doesn’t matter, allowing flexibility in your strategy. The electrified Horseshoe requires you to use the cannon and follow an electric storm. The Ank needs you to burn three piles of wood around the map. The Paladin’s Bust requires you to redirect a beam of light in the knight’s chamber. The Raven’s Talon needs you to shoot a raven while sliding down a cave. After acquiring each item, place it on its corresponding soul box to activate a zombie-slaying ritual.

Step 4: Wall Puzzle and Book Pages

The wall puzzle is a multi-stage challenge. Start by melee attacking the wall using only a standard melee. The swords don’t work, so don’t even try it. It should reveal symbols on the wall. Proceed to the bar to find six jugs, each displaying a Roman numeral. Interact with each jug to reveal a symbol, noting them down in numerical order. Return to the wall and shoot the symbols in the order of your noted numbers. Solving the puzzle opens a hidden area containing a book missing pages. Locate four scattered pages in the nearby couch area and insert them into the book. After this, you’ll have to charge traps in the area by killing zombies around it.

Step 5: Knight Challenges

The Knight’s Challenges demand precise execution. The Knights dictate the order in which the elemental swords must be used. Retrieve the swords and take them to the ritual box it corresponds to. First, melee the box with the correct sword. Follow this by using the incantation item from your tactical slot. Finally, inspect the sword in front of the corresponding knight statue. Confirmation of success comes with the knight’s salute. Repeat this sequence for each sword, paying close attention to the required order. Successfully completing all the challenges will summon the Mystic Orb.

Step 6: Mystic Orb Challenges

The Mystic Orb challenges are linked to the elemental sword upgrades. These are the last steps to complete the Black Ops 6 Easter Egg. Use the Lion Sword in the Dining Hall, killing zombies and absorbing light. Then, use the Fire Sword and kill zombies in the Courtyard to collect souls. Following that, use the Electric Sword in the Town Square, charging the orb with special ability kills. Finally, use the Void Sword in the Undercroft. After completing each challenge, take the Mystic Orb and place it on the marked wall section, opening a hidden chamber and revealing the Guardian Key.

Final Step: The Guardian Boss Fight

Enter the boss arena fully prepared, equipping yourself with perks, upgraded weapons, and protective armor. Stock up on items to enhance survivability. The boss fight unfolds in three phases, each escalating in difficulty. The initial phase requires breaking the armor on the boss’s shoulders and legs to expose weak points. After each phase, the boss retreats, summoning waves of zombies. Clear these waves before continuing. The arena gradually shrinks, introducing lava hazards that demand constant movement and heightened awareness. Successfully navigating these challenges and defeating the boss allows you to collect the artifact and complete the Easter egg.
