Master the complete step-by-step guide to conquer Black Ops 6 Zombies Citadelle des Morts main story Easter egg
Getting Started: Essential Setup
Embark on your Citadelle des Morts Easter egg journey by following this comprehensive progression guide through every stage of Black Ops 6 Zombies’ challenging main quest.
Citadelle des Morts presents one of the most intricate Easter eggs in Black Ops 6 Zombies, featuring multiple complex stages that require precise execution and strategic planning to conquer successfully.
Veteran players familiar with Liberty Falls and Terminus Easter eggs will appreciate the increased complexity of this medieval castle setting, which debuted on December 5 with Season 1 Reloaded and offers a fresh undead-slaying experience.
The ancient Avalon castle environment introduces unique medieval-themed mechanics that differentiate it from previous maps, providing both challenge and novelty for experienced zombie hunters.
Our team extensively tested this Easter egg through multiple playthroughs, documenting each phase with detailed observations and strategic insights to streamline your completion process.
Begin by completing the initial tutorial sequence to activate the Pack-a-Punch machine, which grants access to the specialized laboratory situated strategically between Stamin-Up and the knight’s courtyard area.
Proceed to the Dungeon zone where Quick Revive is located, then locate the wooden door in this area. Interacting with this door triggers Krafft’s appearance, initiating the crucial conversation that officially starts your main quest progression.
Krafft’s distinctive appearance makes him immediately recognizable – his unique eyewear stands out dramatically in the medieval castle environment, ensuring you won’t miss this key NPC interaction.
Weapon Progression: From Bastard Swords to Wonder Weapons
Around round 10, you’ll encounter distinctive bucket-headed zombies charging toward you – these special enemies are crucial for progressing through the sword acquisition phase.

Eliminate bucket head zombies to collect the stamp items they drop consistently. Transport these stamps to the four knight statues positioned in the dining hall, where you can redeem them arcade-style to acquire the complete set of four Bastard Swords.
Sword acquisition marks only the beginning of your weapon evolution journey. The subsequent critical phase involves transforming these standard blades into powerful Wonder Weapons through specific upgrade procedures.
Each sword upgrade follows distinct methodologies that can prove time-intensive. For comprehensive upgrade assistance, consult our specialized guide covering all Wonder Weapon sword acquisition methods in Black Ops 6 Zombies.
Pro Tip: Farm bucket head zombies efficiently by training them in open areas and using explosive weapons to maximize stamp collection rates. Prioritize keeping one zombie alive at round end to control the pacing.
Avoid This Mistake: Don’t waste stamps on partial sword sets – wait until you have enough for all four Bastard Swords simultaneously to streamline your progression and conserve resources.
Puzzle Challenges: Symbols and Incantations
After securing your Wonder Weapon swords, return to the initial spawn area tavern. Here you’ll discover six bottles marked with Roman numerals I through VI, each displaying unique symbols that must be memorized for the upcoming puzzle sequence.
Navigate to the undercroft area beyond Stamin-Up and utilize Melee Macchiato to break through a specific wall section. This action triggers rapidly appearing blue symbols that must be shot in sequential order from one to six to complete this Easter egg segment.
Your next objective involves collecting four distinct incantations, obtainable in any sequence. These magical phrases are essential for advancing through subsequent ritual phases of the Easter egg.
Acquiring all incantations from scratch requires substantial effort, but our dedicated Citadelle des Morts incantations guide provides comprehensive assistance for this collection phase.
Strategy Insight: Use your phone camera or screenshot function to capture the Roman numeral bottle sequences, as the symbol recall requirement is time-sensitive and precision-critical.
Common Pitfall: Players often fail the symbol shooting sequence by not pre-aiming at spawn locations. Practice the symbol pattern recognition before activating the wall break to improve success rates dramatically.
Advanced Rituals: Book Pages and Knight Salutes
With incantations secured, progress to the pages puzzle phase. This requires collecting missing book pages before attempting the main puzzle solution.
Return to the flooded basement area used for the symbols challenge. Adjacent to where you previously shot symbols, locate a book missing several pages. The page retrieval process is straightforward and manageable.
Following page collection, you’ll encounter the primary book puzzle awaiting solution.
The book puzzle activates only with one or more incantations in your possession. Execute the sequence starting left side (top to bottom) then right side (top to bottom). Subsequently, inspect all Point of Power traps throughout the map for symbol matches, activate each trap and eliminate zombies within until premature termination, confirming symbol completion.
Verify successful completion by returning to the book – red symbols should transition to black coloration. Repeat this methodology until all four symbols are processed, then advance to the next stage.
Beyond Stamin-Up, descend one staircase level to discover a wall mural. Memorize the elemental appearance sequence, then apply your incantation while inspecting appropriate swords for each courtyard knight until illumination occurs before you.
Efficiency Tip: Coordinate with teammates to simultaneously check multiple Power traps, significantly reducing the time investment required for the book puzzle completion phase.
Warning: Incorrect sword-knight pairings will not trigger the glow effect. If no illumination occurs after 10 seconds, try a different sword combination immediately.
Final Confrontation: Orb Charging and Boss Battle
Knight illumination confirmation signals successful sword application, triggering Mystic Orb appearance as your reward and unlocking the subsequent Easter egg phase.
Orb charging follows specific sequential requirements across four familiar locations from your incantation tasks.
Each orb placement requires interaction to initiate color transformation, spawning zombie waves that must be eliminated to progress between locations. Elimination counts correspond to specific locations, requiring attention to this detail. The Lion challenge differs significantly – position yourself within emerging green orbs allowing souls to depart toward the main orb.
Eventually, orb reactivation becomes possible, though some players report interaction latency issues during testing. Persistence proves challenging during advanced rounds with increased difficulty.
After completing this segment, transport the Orb to the mural location for placement. This initiates a fresh cutscene enabling Guardian Key acquisition from the table.
To commence the boss encounter, carry the Guardian Key toward spawn location to the fountain area. The fountain contains the guardian as statue formation. Applying the Guardian Key animates the Guardian, triggering ground impact that teleports your team to the boss arena for confrontation.
Our observation revealed that Guardian stomp attacks can be deflected using your swords. Maintain persistence, evade attacks consistently, and sustain damage application against the massive opponent to achieve completion efficiently.
Boss Strategy: Designate one player as dedicated sword defender to counter stomp attacks while others focus on damage dealing. Rotate this role during cooldown periods to maintain optimal team survival.
Advanced Tactic: Save insta-kill power-ups for the final boss phase to maximize damage windows when the Guardian becomes vulnerable after specific attack animations.
Rewards and Pro Tips
The exclusive Calling Card unlocks only through main quest completion before Directed Mode implementation – anticipated during Season 2 update around January 2025 conclusion. Directed Mode facilitates main quest guidance, permitting Jackknife Weaver skin acquisition but excluding the special Calling Card reward.

Pro Completion Tips: Begin your Easter egg attempt with a dedicated team using microphone communication. Assign specific roles (symbol memorizer, zombie trainer, objective completer) to streamline complex puzzle sections and reduce completion time by 30-40%.
Avoid These Common Errors: Don’t attempt the Easter egg beyond round 25 without packed weapons. The increased zombie health and speed make several steps nearly impossible without upgraded firepower and specialized ammo types.
Speedrun Strategy: Optimal completion occurs between rounds 15-20 with pre-planned routing. Memorize symbol sequences beforehand and use stun grenades to control zombie movement during precise puzzle interactions.
