Black Ops 6’s climactic Season 5 introduces Reckoning, the ultimate Zombies experience that concludes the narrative arc. This final chapter delivers significant storyline revelations that will shape future Zombies content. While preserving major plot spoilers, this comprehensive walkthrough provides the exact methodology to conquer Reckoning’s primary Easter egg challenge.
Following the pattern established by previous maps, successfully completing Reckoning’s storyline quest grants exclusive cosmetic items. Your rewards include the distinctive “Blood, Sweat, An’ Gears” operator skin for Elizabeth Grey, an embossed calling card with special stamp recognition, and 5,000 XP towards your progression.
Note that the upcoming Director mode guidance feature, scheduled for the midseason update, will not provide access to the operator skin or the stamped calling card. Only by meticulously following this guide can you secure all unique permanent unlocks.

Strategic loadout selection dramatically impacts your Easter egg completion efficiency. Begin matches with high-capacity assault rifles or light machine guns to maintain sustained firepower during complex steps. The Maelstrom shotgun emerges as a community favorite when equipped with Rapid Fire mods and optimized attachments for close-quarters dominance.
The Aether Shroud field upgrade proves invaluable for creating breathing room during intense sequences. Its temporary invisibility and movement speed boost can save runs during critical moments when overwhelmed by zombie hordes.
Acquiring the map-specific Gorgofex Wonder Weapon represents a non-negotiable prerequisite. Consult our dedicated Weapons Unlock guide for detailed acquisition methods. These steps become accessible immediately after activating the map’s power system. In four-player cooperative sessions, designate one teammate to pursue the Wonder Weapon while others progress initial objectives.
During early Kommando Klaus special rounds—distinct zombie waves featuring aerial Klaus robots—you must collect two detached Klaus arm components they release upon elimination. These mechanical fragments serve essential functions in subsequent assembly phases.

Initiate the proper Easter egg sequence by activating the map’s primary power source. The game interface provides clear orange objective markers directing you to the power activation chamber and Pack-a-Punch station location.
Around rounds seven or eight, the Geneticist Zombie spawns within Mutant Research. Eliminating this special enemy yields a Keycard item essential for accessing secured containers in the area. Retrieve this keycard to unlock the containment unit and obtain the crucial DNA Vial.
Simultaneously, interact with the white canister depicted above to acquire a syringe. Transport both items to the Pack-a-Punch facility after establishing power connectivity.


Progress through the Teleportation Lab using scanner access, then locate the computer password from environmental clues including dated notes. This progression system integrates seamlessly with our Complete Guide methodology for systematic progression.


Assemble Klaus utilizing the collected arm components and structural parts discovered throughout the facility. This robotic ally becomes instrumental in navigating later challenges and accessing restricted areas.


Acquire cerebral matter for Klaus by targeting specific weak points with your Wonder Weapon, then purify the specimen using cleaning stations found in maintenance areas.


Final preparation involves activating the crystal portal mechanism and deploying vacuum seal canisters to stabilize dimensional rifts. This preparation phase directly influences the subsequent boss encounter dynamics.


Cooperative teams should implement specialized role assignments: one player focuses on objective progression while another handles zombie crowd control. This division of labor maximizes efficiency during complex multi-step processes. For optimal Class Guide integration, designate support players with healing abilities and offensive specialists with maximum damage output.
Common execution errors include neglecting Klaus arm collection during early rounds and insufficient Wonder Weapon ammunition preparation. Always maintain backup weapons and ensure field upgrade charges are available before initiating boss sequences.
Time investment varies significantly based on team composition and player skill level. Solo attempts typically require 45-60 minutes, while coordinated four-player teams can complete the Easter egg in 25-35 minutes with proper planning.
Advanced players should prioritize Pack-a-Punch upgrades before round 10 and maintain strategic positioning during Geneticist Zombie encounters to minimize unnecessary damage intake.
