Call of Duty: Black Ops 3 remains a high point for cooperative survival fans, largely due to the complex architectural design of its launch map, Shadows of Evil. Navigating the dark, Lovecraftian corridors of Morg City requires players to balance standard survival mechanics with intricate puzzle-solving elements. Unlocking the ultimate narrative conclusion of this cooperative mission requires a full squad of four coordinated survivors working toward the same goal.
Completing the Initial Four Gatekeeper Rituals
The journey begins with unlocking access to the Pack-a-Punch machine by collecting specialized golden artifacts belonging to each of the main characters. Survivors must assume the temporary form of the Beast to shock active electrical boxes, crack open hidden crates, and grapple onto distant platforms to lower the necessary quest items. Each collected artifact must then be taken to its corresponding altar location scattered across the Footlight, Waterfront, and Canal districts.
Initiating a ritual spawns dangerous ethereal Keepers that aggressively pursue players within a confined space for a limited time duration. Successfully completing all four ceremonies drops specialized gatekeeper worms and grants entry to the Subway area where the final ritual table resides. Placing the collected components onto this central shrine officially opens the rift portal and prepares the arena for advanced dimensional steps.
Building the Apothicon Servant and Upgraded Swords
Surviving the later rounds becomes significantly easier when players take the time to build unique elemental armaments scattered across the map. Finding the Margwa Heart, Xenomatter, and Tentacle parts allows groups to assemble the powerful Apothicon Servant wonder weapon at any localized crafting bench. This rare tool functions by creating temporary localized black holes that instantly consume massive crowds of approaching zombies.
Simultaneously, teams should focus on collecting the golden eggs located inside the rift area to begin upgrading their protective keeper swords. Players must place these heavy objects into specific statues located across the districts and charge them by defeating enemies nearby. Once fully energized, these ancient weapons transform into autonomous guardians that float alongside survivors to provide continuous defensive fire support.
Navigating the Shadow Man Final Confrontation
After completing the preliminary steps, players must locate hidden code symbols along the moving tram line to unlock the ancient Apothicon Keepers book. Returning this tome to the central ritual room initiates a challenging defensive sequence against waves of specialized enemies and elite Margwa bosses. Survivors must coordinate their primary ammunition pools to continuously drop the protective magical shields surrounding the deceptive villain.
Once the villain is vulnerable, players must quickly interact with the nearby altars to trap the entity within a localized summoning circle. Capturing this boss alters the ambient environment of Morg City, introducing an eternal purple night phase filled with constant environmental hazards. Teams must act decisively during this phase to maintain map control while setting up the final cooperative world puzzle.
Coordinating the Final District Train Step
The absolute final stage of the quest requires flawless communication as three players must position themselves at the electrical terminals located inside each major district train station. The final player remains in the central junction area to manage active beast fountains and control the global timing of the execution. Activated terminal nodes will send an intense surge of electrical current through the metallic tracks spanning across the metropolis.
When the grid is fully energized, the human characters must shock the physical tracks while the train is currently in active motion between hubs. Completing this simultaneous interaction successfully cleanses the skybox and unlocks the official cinematic narrative ending for the group. Mastering this multi-staged challenge rewards dedicated players with massive XP boosts and permanent bragging rights within the global zombies community.
