The Shadows of Evil map in Call of Duty: Black Ops 3 remains one of the most intricate and rewarding Zombies experiences ever created. Completing its main Easter Egg requires precise teamwork, deep map knowledge, and thorough execution of specific rituals. Understanding the foundational requirements before diving into Morg City ensures your squad is ready for the challenge ahead.

Essential Player Requirements and Preparation

Completing the main quest on Shadows of Evil strictly requires a full lobby of four players. While solo players can complete early stages up to trapping the Shadowman, the final climax cannot be triggered without four active participants. Teams should coordinate their loadouts beforehand to ensure adequate firepower and resource management.

Players should equip essential Gobblegums to facilitate quick progression through early rounds. Utilizing weapons like the KRM shotgun or high-capacity assault rifles helps handle Margwas and zombie hordes efficiently. Preparing team communication channels is equally vital for executing synchronized steps later in the match.

Performing Character Rituals and Unlocking Pack-A-Punch

The journey begins by gathering character-specific items across Morg City to initiate four unique rituals. Players must use Beast Mode to unlock access to ritual items like the Lawyer's Pen, Detective Badge, Championship Belt, and Hairpiece. Each item is placed on its designated altar to start a ritual that spawns Keepers and yields a Gateworm.

Once all four Gateworms are acquired, players must head to the Underground subway region through the Rift portals. Placing all Gateworms into the subway basins unlocks the Pack-A-Punch machine and transforms the city environment. This step opens up advanced upgrades necessary for surviving upcoming combat challenges.

Forging and Upgrading the Apothicon Swords

To acquire the powerful Apothicon Sword, players must ride the monorail between districts and spot glowing symbols out the window. Using Beast Mode in the Underground, players shock the matching symbols on the stone wall to reveal mystical eggs. Charging these eggs at four distinct Keeper statues across the map requires harvesting zombie souls.

Returning the fully charged eggs to the subway altar awards players their individual elemental swords. Players can then visit their character's original ritual site to collect an Arch-Ovum for the sword upgrade. Defeating Margwas at four designated red summoning circles completes the upgrade to the Reborn Sword.

Trapping the Shadowman and the Final Showdown

With upgraded swords equipped, players pick up the levitating book at Nero's Lair to trigger the Flag step. Squads must protect the flag at various lightning sites across all districts while defending against flying elementals and Margwas. Delivering the charged flag to each ritual site converts ghost Keepers into allies needed for the confrontation.

In the Pack-A-Punch chamber, players interact with the Keepers to drop the Shadowman's shield and trap him inside the Summoning Key. For players seeking further game guides, visiting provides additional gameplay insights. The final sequence requires three players in Beast Mode at tram stations to shock overhead boxes, while the central player shocks the sky Keepers as the tram crushes the giant worm.
