Mastering the complex puzzles of Morg City is one of the most rewarding challenges in Call of Duty: Black Ops 3 Zombies mode. The map features a dense atmosphere loaded with Lovecraftian elements and intricate multi-step objectives. Players must carefully coordinate their characters and manage their rounds efficiently to successfully banish the ancient evils looming over the metropolis.
Completing the Sacrificial Rituals
Before attempting the main quest line, your squad must gather four specific items tied to the characters and complete their respective rituals. You will need to utilize Beast Mode strategically across the Canal, Footlight, and Waterfront districts to open hidden rooms and secure the objects. Placing these items on the sacrificial tables triggers a wave of keepers that you must survive until the gateworm is revealed.
Once all four gateworms are collected, players must travel deep into the underground Rift area to open the final gateway. Placing the worms in the designated basins allows you to unlock the powerful Pack-A-Punch machine. This crucial weapon upgrading station prepares your loadouts for the extreme battles waiting in the subsequent phases of the quest.
Awakening the Reborn Swords
The next critical phase requires your team to locate glowing symbols while riding the monorail train across the city. By memorizing these distinct glyphs, you can access the underground wall in Beast Mode to open a chamber containing ancient elemental swords. Each player must grab their respective blade and proceed to charge it by defeating powerful Margwas around the districts.
After standard charging is complete, the swords can be returned to their corresponding ghostly Keepers to initiate the upgrade process. This requires standing inside specialized glowing circles on the map and surviving additional intense combat trials against multiple minibosses. The resulting upgraded swords provide massive offensive capabilities that are vital for the final encounters.
The Final Showdown and Apocalypse Averted
With fully upgraded armaments, the final phase shifts the focus directly toward defeating the elusive Shadowman in the Rift ritual room. Players must capture the Shadowman inside the Summoning Key while defending against endless waves of the undead. Constant communication and split-second timing are essential to trap the antagonist and progress the arena state.
The concluding step requires all four players to coordinate simultaneously in Beast Mode between the train stations and the junction plaza. Three players must shock the electrical boxes along the monorail tracks to turn the rails completely blue. Meanwhile, the final player must wait in the center to zap the floating keepers the exact moment the train squashes the giant worm.
