Conquering the Call of Duty: Black Ops 3 Zombies map Zetsubou No Shima requires a firm grasp of its dense swamp environment and complex puzzle mechanics. Players must brave mutated flora, aggressive spiders, and underground labs to complete the main storyline quest. This walkthrough breaks down each step logically to ensure your survival on this unforgiving Pacific island.

Essential Map Setup and Power Restorations

Before attempting the main quest objectives, activating permanent power across the entire facility is absolutely critical. Players need to collect distinct fluid canisters to temporary power two separate generator locations before the main bunker doors can open. Once inside the bunker, clearing the flooded pack-a-punch room allows you to permanently stabilize the facility's power network.

Building the map's unique wonder weapon early is highly recommended to ease the difficulty of later rounds. The parts are obtained by defeating a specialized spider boss, harvesting an underwater plant, and capturing a glowing yellow element. Assembling these components at the workbench provides your team with the essential crowd-control capabilities needed to survive high rounds.

Completing the Trials and Finding Key Artifacts

Progressing the narrative requires every player in the session to complete all three unique challenges displayed on their personal stone pillars. These objectives vary from shooting spore clouds to shooting specific targets around the swamp. Completing these challenges unlocks the lightning strike event, which is vital for upgrading your equipment later in the game.

Players also need to obtain the ancient skull weapon by cleansing four distinct ritual sites scattered across the island map. Charging the skull with trapped zombie souls unlocks an immense spiritual energy source that reveals hidden objects. This weapon is crucial for uncovering secret doorways and blinding powerful enemies during intense defensive steps.

Navigating the Final Boss Encounter

With all parts gathered and upgrades completed, players must use the charged skull to reveal a hidden elevator shaft deep inside the bunker. Descending into this subterranean cavern triggers a massive battle against a giant mutated creature surrounded by toxic spores. Utilizing the upgraded wonder weapon on the weak spots of the boss while managing the regular zombie spawns is the most effective strategy.

Maintaining absolute spatial awareness in this tight arena ensures your squad will not get trapped by aggressive thrashers. Once the creature is defeated, an emotional narrative cutscene triggers to reward your hard work and complete the level milestone. Surviving this final gauntlet cements your mastery over one of the most mechanically complex maps in modern gaming history.
