Zetsubou No Shima Easter Egg Steps And Full Walkthrough

The Zetsubou No Shima map in Call of Duty: Black Ops 3 Zombies remains one of the most mechanically complex experiences in the entire franchise. Navigating its dark, swampy island requires players to master unique environment mechanics, specimen management, and chemical mixtures. Conquering the main quest line rewards dedicated survivors with vital narrative revelations regarding the Primis characters.

Setting Up the Island Infrastructure

Before attempting the main quest steps, players must fully restore power to both major facility wings on the island. This process requires gathering dynamic harvest seeds dropped by defeated enemies and watering them over multiple rounds. Securing the specialized gas mask is also crucial to survive the hazardous underwater passages hidden below the bunker.

Building the specialized Shield and acquiring the KT-4 wonder weapon serve as the foundation for your survival strategy. These items are necessary to destroy the thick webbing blockades obstructing critical pathways around the map. Once the basic infrastructure is active, you can begin focusing on the specific trials required for the main ritual.

Completing the Trials and Acquiring the Skull

The next phase involves completing the individual challenges located at the ritual stone pillars scattered across the jungle. Each player must fulfill three distinct combat or survival objectives to activate their corresponding monument. Fulfilling these requirements grants access to the powerful Skull of Nan Sapwe weapon.

The Skull allows players to mesmerize hidden environment objects and reveal secret compartments built into the walls. You must use this spiritual energy to uncover missing structural blueprints and hidden poster locations inside the laboratory. Properly managing the weapon energy ensures you can progress smoothly without waiting for subsequent round shifts.

Growing the Ultimate Specimen Plant

The final puzzle element involves growing a massive underwater plant using three distinct sources of elemental water. Players must meticulously fetch blue, green, and purple glowing liquids from different sectors of the island over consecutive rounds. Additionally, the Skull must be used to mesmerize the soil bed to ensure the seed mutates correctly.

Once the specimen matures, it will hold a specialized artillery shell needed to disable the overhead anti-aircraft gun. Firing this heavy artillery at the proper moment brings down a distant plane carrying the final mechanical gear piece. Collecting this dropped wreckage allows survivors to fix the broken elevator mechanism and descend into the deep boss arena.

Surviving the Deep Underground Showdown

Descending into the lowest cavern triggers the final confrontation against a mutated giant spider creature trapped within the roots. Players must balance damaging the weak points of the boss while fending off infinite waves of smaller thrashers. Keeping the gas masks repaired and utilizing the fully upgraded Masamune weapon will maximize your team damage output.

Defeating the creature unlocks the secure holding cell containing Takeo Masaki double, completing the primary narrative quest line. Survivors are treated to an emotional cinematic sequence detailing the character inner resolve and spiritual sacrifices. Successfully completing this encounter also unlocks a permanent checkpoint achievement for the overall story progression.
