Call of Duty: Black Ops 3 Zombies features one of the most atmospheric and complex maps in the franchise with Zetsubou No Shima. Set on a remote Pacific island overrun by Division 9 biological experiments, this map introduces intricate setup processes, unique Wonder Weapons, and plant-based mechanics. Mastering this location requires careful planning and a strong understanding of how power, rituals, and quest steps function together.

Restoring Permanent Power to the Island

Restoring power on Zetsubou No Shima is a multi-step process that differs from traditional map layouts. Players must first fill temporary generators at Lab A and Lab B using bucketed water collected around the swamp. Once both lab generators are temporarily charged, accessing the underwater bunker allows players to clear stuck debris from the main generator turbine to establish permanent power.

Maintaining constant awareness of your environment is crucial while navigating the flooded corridors of the bunker. Submerged paths can lead to secret areas, key quest parts, and essential perks that help you survive high-round encounters. Securing permanent power early gives your team access to crucial crafting benches, doors, and GobbleGum machines needed for long-term survival.

Building the KT-4 Wonder Weapon

The KT-4 is the signature Wonder Weapon of Zetsubou No Shima and acts as a vital tool for both defense and Easter Egg progression. Crafting this weapon requires three distinct components: a plant element grown with underwater light, a vial obtained from a special zombie, and an element harvested from a spider boss. Assembling these parts at the subterranean workbench yields a powerful weapon capable of dissolving hordes of undead.

Upgrading the KT-4 into the Masamune requires completing individual player challenges, obtaining special rainbow water, and retrieving an underwater plant. Utilizing effective strategies during these steps keeps the team alive while handling elite Thrashers. Players often rely on advanced tactics to streamline setup phases and survive challenging rounds efficiently.

Unlocking the Skull of Nan Sapwe

The Skull of Nan Sapwe serves as a powerful specialist weapon that can vaporize surrounding enemies or mesmeric reveal hidden clues around the map. To unlock it, players must interact with four altars located across the island and transport their corresponding skulls to designated ritual pillars. Clearing the waves of foliage-corrupted zombies at each pillar cleanses the skulls for final placement.

Once all four cleansed skulls are returned to the central altar, a subterranean chamber opens up to reveal the weapon. Defeating the protective keepers inside awards the Skull of Nan Sapwe to all players in the match. This weapon is crucial for revealing hidden doorways, charging special plant setups, and completing the map's main storyline quest.

Thriving in the Island Environment

Surviving high rounds on Zetsubou No Shima depends heavily on utilizing the unique gardening mechanics effectively. By planting seeds and watering them across three consecutive rounds with specific water types, players can grow reward plants that yield free perks, weapons, or holding cells. Experimenting with different water combinations provides reliable resources without spending points at mystery boxes.

Managing spider rounds and Thrasher spawns requires careful ammo management and tight positioning around open training areas. The canopy zip lines and sewer pipe travel networks allow quick rotations when a area becomes overcrowded. With properly upgraded gear and strategic plant cultivation, players can comfortably dominate this challenging Zombies experience.
