Call of Duty®: Black Ops 3 „Zetsubou No Shima“ Easter Egg Guide
Before players can really dig into the Easter Egg, they must restore power to the map. Restoring power in Zetsubou no Shima is a little bit different than how power is restored in Der Eisendrache and other Zombies maps. To begin the power restoration process, the first step is to locate a bucket. Buckets are scattered all around the Zetsubou no Shima map and seem to spawn in random locations, so keep an eye out for one.
With a bucket in tow, check out the map located near the beginning, and note the locations of Lab A and Lab B. Spend some time getting points by killing zombies, and use those points to gain access to each lab area. In Lab A, use the bucket to collect the purple water, and take that water to the generator. In Lab B, do the same thing with the green water. This part is timed, so if the Lab B generator isn’t activated quickly after the Lab A generator, this step will need to be repeated.
The power will now be on temporarily, but we need it to be on in a more permanent capacity. To accomplish this, go to the left of the bunker area, and go underwater. Check to see if there is an underwater Pack-A-Punch machine to know if it’s the right spot. Slash away the webbing here, and go through.
Zombies will start to attack underwater, so kill them. Go up for air if needed, but when all the zombies are dead, the path to the power switch is clear. Flip the main power switch to permanently restore power to the entire Zetsubou no Shima map.
With the power on, visit the ritual site (use the map at the beginning to locate it) to find four black skulls. Each skull has a symbol on it, which corresponds to one of the four altars around Zetsubou no Shima. The altar sites are located at the spawn, at the docks, at the plane wreckage, and in the Communications Center.
Place each skull at its corresponding altar. Anyone that completed the Shadows of Evil Easter Egg should be able to guess what happens next. Simply stand by the altar and shoot the zombies that spawn. An audio cue will indicate when the skull is ready to return to the ritual site. Repeat the process for the other three skulls.
This will allow access to an underground area where the Skull of Nan Sapwe is located. Stand near the skull and shoot the ghost-like Keeper creatures that spawn. Another audio cue will signify that the Skull of Nan Sapwe is ready to collect, so pick it up to move on to the next step of the Easter Egg.
With the Skull of Nan Sapwe in tow, return to the ritual site and check out the pillar with the yellow, glowing icons. This pillar has three randomized challenges to complete, which consist of basic tasks like using traps to kill zombies or killing a certain number of zombies underwater. This step of the Easter Egg is pretty simple in that one simply has to complete the challenges as outlined, and then return to the pillar for a reward. Do this three times (when playing in co-op, each player has to complete the challenge) to complete this step of the Easter Egg.
In Zetsubou no Shima, the KT-4 is a weapon that can be crafted by acquiring three different parts and combining them at a workbench. The first part needed is a green test tube, which will be in the possession of a random zombie that will only spawn once the power has been turned on. Just keep an eye out for the test tube when killing zombies, and there should be minimal headache in acquiring it.
The second item needed to build the KT-4 weapon is a canister of purple spider venom. This canister can be found in Lab A. Go there and use the control panel to lower a cage. Lure a spider into the cage during one of the spider rounds, and then use the control panel to send the cage back up. Venom will be extracted from the spider, and the canister will be ripe for the taking.
The final item necessary to build the KT-4 is a red plant located deep underwater. Head to the underwater caverns and follow the blue rocks until red plant is found. Now head to the workbench (located in the basement of the bunker) and use it to build the KT-4.
We will upgrade the KT-4 a little bit later, as the upgraded KT-4 is required to complete the last step of the Easter Egg. In the meantime, we also need to build a zombie shield. The first part is in Lab B, the second part is in Lab A, and the third part is on the roof of the bunker. The exact locations of these parts in these areas is random each time.
With the parts necessary to build the Zombie Shield, head to a workbench and cobble them together. The next step is to electrify it, so return to the ritual area. Wait for lightning to strike, equip the shield, and then walk through the electricity. The electrified zombie shield and the upgraded KT-4 won’t be needed until a little later, but it’s good to get both items built early on in the Easter Egg.
One of the main purposes of the KT-4 weapon (and its upgraded form, the Masamune) is to gain access to previously inaccessible parts of the map. Now that we have it, we can face the giant spider boss, which needs to be killed to upgrade the KT-4 later on, and for progressing to the next step of the Easter Egg.
To find the giant spider boss, go to Lab A. At the back of Lab A is a blue spiderweb that can’t be cut down with the knife. Shoot it with the KT-4 to destroy the spiderweb, and move through the cavern on the other side to reach the boss. As far as bosses go, the giant spider boss is a bit easier than ones encountered on previously, and anyone that took out George A. Romero in Call of the Dead should have no problem felling the beast.
The trick to defeating the giant spider boss is to just shoot directly at its mouth with the most powerful weapons available. Once it is dead, examine its body to get the Spider Venom that will be used later to upgrade the KT-4 into the Masamune. Move beyond the giant spider boss to snag a free perk in the form of the Widow’s Wine, which will be useful for completing the rest of the Easter Egg.
With the spider venom in our possession, there are only two other items needed to upgrade the KT-4 into the far more powerful Masamune. The next item we’ll want to collect is the blue plant, the process of which can be seen in the video above. Basically, one has to collect rainbow water from the sewer pipes, go to where the red plant was found, scan the wall here to reveal a secret area, plant a seed, and use the rainbow water to water said seed. Do this for three rounds in a row, and a blue plant will grow from the seed. Collect it, and then move on to collecting the skeleton vial.
The electrified zombie shield will come in handy when it comes to getting the skeleton vial. Return to Lab B and bash the electrified zombie shield on the cage’s control panel. This will allow access into the cage, and into the underground tunnel beyond it. Here the skeletal remains of some unlucky soul will be found, and lodged in the skeleton’s rib cage will be the skeleton vial.
With the spider venom, blue plant, and skeleton vial, the KT-4 can now be upgraded to the Masamune. Simply take the KT-4 back to the workbench where it was originally built, and there will be an option to upgrade it to the Masamune.
With all that accomplished, we’re ready to start really digging into the meat of this Easter Egg. At this point, it would be smart to have a few perks and some upgraded weapons, because it would be disheartening to fail at this stage in the Easter Egg, to say the least.
Anyway, this is one of the longer steps in the Easter Egg. First off, go to the bunker, and scan the wall near the purple water using the Skull of Nan Sapwe. A poster will appear on the wall. After that happens, go back to the bunker’s entrance, to the room with the Gobblegum machine. Scan the wall on the left side of this room using the Skull of Nan Sapwe to reveal the generator room.
Now, plant a seed somewhere and water it with blue water, plus give it a shot with the Masamune. Do this for the next three rounds while going after the first two cog pieces (which we’ll explain how to get shortly) needed to repair the generator and gain access to the elevator. It shouldn’t take three rounds to get the first two cog pieces, but it’s a good idea to start this process now as to avoid pushing the game into even higher and more difficult rounds.
Whoever has the Anywhere But Here! Gobblegum should use it now. This will teleport everyone to a weird room with a dragon egg in the center. Check the room for the first cog needed to repair the generator.
Upon returning to the main map, head to Lab A. Go to the zipline, and smash the control panel with the electrified zombie shield. A secret platform will reveal itself about halfway down the zipline. Use the zipline, and then melee when positioned right above the newly revealed platform. The second cog piece will be located here.
Hopefully at this point, the plant is fully grown, or at least close to it. Again, to grow the plant, water it with blue water and shoot it with the Masamune for three rounds. Once the plant is fully grown, an anti-aircraft round can be harvested from it. Collect the AA shell and take it to the AA gun located at the bunker. Use the AA gun to shoot down the plane that appears every few rounds. If the shot misses, don’t fret; just grow another anti-aircraft round and try again.
With the plane destroyed, go to wherever it crashed and search the wreckage for the final cog. Take all three cogs to the generator, and insert them to activate the elevator.
Take the elevator to the bottom and use the Masamune to clear the way to the boss. Like the giant spider boss from earlier, this boss – the Thrasher – is not all that difficult, but having Juggernog, the Masamune, and other upgraded weapons will certainly make things easier. To start the boss fight, blast the large spore on the Thrasher’s arm.
To damage the Thrasher, simply shoot the remaining spores on its body with charged Masamune shots. What makes this encounter more difficult, however, is that zombies and spiders will enter the fray in waves. The Thrasher is less likely to down players than those creatures, so they need to be dealt with before worrying too much about dealing more damage to the boss.
With a little bit of persistence, the Thrasher boss will be defeated. At that point, the ending cut-scene for Zetsubou no Shima will play. Watch the finale right here, just in case going through this massive Easter Egg seems like more of a time commitment than it’s worth:
With yet another massive Black Ops III Easter Egg complete, players should unlock the Seeds of Doubt trophy, and be ready to tackle the next expansion, which should be available in a couple month’s time. Having said that, while this guide does walk players through the biggest Zetsubou no Shima Easter Egg, the revelation that the first Call of Duty Zombies map still has undiscovered Easter Eggs means there could possibly be even bigger secrets that players have yet to discover in Black Ops III‘s latest expansion.
