The KT-4 is the ultimate wonder weapon that you need to survive the higher rounds of Zetsubou No Shima in Call of Duty: Black Ops 3. Aside from the raw power, the wonder weapon has a bunch of uses that can help provide you with fertilized seedsand even complete the Easter Eggin BO3 zombies.
To holster this weapon, you’ll be required to find three parts scattered around the map which can surely take a while if it’s your first time. To assist you in crafting this buildable item, read our guide below.
How to get the KT-4 in Zetsubou no Shima
There are three parts that you need to find to build the KT-4 wonder weapon in Black Ops 3 Zombies. These include a green test tube, a purple container, and a red plant.
All three of these items require some sort of process to acquire, unlike the riot shieldthat gets built by locating the designated parts.
Green Test Tube
The green test tube is the first part that players should be looking for. It is an item dropped by killing one of the zombies glowing green. Simply kill the zombie and collect the item.
FYI
The green test tube is a random drop making it much harder to acquire. To increase your chances of getting the test tube, build the riot shield first and then go on the hunt for the item.
Purple Container
The purple container can be acquired by entrapping one of the spiders in the cage underneath of Lab A. To trap the spider, simply wait for round 5 where they spawn. Head inside the main Lab A and interact with the cage terminal to lower the cage and open it. Simply exit the lab and visit the cage.
Try to lure a spider into the purple smoke of the cage. Once that’s done, simply head back and interact with the terminal again to acquire the second part for the KT-4 wonder weapon in Zetsubou No Shima.
Red Plant
The last part of the wonder weapon can be found deep underneath the water inside the main bunker. After turning on the power, simply drop down to the lower floor where the Mule Kick is present.
In front of the vending machine will be a door that leads to the underwater area of the map. Purchase it and swim down until you reach a dead end with blue crystals to spot the red plant.
Now what’s left is to swim back up and head on over to the workbench in Lab A to build the KT-4 wonder weapon in Black Ops 3 zombies.
How to upgrade the KT-4 Wonder Weapon
If the regular KT-4 wonder weapon isn’t providing you with the kick you deserve, there’s a way to upgrade it and turn it into a more stronger version known as the Shima Masamune in Call of Duty: Black Ops 3.
Just as we built the weapon, the process of upgrading it remains the same. Find three parts around the map that are hidden behind a set of tedious tasks to be completed.
The green liquid can be obtained by killing the spider boss in its lair. Simply kill the spider and approach its dead body to find the green liquid inside of the body.
The yellow liquid can be obtained by completing the challenges at the skull of Nan Sapwe’s altar to get the electric shield.
Once the shield is acquired, head over to Lab B and bust the terminal with the electric shield to open up the cage. Get inside the cage and ask one of your teammates to interact with the terminal.
The terminal will cause the cage door to close and it’ll take you to an underground facility. While still in the cage, look for the small skull holding the yellow liquid. Simply press square to acquire the second part.
For the last part, you’ll be required to get the gold bucket that holds the iridescent water. Once the bucket is acquired, use the sewer system to get the iridescent water and return to the main bunker.
The next task will be to plant a seed inside the small underwater area where you found the red plant to build the KT-4 wonder weapon. Swim over there and look at the wall on the right to open a small area with the mud dug. Plant a seed and water it with iridescent for three consecutive rounds to get the blue plant.
Once all three parts are collected, head back to the workbench where you build the wonder weapon and apply the three parts to get Shima Masamune in Call of Duty: Black Ops 3.
