Where is the crafting blueprint for the Rai K-84 weapon in zombies on Firebase Z:
Once the power has been activated on the new Call of Duty Black Ops Cold War zombies map, you will need to go to the "Weapons Lab", there you will find a workbench with a wall chart, the weapon blueprint Rai K-84 will simply hang on this wall chart and you will only have to approach to pick it up and add it to your inventory.
★ Tip – If you have the possibility to craft the weapon by yourself with the blueprint you just picked up, be aware that this is not the only way to get Rai K-84 on Firebase Z. You can also find the weapon in the mystery box when you spend 950 points or with the sale, but it will then be necessary to rely on the "luck" factor. Similarly, you can obtain the weapon by completing computer challenges until you reach a legendary reward level. If these methods are too risky for you, continue below to find out how to craft the weapon.
Extract Dimitri Kuhlklay's eye and get the key:
Now that you have the plan, go to the "Fortification Blaze" area and approach where the carcass of a tank is. You will find the corpse of Dimitri Kuhlklay on the ground. It is always in the same place, it is not a random placement (but be careful, it does not appear until you have retrieved the weapon blueprint from the workbench). Approach the corpse to see the “extract the eye” interaction appear, you will then see an animation where your character will recover the eye of this Dimitri Kuhlklay. Once you have it in your hands, return to the "Weapons Laboratory" where you picked up the blueprint for the Rai K-84 weapon. You will see an old computer that will have its screen on (hence the need to turn on the power) with the message "Prove You Are Me" on the screen, you will then need to scan the retina of Dimitri Kuhlklay's eye via the scanner installed right next to it which will open a drawer under the old computer and allow you to retrieve the locker key (don't forget to pick up the item before leaving).
Open the lockers in the barracks and make the zombie imitator appear:
Exit the "Weapons Laboratory" and look for the two barracks facing each other, "Barracks 1" and "Barracks 2" where you will find beds and lockers inside. The key you just picked up will allow you to open the lockers. Your goal is to open them one by one until a Zombie Impersonator appears. Kill him to drop the cannon assembly piece. Be careful, you may not get the coin on the first copycat you kill… If that happens, you'll just have to go back and open the lockers to spawn another one until you can get the coin from assembly of the Rai K-84.
Solve the dartboard puzzle:
Go back to the "Weapons Lab" again and check the screen of the old computer again where you scanned the eye. You will then see a kind of graphic radar on the screen with a moving and flashing line. Pay attention, this line actually shows you a three-digit code. You have to memorize the areas where it flashes, because you will have to shoot the same places of a dartboard that is on a wall of the "village canteen" at the very beginning of the Firebase Z MAP where " Ravenov” (the guy behind the armored glass). Shoot not the numbers, but the lines of the three-zone dartboard that was indicated by the flashing computer graphic (the code is random and changes between each round). When you are sure of yourself, shoot one last time at the center of the dart board and a secret compartment will open which will allow you to retrieve the "Aether Transformer".
Kill Massacres and get the last piece of the K-84 Rai weapon:
Once you have completed the previous stages, then survive the zombie waves until slaughterers appear. You will have to eliminate them until you see the very last part you are looking for appear, the "discharged battery" which will allow you to finally be able to craft the Rai K-84 weapon. Similar to the zombie copycat story earlier in the guide, you'll likely need to kill several killers to see the "depleted battery" appear on the ground. The object is easily recognizable since it has a yellow appearance. Return to the "Weapons Lab" again and place the depleted battery in a dedicated device which is placed next to a computer screen and connected by a cable (there is also a large shell on the table that you can hard to miss). You will then have to survive two more rounds to turn the “depleted battery” into a “charged battery”.
Craft the Rai K-84 Prototype and get the secret weapon from Firebase Z:
If you got all the steps right, the time has finally come, just go back to the "Weapons Lab" workbench at the very place where you picked up the blueprint for the weapon at all. start of the guide and all you have to do is start crafting the Rai K-84 Prototype, which will allow you to add the Rai K-84 to your arsenal of weapons. Feel free to use its alternate fire mode to be able to achieve real carnage in the zombie ranks, D-Pad up on controller or B key on keyboard to use the incredible alternate fire mode of the Rai K-84.
