"The Reactorniy Avtomat-Izluchatel Kuhlklay-84 (RAI K-84) was developed by Dr. Dimitri Kuhlklay and first manufactured in 1984. The experimental prototype fires fully automatic energy-bolts, but also comes equipped with a ballistic Vortex grenade launcher. When detonated, the grenade creates a temporal distortion field, slowing time for anyone caught inside. Acquired by Requiem agents for analysis."

The Reactorniy Avtomat-Izluchatel Kuhlklay-84 (Russian: Reactor Automatic Radiator Kuhlklay-84), shortened as the RAI K-84, is a wonder weapon featured in the Call of Duty: Black Ops Cold War Zombies map Firebase Z, and Outbreak experience.

Overview

The RAI K-84 is a slow firing automatic rifle combined with Aetherium technology that was designed by Doctor Dimitri Kuhlklay. The weapon fires purple plasma-like rounds with high power, in addition to being equipped with an underbarrel grenade launcher called the "GP-6K2" that fires small purple orbs reminiscent to the effects of the Ring of Fire ability at the cost of 10 rounds from the magazine. When an orb is shot by the RAI K-84 enough times while a zombie is within it, it will explode, dealing high amounts of damage to any nearby enemies within its proximity.

When upgraded via the Pack-a-Punch Machine, it becomes the Discordian Disruptor, gaining a magazine count of 50 with a reserve of 300, while the underbarrel launcher becomes the Discordian Harmonizer. In addition to increased damage, the rounds fired from the Discordian Disruptor and its underbarrel are now red as opposed to the RAI K-84's purple.

Acquisition

The RAI K-84 can be obtained from the Mystery Box, as a potential legendary reward from Trials, or by assembling one as part of a small quest. For the quest, there are various items the player must assemble.

Step 1

Once the player gains access to the Weapon Lab, the player can acquire the RAI K-84's blueprint from a wall above a workbench. Ravenov will tell the player about Doctor Kuhlklay, the weapon's creator, and instructs them to acquire a key from him.

Step 2

At the Scorched Defense lies the zombified body of Doctor Kuhlklay, laying against a burning vehicle. Upon approaching him, the player will be given a prompt to rip out one of Kuhlklay's eyes, which will start a small in-game cutscene that enables the player to be temporarily ignored by the zombies. While the player performs this action and rips out his left eye, the zombified Kuhlklay will awaken and snarl, causing the player to simply stab the undead doctor in the head with a knife. Afterwards, the player can bring the eye to Kuhlklay's computer in the Weapon Lab, where it can be placed in a retina scanner. Once the eye is scanned, a drawer will open, revealing a locker key that the player can pick up.

Step 3

With the locker key, the player can now open several lockers found within the two Barracks just beyond the Helipad. After opening some of the lockers, a Mimic will spawn nearby and attack the player. Upon killing the Mimic, it will drop the Barrel Assembly of the RAI K-84, which can then be picked up. Alternatively, if the Mimic does not drop the barrel, the player can continue opening more lockers until another Mimic spawns with the part.

Step 4

Next to the retina scanner is a computer, which is displaying a circular chart with part of the upper section highlighted. Interacting with the computer will cause a new section to move around the computer, stopping at three certain points that correlate to certain scores on the dart board found next to the Der Wunderfizz machine in the village. The player must memorize the positions that the section on the computer stops, then head to the aforementioned dart board and shoot the positions on the dart board where the section stopped at. After shooting all three, the player can shoot the center of the dart board, causing a secret compartment to open, which will spit out the RAI K-84's Aetherium Converter for the player to collect.

Step 5

The player must now wait until a Mangler spawns. When one does, the player must kill the Mangler by destroying its arm cannon while it is charging an attack. Doing so will drop an Uncharged Power Cell, which the player can bring back to the Weapon Lab and place in a charging slot to the right of the Arsenal machine. The player must now wait a couple of rounds for the power cell to charge; upon finishing, it will become a Charged Power Cell that the player can collect.

With all of the parts gathered, the player can assemble the RAI K-84 at a workbench to the left of Kuhlklay's computer.
