"KGB-Spetsnaz Omega Group seeks to harness the energies and resources of the Dark Aether to give the USSR a strategic advantage over their Cold War foes - the Americans and NATO."
— Background

Omega Group, also known as KGB Special Operations Group Omega and Spetsgruppa Omega (Russian: Спецгруппа Омега, lit. Special Group Omega), is a covert KGB/Spetsnaz-backed research and military organization featured in the Zombies mode of Call of Duty: Black Ops Cold War.



Omega Group was formed on August 30th, 1975 by KGB Chairman Yuri Andropov to identify, study, and weaponize psychotronic phenomena, ranging from biocommunications and bioenergetics. Members of the organization were comprised of specialists from Spetsgruppas Alpha, Vympel, and Smerch, most of which were tasked with conducting military-based operations, though a select amount of key personnel derived from previous experiences in other experimental research programs were tasked with investigating possible weapon applications from any exoscientific phenomena discovered.

While Omega Group's area of operations span over the entire world, details of their missions were left covert, so much so that both the Soviet people and the rest of the outside world were ignorant of the group's existence and intentions.

Early Work

Omega Group never managed to find a scientific explanation for psychotronic abilities, but still conscripted a handful of Russian citizens with genuine talents and turned them into intelligence assets. Their "gifts", however, were impossible to reproduce and all of the assets were either killed in action or suffered psychological breakdowns.

In April 1976, a suicide bomber was sensed by one of the Omega Group assets as they attempted to enter the Soviet embassy in Ho Chi Minh City; the terrorist was promptly stopped and detonated at the gate. In June of that same year, an Omega Group asset used their telepathic ability during a multilateral conference for European communist parties in East Germany and learned that several representatives from satellite states were uniting to extract concessions from the Soviet government. Using that information, Omega Group arrested the diplomats' families in their home countries and stopped the insurrection before it happened.

In April 1978, an Omega Group asset in the Soviet embassy in Washington, D.C. used their biocommunication skills to influence President Jimmy Carter into stopping the production of neutron bombs in the United States. The same month, another asset helped the People's Democratic Party of Afghanistan assassinate the Afghan president Mohammed Daoud Khan during the Saur Revolution. The asset however experienced a mental breakdown afterwards and was liquidated before she could defect to the British consulate in Kabul.

Omega Group was also involved in the assassination attempts of US President Ronald Reagan in March 1981 and Pope John Paul II in May 1981 as well as the assassination of Egyptian President Anwar Sadat in October 1981.

However, as a result of little funding from Andropov, none of Omega Group's initial projects were able to advance past the research phase; due to this, the CIA would write off Omega Group in 1981, believing that their projects were abandoned. Consequently, all of the assets involved with Omega Group's psychotronic operations were ultimately liquidated following the death of General Secretary Leonid Brezhnev in November 1982.

A New Arms Race


On March 23rd, 1983, Ronald Reagan announced the Strategic Defense Initiative, which if implemented, could have posed a mortal threat to the Soviet Union. Two days later, the new KGB Chairman, Viktor Chebrikov, assigned Colonel Lev Kravchenko to revitalize and restore Omega Group to full readiness in order to offset the threat posed by the SDI. The very next day, Kravchenko ordered the unit's Research and Development team to scour NKVD and KGB archives. Omega Group was reorganized with Kravchenko's right-hand man Gorev serving as Tactical Operations Lead, with Captain Sergei Ravenov, a highly-regarded member of Spetsgruppa Alpha and with fierce loyalties to the Soviet Union, assisting him in preparing soldiers to Kravchenko's standards. The Psychotronic Phenomena Research department was led by Doctor Aleksandra Valentina, who continued Omega Group's original mission of studying "exoscientific phenomena" including extrasensory perception, telekinesis and pyrokinesis. An American defector and former weapons researcher at DARPA, Doctor William Peck, was chosen as the leader of the Exoscientific Phenomena Research department to develop military applications for any discovery made by Omega Group.

On July 15th, after four months of digging through the archives, Valentina discovered two reels of film sealed within an intelligence vault since 1945. The films were recorded at an abandoned German facility in then-occupied Poland called "Endstation"; the supernatural contents of the films are immediately flagged by Chebrikov for review. On August 2nd, Chebrikov met with Andropov, the new General Secretary, and other high-ranking officials of the Politburo for a screening of the films. During the meeting, it was proposed the subsequent weaponization of the phenomena recorded at the Endstation.

Operation Undertaker

Two weeks after the meeting, Operatsiya Grobovshchik, also known as Operation Undertaker, was authorized and Omega Group was given command of the operation. On August 28th, the long-abandoned Projekt Endstation facility and its surrounding territory was secured, using a cover story about unexploded ordnance to keep the locals away. Valentina and Peck soon began examination of the abandoned German technology throughout the facility, intending to repair the damage done by the Soviets in 1945 who sought to deactivate the facility's cyclotron. After two months of work, Omega Group were able to restore the facility to an operational condition, and were prepared to reactivate the cyclotron to recreate a gateway to the Dark Aether; during this time period, Kravchenko sent additional troops to the Endstation facility to assist in the reactivation of the particle accelerator.

On November 1st, Omega Group soldiers Orlov and Medvedev were tasked to restart the cyclotron, and although the two would perish in the attempt, Orlov was successful, which resulted in the creation of a new rift to the Dark Aether. However, unlike what happened during World War II where only a localized rift was opened, additional dimensional breaches, also called "Outbreak Zones", started to appear around the world: in a rainforest near the Orinoco in Venezuela, in a remote section of the Namib desert in Namibia, in the Thừa Thiên Huế Province in the Socialist Republic of Vietnam, near Baku in the Soviet Republic of Azerbaijan and a massive breach in the Ural Mountains. Omega Group managed to secure and contain the dimensional breaches in Vietnam and Azerbaijan over the next few days while monitoring the super-breach in the Ural Mountains.

With Operatsiya Grobovshchik being declared a "resounding" success, Omega Group moved to the next step of their plan: a thorough study of the Dark Aether and the subsequent development of new technologies and weaponry based on Aetherium.

Aetherium Research

A week after the reactivation of the Endstation cyclotron, Chebrikov formed a pact with Vietnamese Chairman Phạm Văn Đồng to establish an Omega Group research facility, called Outpost 25, at the former site of Firebase Ripcord in the A Shau Valley, using the cover story of a recently discovered US chemical weapon being detonated within the vicinity to drive away any unwanted attention. Omega Group noted that the dimensional membrane instability in the region that resulted after the initial breach suited their project of opening stabilized gateways to the Dark Aether operating under their control. On November 11th, the construction of the facility began with Doctor Peck assigned as its lead scientist.

On December 8th, Peck designed the Omega Portal Chamber, a large dome-like structure for a stabilized gateway and a month later, on January 8th, 1984, Peck and Doctor Dimitri Kuhlklay managed to create a new and stable rift to the Dark Aether using an Aetherium sample recovered from Projekt Endstation. Teams of Omega Group soldiers were now sent daily to the Dark Aether to collect Aetherium crystals using canisters specifically made to contain the radiation; biological, botanical and geological specimens, as well as liquid samples, were among the various otherworldly commodities being harvested. Peck noted that Aetherium could yield massive amounts of energy and could be used as a sustainable power source, and soon designed an Aether Reactor using refined Aetherium as fuel; by early February, Outpost 25 was entirely running on three seperate Aether Reactors.

Unfortunately, excursions in the Dark Aether proved extremely dangerous and Omega Group suffered heavy losses among their ranks. To address the problem, Kravchenko requested the conscription of Aetherium miners, dubbed "Aethernauts". The request was approved, and by early March 1984, prisoners from work camps started to arrive at Outpost 25, comprised of common criminals, political dissidents, foreign prisoners, and intellectuals from both the Soviet Union and Vietnam.

As more Aethernauts were sent to the Dark Aether, the collection of Aetherium crystals was up 237%. Excursions, however, were still incredibly dangerous, with a quarter of Aethernauts sent to the Dark Aether never coming back. Side effects from journeys in the other side also started to appear. Effects varied from individual to individual, with some people staying healthy while others exhibited mild radiation poisoning or returned fully necrotized. Multiple and/or prolonged excursions in the Dark Aether increased the likelihood and severity of the symptoms, especially for miners who encounterd hostile creatures or consumed food or drinks found in the other dimension. Kuhlklay also noted that some individuals suffered long-term memory losses. To circumvent this, Peck developed a memory transference machine, hoping it would restore the fractured minds of their conscripts. Peck also developed a truth serum to help recover memories and debunk conflicting reports.

On March 14th, Omega Group established five new Operatsiya Inversiya test sites in an effort to open and control additional dimensional breaches; of the five, four are successful. Simultaneously, Peck and Kuhlklay created the blueprints for the Red Soldier Mechanized Armor to help assist in the protection of Aethernauts, though Kuhlklay is later discredited by Peck and removed from the project. On March 19th, the first successful teleportation test was achieved at Outpost 25 and soon after, two teleporters were installed connecting the facility to a Vietnamese village occupied by Omega Group. On April 2nd, Omega Group began the next phase of their plan involving Operatsiya Inversiya: the process of weaponizing breaches in the form of long-range missiles for strategic strikes against the West.

On April 8th, Kuhlklay developed an Aetherium-powered assault rifle, the RAI K-84, but was scolded by Peck for wasting their time. In early May, Kuhlklay and Peck performed an autopsy on a Dark Aether creature which was captured a few days prior, though it was soon terminated when it tried to escape containment after turning itself into a rifle. Upon examination, Kuhlklay recognized a human face on the creature which he identified as Private Glaskov, an Omega Group soldier that went missing in the Dark Aether over a month prior. On May 11th, Omega Group completed canvassing for potential Operatsiya Inversiya targets, and on June 3rd, a report is sent to the Kremlin by Valentina for feedback. Of the proposed targets, Washington, D.C. and Manhattan, New York is approved; in a personal log, Valentina later expressed her dismay with the exclusion of Berlin, a target she stated would have been beneficial for her work there.

Fall of Outpost 25

On May 14th, after a visit from Gorev, Peck became aware that Samantha Maxis, a former agent of the BND, wished to expose Omega Group and was going to meet a mole from Outpost 25. Maxis was the individual who supplied the CIA with intel regarding Projekt Endstation and Operation Undertaker which led to the creation of the Office of Requiem to stop Omega Group in this new arms race.

Unbeknownst to Peck and Gorev, the mole was none other than Ravenov, who became appalled by Omega Group's research and the treatment of soldiers and prisoners in order to harness and weaponize Aetherium. Ravenov planned to deliver some of Peck's research to Requiem during his meeting with Maxis. However, Maxis was captured in June as part of Gorev's plan to uncover the mole inside Outpost 25. Following her capture, Ravenov contacted Grigori Weaver directly to inform him about the situation. Weaver and the other Requiem senior staff started working on a way to save Maxis while raiding Outpost 25 of Omega Group's Aetherium research.

Maxis was brought to Outpost 25, where Peck personally interrogated and tortured her to get information on the mole. Upon refusing to cooperate and withstanding torture, Maxis was thrown into the Dark Aether by Peck. Soon after, the gateway in the Omega Portal Chamber released a massive burst of Aetherium which contaminated the entire facility. As the infection spread quickly, a phasic barrier started to surround the base, which led to the death of anyone trying to cross it. Various temporary dimensional breaches also appeared around the facility, releasing large quantities of the undead. Peck soon sent a distress signal to Omega Group HQ, believing to be the sole survivor, as he was unaware Ravenov also survived.

Requiem launched Operation Lost Property to rescue Samantha Maxis, and its strike team arrived at the facility on June 15th, 1984. After meeting with Ravenov, the team reactivated the facility, unwittingly assisting Peck, who transmitted all of his research from Outpost 25 back to Omega HQ. The team was succesful in bringing back Maxis from the Dark Aether, but had to fight off an Orda before exfiltrating. While Samantha joined Requiem, Ravenov rejoined Omega Group and warned the team of an operation in the Ural Mountains.

By the time Requiem had left Outpost 25, Omega Group soldiers led personally by Kravchenko and Valentina arrived to extract Peck; as a test to prove his commitments to Omega and as punishment for letting Outpost 25 fall, Kravchenko stabs out one of Peck's eyes.

The Ural Mountains

Following the loss of Outpost 25, Omega Group shifted its primary interests to the Ural Mountains, the site of the world's largest Outbreak Zone that has been loosely contained since the activation of the cyclotron. On July 8th, Kravchenko assigned Peck to the Ural Mountains to assess the applications of the Aetherium crystals present at the site under the direct supervision of Gorev. Three days after arriving, Peck deduced that the Ruka site and the unique specimens present around the zones would allow Omega Group to advance Operatsiya Inversiya and develop the specialized warheads needed for it.

On July 14th, Peck created the blueprints for the Reality Inversion Warhead, which could generate dimensional breaches up to 500 meters, creating an estimated Outbreak Zone the size of 800 kilometers; using Tempests infused onto the heads of each missile, Omega Group would utilize their electromagnetic abilities to bypass Western warning systems to allow the missiles to reach their targets unimpeded, ensuring maximum damage that would be the catastrophic deathblow to the West. On July 22nd, Kravchenko assumed command of Operatsiya Inversiya from Valentina, which she feared would derail the plans she was conspiring with an enigmatic voice from the Dark Aether. On the following day, Valentina created the blueprints for the Beacon Communications Receiver, allowing for disclosed communications when paired with the mysterious Beacon device appearing in the Outbreak Zones.

Over the next few months however, Omega Group began to learn of higher otherworldly entities within the Dark Aether seemingly building up their forces; during an examination of a destroyed Krasny Soldat, Peck discovered that the armor, while of his design, was being altered and upgraded by unknown forces within the Dark Aether. Additionally, Gorev discovered from reports from his men that the Dark Aether Power Nodes in the regions were terraforming them, slowly expanding the sizes of the phasic barriers in the zones and allowing them to become more hospitable for the undead within them. Finally, an Omega Group mole embedded in Requiem's senior staff confirmed the existence of a singular entity ruling from the deepest part of the Dark Aether to Kravchenko, forewarning him of its impending arrival to reality should they continue their work. On September 3rd, Peck detailed some of the few bizarre occurrences happening throughout the zones, one being the appearance of a strange computer emitting a voice he would frequently talk to, asking it questions regarding the Dark Aether.

On November 15th however, Omega Group's plans with Operatsiya Inversiya would be severely derailed; Ravenov, who managed to rejoin Omega Group's ranks without being outed as the traitor, informed Maxis of the great threat Operatsiya Inversiya posed through intel leaked to him discreetly by Valentina. To ensure the plan never succeeded, Maxis made secret contact with the Requiem strike team fighting in the Ural Mountains, convincing them to briefly go behind Requiem's backs to meet with Ravenov at the Ruka silos and assist him with the destruction of Operatsiya Inversiya. Once the strike team made contact with Ravenov, they retargeted the launch of the warheads, sending them to the Pacific Ocean to ensure neither Requiem nor Omega Group possessed such weapons of mass destruction. With the fallout of Operatsiya Inversiya, dissent and division bloomed within Omega Group's ranks; some worried of the current situation and the reaction of the KGB, while some planned on defecting to Requiem with Ravenov's assistance, who was now disavowed and marked as an enemy of the state by the KGB for his betrayal. On November 30th, Omega Group attempted to salvage the Inversion warheads from the ocean, to no avail.

Unfortunately for the defectors, Kravchenko would catch wind of their plan, and tasked Doctor Hugo Jager to go undercover amidst the defectors and kill them all for their betrayal while setting up a trap for Requiem's strike team. Jager succeeded in his mission, leading to the deaths of all of the defectors and preventing Requiem from securing valuable intel regarding the Aetherium Neutralizer. Additionally, Requiem's strike team would be captured personally by Kravchenko and his forces at the monument at Sanatorium.
