mission. Upon arriving in Berlin, Kravchenko and the strike team learn that Valentina has been mutated with Dark Aether energy by the Forsaken, the entity mentioned by Zykov, who was also masquerading as Vogel to trick Valentina into doing his bidding. The strike team reaches an abandoned CIA safehouse and reactivates Klaus, a combat robot customized with an artificial intelligence module created by the Director of Requiem. With Omega Group's instructions, the team constructs a miniature Aetherium warhead using components left onsite by the CIA. Valentina attempts to stop them, but is ultimately defeated, and her energy is used to refine the Aetherium for the warhead. As the Forsaken taunts Requiem of his imminent arrival, Klaus carries the warhead through the portal to complete the mission. Kravchenko attempts to betray the strike team at the last minute, but Maxis, using her Dark Aether power, manages to open a portal, allowing the team to return home safely. Meanwhile, the Director monitors Maxis, and sends a group memo to an unknown recipient, noting her growing power as a concern toward Project Janus. As Operation Threshold expands into the North Atlantic Sea and Algeria, the Director continues to pressure Maxis in isolation, coercing her into using her powers. Meanwhile, Omega Group authorizes a new operation to free Zykov from the Dark Aether, intending to use this opportunity to take down the Forsaken with their own warheads. Requiem, after receiving intel on Omega's new operation from Ravenov, also intends to free Zykov by their own means. On June 4, 1985, the Requiem strike team is deployed to an Omega test site in Ukraine, where Kravchenko and Peck are conducting the final steps to open a Dark Aether gateway. They succeed in freeing Zykov, only to learn that he was the Forsaken all along. As Kravchenko and Peck attempt to escape the facility, Maxis and the strike team make their final stand against the Forsaken. Eventually, Maxis sacrifices herself by plunging into a Dark Aether portal, weakening the Forsaken enough for him to be captured by Omega's containment chamber. With the Forsaken defeated, all global outbreak zones are collapsed, and the undead threat is contained. The Director - revealed to be Edward "Eddie" Richtofen - orders Requiem to be shut down, and its department leads apprehended alongside the strike team, while the Forsaken's chamber is delivered to an unknown location. Five years later, Peck travels
