The Umbrella Caucasus Research Facility was the site of the Umbrella Corporation's Russia branch, and the headquarters of Sergei Vladimir, commander of the secret underground research facility. As part of Umbrella Europe, this facility was of dire importance to Umbrella as it maintained an extensive B.O.W. research, development and production program which allowed the corporation to sell their bio-weapons in secret. It was Umbrella's newest and last facility. 1
History
The facility was originally a chemical plant run by the Russian government and built during the Soviet era. The overground buildings were originally the factory's main function. Following the end of the Cold War, it was abandoned by the Russian government and was later bought outright by Ozwell E. Spencer. After the purchase, Umbrella rebuilt the factory and used it as camouflage while building an expansive laboratory deep underground in 1998 after Spencer invested a significant amount of capital into its construction. 2 Many secret experiments were conducted at the facility, which also operated as the main mass-production plant for many of Umbrella's B.O.W.s, becoming a vital part of Umbrella's underground operations. Among the weapons produced here included the Hunter, Chimera, Licker and Umbrella's ace-in-the-hole, the T-A.L.O.S. project. The Red Queen and U.M.F.-013 retrieved from Raccoon City was also stored here until 2003, along with Umbrella's entire infrastructure. With the help of the Red Queen, Sergei continued to develop T-A.L.O.S.
On Feburary 18, 2003, the facility was raided by a private anti-bioterrorism unit led by Chris Redfield and Jill Valentine. As well as this team, Albert Wesker also led a one-man assault on the facility in search of Umbrella's infrastructure. Wesker leaked the t-virus throughout the facility, killing all of the staff and intending to escape with Umbrella's data. The facility's entire stockpile of B.O.W.s were also released. Chris and Jill managed to destroy the T-A.L.O.S. prototype, and Sergei himself was killed by Albert Wesker. A clean-up was commenced on the facility following the incident by a local anti-biohazard unit.
