The Caucasus Laboratory was the base of operations of the Umbrella's Russian branch, and the headquarters of Sergei Vladimir, the facility's director. The facility was of dire importance to Umbrella as it maintained an extensive B.O.W. R&D and production program which allowed the corporation to sell their bio-weapons in secret. It was Umbrella's newest and last facility. 1
History
Purchase & Reconstruction (????-1998)
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 by Ozwell E. Spencer through a dummy corporation of Umbrella. 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 foreign capital into its construction. 2
B.O.W. Development & Production (1998-2003)
Many secret experiments were conducted at the facility, which also operated as a 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 were the Hunter, Chimera, Licker and Umbrella's ace-in-the-hole, T-A.L.O.S.. The RED QUEEN and U.M.F.-013 retrieved from Raccoon City were also stored in the facility after the city's destruction in October 1998. With the help of the RED QUEEN, Sergei continued to develop T-A.L.O.S.
By 2003, following the loss of many of their most precious customers and samples on the Spencer Rain in September 2002, Umbrella prepared for a revival once again by supplying its B.O.W.s to unstable regions around the globe while developing T-A.L.O.S. as the next top product on the B.O.W. market.
Operation T.A.L.O.S. (Feb. 18, 2003)
On February 18, 2003, the facility was raided by the Russian branch of the Private Anti-Bioterrorism Unit. As well as this team, Albert Wesker also led a one-man assault on the facility in search of the U.M.F.-013. Wesker leaked the t-virus throughout the facility, killing all of the staff and intending to take revenge on Sergei for interfering with his plans during the Mansion Incident. The facility's entire stockpile of B.O.W.s was released in the biohazard. 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 the soldiers.
