Caucasus laboratory

The Umbrella Russian Facility was a research facility owned and operated by the Umbrella Corporation. It was the last facility of Umbrella to be shut-down.

Overview
Located in Russia, the facility was disguised as an oil factory and used for research of B.O.W.'s. During some point in time, the T.A.L.O.S. was created here. During the events of Resident Evil: The Umbrella Chronicles, Jill Valentine, and Chris Redfield, and some Russian soldiers infiltrate the facility. As a result, Sergei Vladimir intentionally releases the T-Virus, and infects all the personnel in the facility. Jill and Chris eventually come face-to-face with the T.A.L.O.S., and despite its great strength, the B.O.W. is killed. Albert Wesker also infiltrates the facility to further his own goals. He eventually is attacked by 2 Tyrants, but his super-human abilities allow him to defeat both. He then meets Sergei, who injects himself with an unknown virus causing him to mutate. Wesker however, kills Sergei, and steals all data made by Umbrella, via the Red Queen. He then erases all data, and plans to bring Umbrella back. It is unknown what happened to the facility after the events, but it is shown that the Russian government is cleaning the facility of the T-Virus.
