Caucasus outbreak

The Caucasus Outbreak occured at some point in 2003 at the Umbrella Caucasus Research Facility in Russia. One of the final Umbrella-specific outbreaks, this event set a chain of events in motion which led to the shut-down and dissolultion of [[Umbrella Pharmaceuticals Inc.]

History
During the events of the Raccoon City Outbreak in 1998, Umbrella officer Sergei Vladimir moved certain special projects from the Spencer Estate to the Caucasus facility - namely, the T-A.L.O.S. project and the Red Queen computer. After the destruction of Raccoon City, Vladimir was named head officer of Umbrella by Ozwell Spencer, who went into hiding soon after.

Outbreak
Sometime in 2003, Albert Wesker leaked information to the fledgling organization BSAA about the location of the T-A.L.O.S. project. Having discovered the location of Sergei Vladimir, he intentionally released the t-virus into the Caucasus facility, infecting 98% of the research staff and releasing many of the B.O.W. experiments. As Wesker infiltrated the facility, a Special Ops squad led by Chris Redfield and Jill Valentine invaded the facility from the other end.

Wesker was confronted by Sergei after making his way down the main cable car shaft; Sergei commanded his twin Ivans to attack as he made his escape. Wesker managed to defeat the Ivans, and confronted Sergei at about the same time as Jill and Chris reached the T-A.L.O.S. project. In two simultaneous battles, Wesker defeats Sergei after Sergei injects the virus into himself and mutates, while Chris and Jill manage to destroy T-A.L.O.S. (Curiously, Sergei offers commentary during the T-A.L.O.S. battle, despite being busy battling Wesker). After, Wesker managed to copy the entirety of Umbrella's computer information onto a single disc, and wipes the Red Queen's memory.

Consequences
Shortly after the Caucasus outbreak, Wesker leaked the contents of Umbrella's unsavory research and business dealings, while anonymously testifying against Ozwell Spencer. With Umbrella out of the way, Wesker sets his sights on the acquisition of Las Plagas, to take place in the following year. Meanwhile, Jill and Chris officially form the BSAA and remain partners until the events of Lost in Nightmares.
