The Umbrella Corporation is a fictional bioengineering pharmaceutical company in the Resident Evil universe. At the beginning of the 21st century, the Umbrella Corporation had become the largest commercial entity in the United States. Nine out of every ten homes contain its products. Its political and financial influence is felt everywhere. In public, it is the world’s leading supplier of computer technology, medical products, and healthcare. Unknown, even to its own employees, its massive profits are generated by military technology, genetic experimentation and viral weaponry. The Umbrella Corporation is most infamous for being largely responsible for the infection that sweeps across Racoon City (and other areas of the world) due to the creation of several highly volatile mutagenic viruses and parasites – the most famous being the G-Virus, T-Virus and Nemesis Parasite.

The Arklay Laboratory was the first of many clandestine biological weapon research laboratories to be established by the Umbrella Corporation which operated as an annexed laboratory of Umbrella U.S.A. The actual facility was hidden beneath a large European-style mansion estate built in the backwoods of Raccoon Forest in the Arklay Mountains on the outskirts of Raccoon City. In the May of 1998, the experimental t-Virus was intentionally leaked throughout the grounds and the nearby training facility by Dr. Marcus in revenge of his apparent assassination some ten years earlier. The virus leaked into the water supply, spreading the virus to the majority of the staff. Over a period of a month, the remaining staff would make attempts to stop the spread of the virus and its effect on humans – zombies – and the release of experimental B.O.W.s in the panic. Anyone suspected of being a carrier would be killed by their colleagues, unaware that not only they, but everyone was already infected. Isolated survivors would commit suicide in a last-ditch attempt to avoid becoming food, along with the terrifying thought of becoming one of them.
