The Hive (Resident Evil)

The Hive is a top-secret underground facilty located deep (approx 1/2 a mile) under the streets of Racoon City and is home to more than 500 Scientists, Technicians and support staff employed by the Umbrella Corporation. Umbrellas most sensetive and controversial work is carried out at the hive and is supposedly the location where the T-Virus was first created, and this is implied in the film Resident Evil.

After engineering the T-Virus, Dr. Charles Ashford was instructed to oversee the design and construction of the Hive and was then placed with all Hive related responsibilities, because of this he produced the 'Red Queen' a highly intelligent computer system which controls the entire Hive. In the film, a holographic representation of the 'Red Queen' is referred to as being moddeled on Charles Ashford's daughter, Angella Ashford.

During the attempted theft of the T-Virus from the Hive, a vial was broken, releasing the T-Virus into the Hive's ventillation system. Shortly after, an uncontrollable pattern of infection began to spread and the 'Red Queen' sealed the hive and killed everybody inside in an attempt to contain the infection.

Shortly after, Umbrella dispatched a team (UBCS??) to invesitage the goings on at the Hive and shutdown the Red Queen. After successfully shutting down the Red Queen and the power to the Hive, The hive staff killed by the Red Queen are reanimated by the T-Virus and, due to there being no power to keep internal doors locked, are soon roaming arounf the Hive. None of the team sent by Umbrella survive, however, the head of security at the Hive, Alice, manages to escape, only to be seized by Umbrella scientists
