(Covers information from the S.D. Perry novels)
The G-Virus was developed by Dr. William Birkin and his wife, Annette, within a secret laboratory complex under Raccoon City. The project had been going on for some time prior to 1998 to create a new viral weapon to supplant the T-Virus. Following the Spencer Estate explosion, relations soured between Umbrella's executives and the Birkins, who suspected they would force an end to research to recover costs.
