Biohazard CODE: Veronica - Sega Dreamcast DC NTSC-J JAPAN Capcom Game

In December 1998, three months after escaping from Raccoon City (seen in Resident Evil 2) prior to its eventual destruction (seen in Resident Evil 3: Nemesis),[7] Claire Redfield raids an Umbrella Corporation facility in Paris in search of her brother, Chris Redfield. Discovered by Umbrella's security forces and eventually captured, Claire is imprisoned on Rockfort Island, a prison complex owned by the corporation, situated in the Southern Ocean. Sometime after her imprisonment, Claire finds herself released by the man who captured her, and discovers that an outbreak of the T-virus has occurred. In the resulting chaos, she finds herself teaming up with Steve Burnside, another inmate seeking to escape.

In their repeated efforts to explore the island and find the means to leave, the pair finds themselves confronting the island's commander, Alfred Ashford. Both Claire and Steve find him to be mentally unstable as a result of him switching between two personalities—his own, and that of his twin sister Alexia. Eventually, the pair manages to find a seaplane and use it to escape, only for Alfred to pursue them and switch their plane to autopilot, directing it towards another Umbrella facility in Antarctica. Upon their arrival, the pair finds that the facility had suffered an outbreak, and fight their way through the zombies and monsters within to seek a means of escape, battling with Alfred and fatally wounding him. Before he dies, Alfred frees his sister, Alexia, who had been in cryogenic sleep within the facility after injecting herself with the T-Veronica virus, an experimental virus that the Ashford family had developed 15 years ago. Awakened, Alexia manages to recapture Claire and Steve as they attempt to escape.
