Resident Evil: Survivor 2 “Code: Veronica” ('Gun Survivor 2: Biohazard Code: Verionica' in Japan) is a light gun game by Capcom developed in conjunction with Namco exclusive to PAL regions and Japan. The game features characters and stages taken directly from Resident Evil Code: Veronica, although the game has no bearing on the Resident Evil plot. The game also features the return of the Nemesis, who appears on the map to chase the player if time is running out, serving as an arcade mechanism to prevent players from staying on the machine too long. Claire Redfield is continuing to look for her brother after the Raccoon City incident and she was tipped by an unknown source about an Umbrella facility in Paris. When she tried to infiltrate the facility, she was caught, after which she was taken to the Umbrella prison in Rockfort Island. She meets up with another prisoner, Steve Burnside, and plans to escape while an outbreak of the T-virus is released onto the island.
