In Gun Survivor 2 Biohazard Code: Veronica on Playstation 2, If you collect all the gems throughout the game and defeat the Tyrant, you'll be able to face Nemesis in battle. Mind you Claire has never encountered the Nemesis in the main games. This story portrayed is non-canon; it is a dream Claire Redfield has during her trip to Antarctica in the main Code: Veronica game.
