Based on the highly popular Sega Dreamcast version, Resident Evil Code: Veronica X takes place in an isolated prison on a desolate island with Claire Redfield in search of her brother, Chris. While it remains a mystery howChris, one of the original S.T.A.R.S. team members, appears in Resident Evil Code: Veronica X, players will be reacquainted with his iron will, body of steel and munitions expertise to seek the truth behind the dreaded Umbrella biotoxins. In Resident Evil Code: Veronica X, players control Claire at the beginning of the game and later can control Chris Redfield. One of the many features that make Code: Veronica different from previous Resident Evil games is the Real World System (R.W.S.). Now when Claire opens doors, solves puzzles, stores items or ammunition, they remain in the same spot when playing the second half of the game as Chris for added realism and increased character interaction.
