Resident Evil Code: Veronica X begins as Claire Redfield leaves Raccoon City for Europe, headquarters of the Umbrella Corporation, in search of her brother Chris and to solve the mystery surrounding Umbrella Corporation's secretive activities. In her search she is captured and sent to an isolated prison on a desolate Island. While it remains unexplained how Chris, 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 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 assume the role of Chris Redfield in their efforts to stop Umbrella's devious plans. One of the many features that make Code Veronica different from previous Resident Evil games is the Real World System (RWS). 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.
Resident Evil Code: Veronica X contains never-before-seen footage that focuses on battles between Chris and the enigmatic character, Wesker, and sheds new insight into the ominous Resident Evil story line. Flesh-eating zombies, horrific beasts and even stranger mutations have spread on a global scale! Just how far does this twisted conspiracy extend? What is Umbrella Corporation really up to? And who is behind this bio-tech terror? To her horror, Claire discovers Umbrella Corporation's insidious activities are not isolated to the remote, mid-western city. No. Something much larger is going on here.
