Players can relive the beginning of the Resident Evil saga in a newly revamped "rebirth mode." Whereas the original game focused more on puzzle solving, this new version will place a heavy emphasis on action with more enemies and ammo as well as improved visuals for intense enemy confrontations. Also, nearly half the puzzles have been freshly upgraded providing new challenges for fans. In addition, the rebirth mode includes enhanced controls and will incorporate the DS system's unique feature set, utilizing the touch screen and microphone functions.
