The plot revolves around the kind of conspiracy that Chris Redfield and Jill Valentine regularly find themselves involved in with the Resident Evil games, with mad scientists, spooky mansions and of course hordes of shambling zombies. It is the first in a successful series which mixed the undead slaying of Resident Evil with the intense blasting of classics like Operation Wolf, and which brought the on-rails shooter to a whole new level. While this adaptation of Sega's classic arcade light gun-based shooter may lack the sheer visceral thrills of gunning down endless swathes of mindless zombies with a plastic piece of heavy duty weaponry, it remains an immensely enjoyable slice of action gaming.
