GameSpot
Review, by Giancarlo Varanini: "those who have stuck with the Resident Evil series despite its dogged insistence on not changing its ways will find that Resident Evil 0 still has a lot to offer in the form of some terrific graphics, a couple of small changes to the series' gameplay, and a story that unveils the origins behind the Umbrella corporation."
