This is all of the Resident Evil games we currently have - 

The plot lines of the main installments up to the third game all concern the T-Virus outbreak in the Arklay Mountains and its spreading to nearby Raccoon City.

1996's Resident Evil for the PlayStation follows protagonists Chris Redfield and Jill Valentine, who become trapped in a mansion in the mountains, trying to search for the survivors of the Bravo team of the special police unit S.T.A.R.S. They discover that the mansion conceals the Umbrella Corporation's base where they developed the T-Virus with their end-goal being the creation of a bio-weapon known as the Tyrant (for whom the virus named). Playing as either of the characters, the player must navigate the mansion alternately with the help of Barry Burton or Rebecca Chambers until they are betrayed by Albert Wesker who was secretly planning to steal the T-Virus. Though appearing to be killed by the Tyrant, Wesker survived and masterminded some later events behind the scenes.
