A corporation called Umbrella developes a virus that turns ordinary people into zombies, multiple biological weapons such as Nemesis, T-90, Tyrant are also developed to crush the ones that dare to oppose them, a special trained group of officers are sent to Racoon City to save the survivors...

The description matches Resident Evil perfectly - Umbrella Corporation creates the T-virus that turns people into zombies, develops biological weapons like Nemesis and Tyrant, and the story is set in Raccoon City where special forces teams (like S.T.A.R.S.) are deployed to save survivors. Silent Hill, Alone in the Dark, and The Darkness are entirely different game franchises with unrelated plots.
