Narrator: A bizarre incident occurred in the outskirts of an American suburb called Raccoon City. It was later revealed that the terrible disaster had been caused by the T-Virus, a mutagenic toxin created by the international corporation Umbrella incorporated. The Raccoon police department special S.T.A.R.S Unit began an immediate investigation. The case was apparently closed thanks to the efforts of S.T.A.R.S members Chris Redfield and Jill Valentine. But the umbrella corporation’s experiments were far from finished.
