First there was the disaster at the mansion lab. Umbrella Corp designed the T-Virus, a muta-genic toxin for use in biological weapons. After breaking loose, living things mutated into all sorts of decaying creatures. The case was eventually closed, but Umbrella's experiments were far from over.

Now it's the worst possible nightmare: a new virus runs rampant. All of Raccoon City is infested. Blood-thirsty zombies, hideous mutations now overwhelm the community. When Leon and Claire arrive in town, their nightmare is just beginning...You now control their destiny.
