William Birkin, the genius responsible for the creation of the G-Virus, was once the research director of the Umbrella Corporation until agents were sent to steal his research. Severely injured and facing death, the brilliant scientist was forced to inject himself with his own virus to seek revenge. Now, he roams the ruins of Raccoon City as a horrifically mutated monster, an almost unstoppable foe.

Can you defeat William Birkin while trying to escape the nightmare?
