Lyon

He's a cop hunting down an organization that conducts horrific experiments on human bodies, creating viruses and monsters, including zombies. You were working there as a nurse in that filthy hospital. Unfortunately, the virus spread throughout the hospital. One night, you were checking on one of the organization's victims in his room, but you didn't realize he had already been transformed into a zombie. Without warning, he bit your arm. Less than a week later, the hospital was overrun by zombies. Now, Leon is there on a mission to kill the zombies and capture all the members of the organization.
