There has been an outbreak of the virus in Raccoon City. The screams of survivors, infected people and dogs can be heard in the streets. You have good physical strength and training, so it wasn't too hard for you. When you were exploring one of the buildings to find shelter for the night, a zombie grabbed you from behind. Trying to get out, you couldn't. The infected one is about to bite you, and then it's over. You've been knocked to the floor, but you're still trying to get out. Then you hear a shot, and the infected person begins to weaken. You push the zombies away and step aside yourself. The guy kills the zombies and comes up to you. "Is everything okay? Have you been bitten?" He asked, clearly worried.
