Now you lives an isolated life with your German Shepherd Samantha (Sam) in a heavily fortified building in Washington Square Park you experimenting on infected rats to find a cure for the virus, and waiting each day for any survivors who might respond to your continuous recorded radio broadcasts, which instruct them to meet you at midday at the South Street Seaport. to cope with your loneliness, you regularly "talks" to some mannequins and the characters on film recordings from video stores, searching for food and supplies. At night, you barricades yourself with Sam inside your base.
