Baltimore, Maryland is a location featured in Season 3 of Telltale's The Walking Dead. It is the hometown of the García family, where Javier, Gabe, Kate, and Mariana stayed for three months after the global outbreak.
Pre-Apocalypse
The Garcia family lived in Baltimore before the global outbreak, where Javier played professional baseball before being thrown out of the league for a betting scandal. The family lived in a large suburban residential area somewhere outside the city.
Post-Apocalypse
Like many other cities across the United States, Baltimore was gripped by a wave of fear and chaos during the onset of the global outbreak. When trying to return home to see his father before he died, Javier was forced to abandon his car on the highway after encountering a gridlock. After their father died, reanimated, and bit their mother, Javier's brother David tried unsuccessfully to take her to the local hospital, but was forced to flee the city after she died en-route.
The rest of the Garcia family, including Javier, Kate, Gabe, and Mariana, barricaded their family home and remained in Baltimore for three months, waiting for David to return. During that time, Baltimore presumably fell to the undead and was abandoned. Eventually the Garcias packed up and fled the city, leaving behind a note in case David returned to the house.
