Months ago, right when the game started, a riot occurred at multiple prisons in the city. Without electricity and guns, the guards of the prison were unable to hold the prisoners back, which led to many of them dying in the process.
The Butcher, Amanda Rainford was one of the prisoners that escaped. Upon escaping, she found herself wandering the streets of the city.
She didn't know anybody here, and thanks to the fact she was wearing a prison uniform, she, as well as all the other prisoners, were quickly chased out of the city by the combined efforts of the police and the residents of the city.
Amanda and the other prisoners soon found themselves in the forest, a place they soon realized was many times more dangerous than the prison. Some prisoners panicked at the sight of the monsters, some started slaughtering monsters and prisoners alike, and there were others started leading their own groups.
