The Suffering is the first game of its kind to probe into the very unsettling and seedy underbelly of a maximum-security penitentiary haunted by horrific and grotesque apparitions, represented by the unique and disturbing executions that previously befell them. Gamers take on the role of Torque, an inmate who must face much more than his own inner demons and the harsh and gritty reality of death row, as he fights to escape the unleashing of the penitentiary's gruesome secrets in a challenge more terrifying than fighting death itself. The Suffering features ultra-mature content and three distinctly different endings depending upon how you choose to survive.
