You play the role of Torque, a death row inmate with an unclear past who has been imprisoned for killing his ex-wife and children. Shortly after being interred in a new prison on Carnate Island, an earthquake appears to release demonic creatures based on the many modes of execution used in the island's history. These creatures proceed to eliminate much of the prison population, leaving only you and a few other inmates and guards to fight against the horde and uncover what has happened.
The gameplay focuses on action-packed combat, as you navigate through the chaotic prison environments, fighting off hordes of demonic creatures. You will also have to solve puzzles to progress through the story and uncover the dark secrets behind Carnate Island's demonic outbreak.
