You play the role of Torque, a death row inmate with an ambiguous past who has been imprisoned for slaying 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 sordid history of the island. These creatures proceed to eliminate much of the prison population, leaving only you and a few other inmates and guards to survive.
The gameplay follows Torque as he navigates through the crumbling prison, fighting against hordes of demonic enemies inspired by various execution methods. You'll have to use stealth and strategy to outsmart the creatures, find supplies and upgrades, and uncover the mysteries behind the island's dark past.
