"Love free stuff? Then check out The Suffering, a survival horror shooter from 2004. In it, you play as an inmate named Torque held at a maximum security prison. Turns out, there were some gruesome experiments and executions held there, fueling the dark forces that are taking over now. Did we also mention that you can transform into a giant, rampaging monster? This game has it all, and it's available now - complete and totally free to play."
