Game information
Dark pathways, inhumane torture chambers; frozen, eternal museums of suffering. Inside each enigmatic maze, agent Thomas Foster follows the trail of scattered victims leading him to the next madman. In that very same paths, he relive their torments in his own flesh and bone, allowing the pain in every scream to reach his senses, dragging him, bit by bit, into a vortex of utter insanity. But he knows this, alas, this is the toll of a telepath. And maybe, that toll would be too high for him to bear.
