A man lies in a darkened cell, consumed by pain and sickness. He does not know where he is. He does not know how he came to be there. He does not even know his own name. All he knows is that he is being tortured by a bizarre, bespectacled man, who addresses him only as a number - Twelve-Thirteen.

Every day, Twelve-Thirteen is taken out of his cell and goaded into running a dangerous hazard course, apparently for the sole amusement of the bespectacled man. Today seems to be no different. But while Twelve-Thirteen sits brooding in his darkened prison, the door suddenly falls open with no apparent cause. To discover the answers to all of his questions, Twelve-Thirteen must adventure into the unknown world beyond the cell...

It plays as an adventure game with a light mix of action thrown in. The health system is an interesting take on a typically HP-saturated market: as you take damage, the beating heart in the corner pumps faster, threatening death, and adding to the atmosphere. With a gripping storyline that far exceeds its meager graphical offerings, you'll find yourself entirely immersed in a game that alternates between terror, confusion, and an overarching ending that will haunt you.
