Player will begin his journey as tormented soul, without any memories about his past.  Ability to control people on his path, and even simple minded demons, gives player the necessary measures to survive in those extreme conditions. By exploring hostile environment, and talking with the weary men, hero will soon understand that there is only one way to escape from Hell, and it will require a meeting of the mystical Red Goddess, who rules this segment of hell.

Player have ability to choose from three different forms, which will completely change gameplay experiences. From weak human to almost immortal, powerful demon? Why not!

• Ethereal soul: Playing in this form, makes player temporary immortal, and give him ability to take control of people and demons. He can levitate and become invisible for enemies.
• Martyr: Taking control of the humans, will be main part of the game. In this form, players need to be careful, and move in silence. Martyr  can use torch, swim under water, holding his breath, resolving puzzles and even making traps. He also have ability to discover secret chambers, finding hidden painting and collectibles, and he have special stealth movement. Martyr is the weakest body that player can control, so he is forced to hide from powerful demons and he must be careful at every step
• Demon: Controlling this strong, almost immortal creature is hard, but gives many abilities needed to make progress. Demon can collect hearts, and this gives him one chance to overcome death. As an example, player can fall from an huge mountain and hit the ground. But if he have at least one heart collected, he can survive this. Demon is very fast and aggressive creature, which can use telekinesis and his own hands, to kill anyone on its path.

Also, player can upgrade his abilities in three main parameters:

• Sound - reduce sound that player makes as a Martyr,
• Breath - increase among of time that player can play without making a breath (useful for swimming and hiding),
• Defence - give an option to survive attacks from weaker demons.
