Build your engine of powerful relics and uncover secrets of an ancient castle in order to defeat supernatural monsters and steal their body parts... to make a new, super-human body of your own.

You are a tormented spirt with the ambition to build yourself a new body, by killing vampires, werewolves and zombies and grafting together their power-granting limbs and organs to build yourself a new body. You’ll haunt the castle grounds during the day, collecting energy and relics, and enter the castle to fight monsters at night. But beware! The castle changes every night and you might encounter obstacles, or even traps set by the monsters! The phase of the moon might also determine your fate, by granting you... or the monsters, more power.
