My good friend David, who works as a pathologist, called me that night. He was very excited and scared. A human body had just been brought to the morgue but he said that it was an unusual corpse. He recommended that I come as soon as possible if I wanted to be the first to receive materials for an article that could become a real sensation. After 20 minutes I was already in the morgue and what I saw shocked me. Returning home with the materials, I became a hostage in my own house, with a terrible creature prowling the corridors. The only salvation is a bright flash on the camera, which scares away the creature. I need to deal with all the closed doors and solve these damn riddles... No way in hell I'm gonna die. I must get out at any cost.
