Games about maniacs
Games about maniacs usually tell a short story in the setting of our time, where the player either gets into the skin of a serial killer himself, or becomes a defenseless victim who must survive in endless deadly chases. Sometimes a maniac has supernatural powers that make him practically invincible.
Some games about maniacs and murderers are based on multiplayer, an excellent example is Dead by Daylight, which is not the only one of its kind (it is just more famous).
