Description: "Murder Detective Jack the Ripper" is a full-voice adventure game set in a fictional London with advanced medical technology. Private detective Arthur Hewitt recognizes the existence of "another person" in himself, perhaps from the shock of discovering a corpse while investigating a serial murder case. In a strange communal life with the illusion of Jack the Ripper, Arthur gets caught up in a big incident involving all over London. It branches to "Detective Route" and "Murderer Route" depending on the choices the player follows. Is it a "detective" who thinks intelligently and exposes the crimes of criminals? Is it a "murderer" who moves impulsively and judges criminals with his own hands? The choice of the player has a great influence on the ending of the story, such as the solution of the case and the life and death of the character.
