Ripper is a Full-motion video game that has a cast that includes celebrities such as Christopher Walken, Scott Cohen, Tahnee Welch, Burgess Meredith, Karen Allen, David Patrick Kelly, John Rhys-Davies, Jimmie Walker, Anna Levine and Paul Giamatti. Ripper takes place in New York City in the year 2040. It opens with the investigation of the recent murder of Renee Stein, the third victim of a serial killer known as "The Ripper", largely out of the modus operandi similarity to Jack the Ripper. The player assumes the role of Jake Quinlan, a reporter for the Virtual Herald, whom The Ripper sends messages to detailing his murders (an act attributed to Jack the Ripper, although no letters have been proven to come from him), who along with the police, namely Detective Vincent Magnotta, is seeking The Ripper's true identity.
