A recent ESRB rating has unveiled a new title for the DS based on the film Shutter Island.

While a PC game based on Shutter Island has already been released it seems that City Interactive is working on a DS version according to a recently unveiled ESRB rating.

In the rating the game is described as seek-and-find puzzle game based on the movie in which players take on the role of U.S. marshals investigating Ashercliffe Hospital for the Criminally Insane. Players must search for clues, look over patient's files and interview hospital personnel.

The game is targeted to the adult audience judging from the murders that are featured: the drowning of a patient's three children; the arrangement of dead bodies around a dinner table; and the scalping of relatives for use as hats. Expect more news soon when the title is officially announced.
