Not much has been said yet, only little has been shown about it as well. It's set in the late 1940's in a perfectly re-created Los Angeles (That we'll see about). It's an open world game, giving the player the task of solving a bunch of murders in the city. The game is also said to have the best motion expressions on the characters we've ever seen. Other than that you'll play as Cole Phelps voiced by Aaron Staton, and so far the game has over 20 hours of voice acting.
