L.A. Noire is set in Los Angeles in 1947 and challenges the player, controlling a Los Angeles Police Department (LAPD) officer, to solve a range of cases across five divisions. Players must investigate crime scenes for clues, follow up leads, and interrogate suspects, and the player's success at these activities will impact how much of each case's story is revealed. The game draws heavily from both the plot and aesthetic elements of film noir, stylistic films made popular in the 1940s and 1950s that share similar visual styles and themes, including crime and moral ambiguity.
