As the title suggests, the game draws heavily from both plot and aesthetic elements of film noir – stylistic films from the 1940s and 1950s that shared similar visual styles and themes including crime, sex and moral ambiguity and were often shot in black and white with harsh, low-key lighting. The game uses a distinctive colouring-style in homage to the visual style of film noir. The post-war setting is the backdrop for plot elements that reference the detective films of the ’40s.
