Noir Syndrome is a procedurally generated Detective Murder-Mystery with a new story every time! Featuring slick pixel art animations and a jazzy soundtrack, the player is thrown right in to a highly stylized vision of film noir. Visit locations, interrogate suspects, search for clues, and eventually solve the case before the killer escapes – or you wind up dead yourself.
