Play as a rookie investigator in CSI as you play to solve 5 murder cases in your work with the Las Vegas crime lab. Your co-workers are the characters from the CSI TV series, who are voiced by their same actors from the show. Difficulty levels affect how much help you receive in the game in the form of hints, hotspots, and info gained from evidence analysis. Unlike previous games from the series, this one provides a 3D world for you to move evidence objects in order to further inspect.
