CSI: Deadly Intent puts players in the role of a Las Vegas crime scene investigator, alongside series regulars such as Ray Langston and Riley Adams. A touch-screen point-and-click interface makes exploration and interaction straightforward, allowing gamers to focus on using intuition and deductive reasoning to solve the mysteries. As in earlier games based on the long-running television crime drama, the interactive adventure has players proceeding through a sometimes-gruesome story by interviewing witnesses and suspects, searching for clues, and analyzing evidence back at the lab, with the help of the CSI team. Exclusive to DS, the Hidden Files edition of CSI: Deadly Intent features multiple cases which seem unrelated at first, but which begin to reveal a sinister conspiracy further investigation. The game's graphical style mimics detailed, hand-drawn animation, for a clear and informative view of the small-screen crime scenes. ~ T.J. Deci, All Game Guide
