This demo is for the PC, but the cases are the same in all three versions, so it should give you a good sense of the game no matter which platform you're considering.

Developed by Telltale Games, CSI: Hard Evidence will continue the crime-solving experience of Ubisoft’s CSI video game series. Players will join Gil Grissom, Catherine Willows and the rest of the Las Vegas cast to help solve crimes using realistic techniques and lab equipment. CSI: Hard Evidence features forensic reconstructions and atmospheric crime scenes taken directly from the television show, including an all-new garage lab for analyzing large evidence such as cars and boats, improved evidence gathering, review and lab mini-games, and more areas to explore, resulting in longer play experiences.
