Fans of the hit CBS television show can now become active participants in the search for evidence along with the cast of CSI: Crime Scene Investigation. Players assume the role of a lowly CSI intern as they prepare to solve five cases by visiting the crime scenes, collecting evidence using 14 forensic tools, having it analyzed, and interviewing potential suspects with the help of Las Vegas Police Detective Jim Brass. The goal for each case is to gather enough evidence to lead to an arrest, at which point another case will become available. After a mystery is solved, players will receive feedback from Gil Grissom on their performance and will be assigned an overall rating based on the total amount of information collected.
