This game is brilliant. You play a rookie CSI in 5 cases, each case pairing you up with familiar faces of the CSI cast. In case 1 you're paired with Catherine, and in the other four you're paired up with Warrick, Sara, Nick and Grissom, respectively. What's awesome is they're all voiced by the original actors, so it's like you're actually playing a part of the show itself. The graphics are really good. There's a lot of detail and also a lot of places to explore. The music is brilliant, all of the clips taken from episodes of CSI.
As well as the five CSI's, you can also work with Al Robbins, Greg and Jim Brass. You can examine bodies in the morgue or ask Al questions relating to time of death etc, while Greg analyses evidence you pick up and scans them into either the computer or the microscope so that you can look at the evidence more thoroughly. You can get warrants or interrogations from Jim Brass. He can also look up bank records, etc.
It's a very immersive game. The graphics, the music, the characters and the twisting storylines make for a very addictive and unique game-playing experience.
