The game uses a new 3D engine, which changes the gameplay and graphical look of the game, in comparison to 369 Interactive's CSI games.
This game, like the previous CSI games follows a distinct pattern of five cases, with the fifth case tying together the previous four.
A PlayStation 2 version of this game was released on the September 25 2007 in the United States. This version was made by Ubisoft's studio in Sofia, Bulgaria. The PlayStation 2 version is not the same as the PC version. The player has free movement and control of the view, which was required by Sony America. This change created extraordinary difficulties for the developer. Another difference with the PC version is the addition of a sixth case; which incidentally is from CSI: Hard Evidence. This is also the first CSI games to feature six cases.
