Armchair detectives will have something to keep them busy this weekend, as a playable demo has just been released for CSI: 3 Dimensions of Murder.

The demo introduces the second of five cases from the full game released last month. This particular sequence should be of additional interest to adventure gamers, as the crime you'll be solving has taken place in a gaming convention that includes plenty of references to the cancellation of a highly-anticipated game.

3 Dimensions of Murder is the first CSI title with Telltale Games at the helm, and while it follows the format of the previous games quite closely, the new game offers longer and deeper cases, and brings the series into 3D for a more immersive gameplay experience.
