Ubisoft are bringing out two new titles based on the popular Crime Scene Investigates television series.

Fans of the behemoth Crime Scene Investigates (commonly known as CSI) franchise will get a double dose of murderous merriment this holiday season when Ubisoft release a new CSI title for both the Wii and the DS.

CSI: Fatal Conspiracy will be released on the Wii later this year and will see players tackle five brand new cases written by some of the writers from the show. The title will feature the likeliness of the season ten cast from CSI and is being developed by Telltale Games (Strong Bad's Cool Game for Attractive People, Tales of Monkey Island and others).

During the game players must gather evidence from the crime scene, look for vital clues and information that may help and interview witnesses and suspects. You will have all of the top of the range equipment on hand to help including ultrasound technology and a high-tech SLR camera.

Ubisoft will also bring out CSI: Unsolved! for the Nintendo DS before the end of the year. Once again there will be five new cases for players to get to the bottom of before it's too late. If you have a DSi or DSi XL you will be able to make use of the handheld's camera function in the laboratory or field work.
