In France, Gillette (ops! I've just spoiled everything ;-) is online since about a month with Mission 5v1, an investigation game to recover an object whose code name is 5v1.
The hints to solve the crime are provided through a series of videos distributed via Dailymotion and on the Mission 5v1 site itself. Google Maps are also embedded in the site, as players are asked to spot the city where the object is kept hidden.
It looks like mystery is the common denominator to promote a razor online... last summer Gillette UK used the same inspiration to present the Fusion Power Stealth product range launching a "spy game" called The Undetectables. Unfortunately, in both cases, despite the good starting point and the good technical execution, the end result is not as engaging as it might have been.
