As announced last week, today sees the launch of Sony Mobile's "Xperia Unleashed" promotion, which challenges Xperia fans in the UK to track down tiny robots in order to win Sony swag. The story goes something like this -- the tiny Xperiabots seen in this ad have escaped, and instead of devouring the world at a microscopic level until all that remains is a a fine grey powder, the 'bots have chosen to hide out in Manchester and London with QR codes on their backs. These codes can be redeemed for an assortment of prizes, including Xperia NXT phones, Sony TVs and tickets to DJ sessions, movie premieres and gigs.
Fortunately you won't need to search the length and breadth of the country, as Sony's helping fans out by pinpointing certain Xperiabots on a Google Map. The manufacturer also promises further hints across its social networking channels as the month progresses.
