The campaign, invites consumers to guess the mystery flavour at www.doritos.co.uk/id3 for the chance to win a £20,000 reward.
The campaign is supported by a three-episode advergame, beginning on the 21st July and starring Football Factory's Tammer Hassan.
Consumers can take part in the online game where they can see themselves co-star along side Hassan.
The activity is being promoted alongside O2 and consumers with each limited edition pack will be given a code which gives them six lives to use on the adventure game.
Set in London's underworld, the player goes undercover to unlock the truth behind a case of mistaken identity.
Through Facebook Connect, the advergame pulls content from the player's Facebook profile and then dynamically inserts it into the film footage.
A live Twitter feed and Facebook fan page will keep Doritos fans up-to-date with the adventure.
The digital activity supports the integrated campaign led by Initials. Upset TV has created the online adventure, with rehabstudio responsible for the interactive production.
AMV BBDO has provided digital planning and consultancy.
