Halo is one of the biggest video game franchises on the planet. It has fans, lots of them: dedicated, hardcore, sci-fi fans.

Working with 343 studio – the games creators and Twofifteenmccann San Francisco – our mobile campaign became the digital arm of the global campaign ‘Hunt the Truth’.

Unlike other Halo games, Guardians had no clear hero and no clear villain. We created #huntthesignal, an Alternate Reality Game, that turned fan’s smartphones into a different kind of Spartan weapon.

Players were invited to solve puzzles located across a variety of digital and real world locations. The team that discovered the clues fastest, would find themselves immortalised in the next Halo game.
