MacLaren McCann (Canada) recently created a pretty cool ARG campaign for the launch of Halo 3 ODST by developing a seamless online / offline experience for fans that included a guerrilla style scavenger hunt with viral videos, hidden clues, encrypted messages, GPS coordinates, custom Google maps, real world locations, interactions and sms communication.
If you could crack the clues, you’d get a VIP ticket to the launch party! The campaign built a fair bit of hype online in Canada and the video above is a quick case study showing the results. A great example of how an interactive experience can be brought offline with great effect. (Thanks Andre)
