Iris is a notable alternate reality game (ARG) and viral marketing campaign for the upcoming Halo 3 video game being produced by Bungie Studios. It is similar to another alternate reality game as marketing, the I Love Bees "ARG" from Bungie's Halo 2. Like I Love Bees, Iris is an ARG involving thousands of players around the world and is notable for its official sponsorship by Bungie, as well as its link to Halo 3. Detailed recording and analysis of events, messages, and everything else can be found at the popular ARG sites args.bungie.org, halo.wikibruce.com, Unfiction.com, Hushedcasket.com, and a group on the Bungie.net forums titled "CompoundIntelligence".
