343 Industries faced many challenges when they took on the 10-year-old Halo universe, and all the fan expectations that accompanied that universe. One of the most daunting tasks was determining how to introduce such an established fiction to potential brand-new fans, while simultaneously rewarding those who have played every game and read every book in the sizable, extended Halo fiction collection. Responding to fan appreciation of previous live-action marketing campaigns, Halo 4: Forward Unto Dawn was born. In this talk, 343 Industries will do a postmortem of the creation of the groundbreaking web series, and what lessons were learned. The talk will cover everything from developing partnerships in Hollywood, adapting game content for different media, and how to coordinate fiction between the very different schedules of movies and game creation.
