Bungie reports that Volume 2 of the Halo 2 Soundtrack has been mastered, so it should be available to purchase soon. They also have their E3 report up, and the lowdown on the latest Halo Humpday Challenge.
HBO have announced that they have opened their new Halo Cutscene Library. It only has the opening Pillar of Autumn cutscene so far, but hopefully it won’t be long before the full set of cutscenes are available for download.
The Halo Story Page has been updated by Jillybean. Mostly speculation regarding Forerunners/The Ark/Humans.
