For an additional, very strange, experience, go to Bungie’s E3 page, scroll down, and click on one of the Halo: Arms Race links. You’ll get what appears to be a live-action Halo test short, sort of a preparatory sketch for the (currently sidelined) Halo movie, which Microsoft apparently showed at E3. It gets very Delta Force-y toward the end — well, really toward the middle — but the first 10 seconds or so are gorgeous, especially the audio.
