The crew over at Microsoft sent along the direct feed footage of Halo 3: ODST from their E3 2009 Keynote. Chances are you followed along with Joe Staten on the 1st of June, but if you want to relive the event in 720p, head into the
Multimedia section of our Halo 3: ODST Project Page to reminisce. 720p version is linked just to the right of the thumbnail.
