Gamasutra is proud to present a series of weekly podcasts will alternate between two sources under the overarching GDC Radio brand - the Gamasutra podcast, a new original podcast show, and GDC Radio Archives, which will feature exclusively the best lectures, tutorials, and roundtables from this and previous years' Game Developers Conference. Today's GDC Radio lecture comes from our extensive archive of Game Developers Conference recordings. In this panel from GDC 2003, Bungie's Jaime Griesemer and Mat Noguchi, along with Microsoft's Marty O'Donnell, discuss the iterative, creative process that went into the making of both Halo and Halo 2, from design, engineering and audio perspectives. You can now read more information on the podcast and click through to download this week's installment (no registration required, please feel free to link to this feature from external websites). You can subscribe to GDCRadio.net podcasts using iTunes and searching the directory for GDC Radio or by clicking this link.
