The third in the Halo Wars "Universe Expanded" videos is now available on Xbox Live Marketplace (for Gold members). Again we see several voices in the gaming industry waxing poetic about Halo. The latest video focuses on exactly how Halo Wars adds to the lore established in other Halo titles. On particularly interesting tidbit, Microsoft's own Frank O'Connor notes that the new elements present in Halo Wars will show up in future titles in the franchise. Who knows, maybe we'll be hijacking Locust tanks or piloting a Vulture in Halo 3: ODST.
