Halo 3:ODST Mythic Map Disk Preview

In September the world of Halo creeps back into out lives with Halo3:ODST. Today being Bungie Day, the 7th day of the 7th month they have released a sneak preview of 3 of the maps from the Mythic map Disk that comes with ODST. I still need more convincing to pay the full 59.95 retail price for what seems to be an expansion. September is still almost 3 months away so who knows.
