The group journeys through the newest Halo 3 maps. They get a grand tour with Guilty Spark's stunt double, Ralph, exploring the Foundry, Rat's Nest, and Standoff maps, and describing the capabilities of Forge. In Foundry, Simmons creates a mancannon for firing objects at Grif. Ralph explains the layout of Rat's Nest while discouraging Church from touching a twenty megaton warhead. The Reds are impressed by the base in Standoff, which Caboose claims to have created. Ralph concludes by announcing the release date for the maps.
