Recently, Bungie Studios community director Brian Jarrard - better known to Halo fans as "Sketch" - took some time to clear up a few lingering questions about Halo 3: Recon and Halo 3's upcoming Mythic Map Pack as well as some general Bungie topics.
From their informal chat, Joystiq learn that Halo 3: Recon will stay relatively true to Halo 3's formula, meaning that we won't be seeing any game engine improvements or added features. But Jarrard did confirm that (at minimum) one new weapon will make an appearance in Recon and a new soundtrack will debut. They also touch on the topic of Recon's Forge, learning what it is not and discuss why Bungie chose to not make it as feature-rich as a map editor like, say, what Far Cry 2 has to offer. There's Vidmaster achievement and Mythic Map Pack talk as well and the conversation somehow leads to the topic of global domination and pie.
