Bungie has been speaking briefly about Halo 3 in the first of a number of planned podcasts from the studio.
Major revelations on the FPS sequel remain tightly locked in the Bungie vault, but topics discussed include achievements in Master Chief's hotly anticipated return to battle, and we're teased with a "Halo 3 Mystery Sounds" section - in a nuthshell, lugholes are assaulted by one of the game's new sound effects.
In addition, Bungie takes time out to talk about Halo 2 on Windows Vista in its podcast, which is says is "coming along great" and introduces us to the, ah, Bungie jingle.
Plus, the dev's accompanied the launch of its podcast with a reveal on the official Halo 3 logo, which you can see for yourself on this here page. Who'd have thought it would have looked like that, eh?
