And who better to show us around the new maps than the crew from Red vs Blue?

Bungie has an FAQ about the new maps downloads here. Additonally, they have some notes about a play list update (which isn’t yet live as of this writing) and more right here.

PoweTip: Download the maps from Marketplace so you can do background downloading instead of waiting at the screen. Better to kill time in an XBLA game or watching a video than staring at a progress bar.
