We can confirm the team is working on new downloadable content for Perfect Dark Zero, including new multiplayer maps, which we anticipate will be available in the very near future.
However, the mail to Xbox Live members was sent prematurely, and we apologize for the confusion. Please check back soon for this exciting new content.
seems like they release all their stuff early, first the vista requirements, then the 360 dashboard update info, now this? hopefully the maps will be like the halo2 map pack where they start as a pay thing and turn free after X months pass
