Originally we indicated that this week was our target for updating the Halo 2 Xbox Live matchmaking playlists and resetting all player rankings. We are holding this update while we investigate and fix some of the Xbox Live download problems that people have been reporting. The good news is that almost everyone who initially had issues downloading the maps should now be able to do so. However, there may be some people who are still unable to download the maps for a variety of reasons and we’re working with the Xbox Live team to narrow down the potential cause and implement the solution.
This playlist update and rank reset will probably occur next week, pending the outcome of our ongoing work with the Xbox Live team. In the meantime, you are of course able to enjoy both Tombstone and Desolation in online custom games and offline Splitscreen/System Link play. Please stay tuned to Bungie.net for the latest info. Apologies for the inconvenience.
