"Yo dawg, I herd you like updates, so here's an update about your Title Update!"

During the wee hours of the morning on September 21st, we rolled out a Title Update for Halo: Reach. Over the course of the day, both retail disc owners and Games on Demand users were prompted to download it. The Halo: Reach “Preview Disc” (a small amount of these discs were given to certain community members and it has nothing to do with either Games on Demand versions or normal retail discs) cannot be updated with a conventional TU, though. We understand this is a frustrating situation for the affected users, and we are actively investigating different options. Please know we consider this to be extremely important, and we will provide an update when we have any news.
