Halo 3 Beta/Errors
From Halopedia, the Halo wiki
List is a list of Halo 3 Beta Errors and fixes, if any.
Release Delay
The Halo 3 Beta was announced by Bungie and Microsoft to be released at 5:00 AM PDT (8:00 AM EST) for owners of specially-marked copies of Crackdown. However, many players reported to Microsoft that under the "Downloads" section of Crackdown, the option to download the Halo 3 Beta was "grayed out" and unavailable. Bungie found the same problem and relayed the information to Microsoft, who promptly posted that consumers had problems downloading the Halo 3 Beta from Crackdown. At 4:00 PM PDT (7:00 PM EST), 11 hours after the Halo 3 Beta was supposed to be released, Microsoft announced that they had determined the problem and were creating a fix that would be "most likely in the form of a title update", and that a workaround was expected to be released in 3 to 6 hours.
2 hours later, Microsoft updated its announcement, saying that a fix had been found, and that it was undergoing final testing to ensure its accuracy. An hour later, at (10:00 PM EST) Bungie and Microsoft both proclaimed that a fix had been released. Beta players would have to restart their Xbox 360 consoles, and insert the Crackdown CD-ROM, when they would get a prompt to download an update to Crackdown that would allow the players to access the Halo 3 Beta.
Due to the bug and the subsequent massive public disapproval, Bungie decided that the Beta would be pushed back from the Beta ending date of June 6th, 2007 at 11:59PM PDT to June 10th, 2007 at 11:59PM PDT, allowing gamers to have four more days with the Beta, compensating for the one day lost in trying to download it from the Crackdown menu.
