Xbox.com
From Halopedia, the Halo wiki
Template:Ratings Xbox.com is the official Microsoft website for the Xbox and Xbox 360 consoles, as well as the online gaming service Xbox Live. It has pages detailing popular Xbox games, including each of the Halo games.
Of note is the backstory on the Halo: Combat Evolved page, which was the first official source to the events that led to the formation of the UNSC as well as human colonization. However, with the creation of the new Halo official site, the original Halo: Combat Evolved page has been taken down. The timeline is still hosted by Halo.bungie.org at their Halo Story Page.
The current Microsoft Silverlight-based page is essentially a web version of Halo Waypoint, serving as the hub for all the Halo games, Halo-related news and information.
On December 15, 2010, the Halo Waypoint forum at Halo.Xbox.com will have its forums merged with the Halowars.com forums, as the latter is scheduled to go offline. [1]
