Yesterday Microsoft held an event called X10 in San Francisco, during which the publisher shared a lot of details about several high-profile upcoming games like Halo: Reach, Alan Wake, Fable III and many more. Our intrepid Owen Johnson was on the scene and will be bringing you coverage of the event later in the day.

One piece of media released during X10 was this lengthy Halo: Reach video documentary, which I recommend watching even if you're not one of Halo's devoted fans. Not only does it demonstrate that Halo: Reach looks like a major evolution in the Halo franchise, it's also a fascinating look into big-budget game development.
