Microsoft is using Comic-Con to show off the first trailer for Halo: The Fall of Reach. It's a three-part CGI animated series that will be released for the launch of the Xbox One game Halo 5 Guardians on October 27.

The series is based on the first Halo prose novel by author Eric Nyland. Microsoft says:

"The animation is produced and directed by SEQUENCE, the award-winning Vancouver-based animation studio responsible for the Terminals featured in Halo 4 and Halo 2: Anniversary, and this marks their most ambitious and high-fidelity Halo animation yet."

"Halo: The Fall of Reach tells the dramatic tale of the origin and intrigue behind the SPARTAN program that propelled characters like the Master Chief and Dr. Catherine Halsey into the pantheon of Halo lore. The story reveals the events that brought Master Chief and Blue Team together, including their Spartan training and their daring mission to strike back at the Covenant during the first days of the deadly alien invasion."

The series will be available first for owners of the Digital Deluxe Edition, Limited Edition and Limited Collector's Edition of Halo 5: Guardians to watch on the Halo Channel apps. It's likely that Microsoft will collect all three parts and release it as a movie later on, as it has for its two live-action digital series Halo: Forward Unto Dawn and Halo: Nightfall.

Meanwhile, IGN has released the debut of the latest Halo 5 ViDoc, called A Hero Reborn. The 12-minute video shows members of the 343 Industries team talking about their goals for Halo 5, with a lot of talk about how this time it will feel more like a team-based experience in the campaign with the use of co-op and AI characters.
