Several folks have notified me of this over the past week. Due to the plumbing issues and then Toy Fair this past weekend, I'm only just now getting to post about this. Thanks to all who sent me info/links for this.
The following is a reblog from polygon.com.
Halo: Nightfall, the Xbox live-action series set between the events of Halo 4 and Halo 5: Guardians, will launch digitally on March 17, according to a trailer released by Microsoft ahead of the digital launch.
The Ridley Scott-produced series of episodes is being combined into a single, feature-length release that will be made available to rent or buy from video-on-demand services and on DVD and Blu-ray.
Halo: Nightfall tells the origin story of Jameson Locke, a "a legendary manhunter and agent with the Office of Naval Intelligence." Locke is also the playable co-star of next year's Halo 5: Guardians and will be played by actor Mike Colter.
Was it confirmed that Locke is playable? thats pretty cool.
