Nearly five years on, Microsoft has finally gotten its Halo TV series greenlit and into production.
Cable network Showtime has ordered 10 episodes of the show, which it is calling its "most ambitious series ever".
Entertainment Weekly reports the show's blurb as "an epic 26th-century conflict between humanity and an alien threat known as the Covenant. Halo will weave deeply drawn personal stories with action, adventure and a richly imagined vision of the future".
The series has a showrunner, writer and executive producer in Kyle Killen, who created the short-lived fantasy police procedural Awake.
Rise of the Planet of the Apes director Rupert Wyatt has been signed as the director of multiple episodes.
"We expect audiences who have been anticipating it for years to be thoroughly rewarded," Showtime boss David Nevins said. "Kyle Killen's scripts are thrilling, expansive and provocative, Rupert Wyatt is a wonderful, world-building director, and their vision of Halo will enthrall fans of the game while also drawing the uninitiated into a world of complex characters that populate this unique universe."
It's been a long wait. Microsoft originally spoke about its plans for a Halo TV show in 2013 - remember when Spielberg popped up? - years before Halo: The Master Chief Collection arrived and had all those issues, before Halo 5, and long before Halo Wars 2. After this long - can it please be good?
