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".
