As fans will no doubt spot, the Master Chief himself doesn't feature in the trailer. Instead, it focuses on several United Nations Space Command soldiers - who, in the game, back the player up - that appear to discover a mysterious alien threat. Most notable of all, however, is that it offers glimpses of Christina Chong, who featured in Doctor Who episode A Good Man Goes to War and has been recently cast in Star Wars: Episode VII, as Macer. It also stars Mike Colter as the show's protagonist Jameson Locke.
Nightfall will apparently tie into Steven Spielberg's long-mooted TV adaptation of the show, which is allegedly still being made.
