Microsoft released the live-action trailer for Halo 5: Guardians which, along with dropping more hints, announced the game's release on October 27, 2015. As with a teaser released last week, the new trailer hints at a story about Master Chief's fall from hero to traitor, at least in the eyes of some. It shows the Spartan-armoured Jameson Locke walking through a war-torn area, finally coming to a stop beneath a statue of Master Chief. At the bottom is the franchise hero himself, lying wounded. "All the hail the conquering hero, the one who was supposed to save us all," Locke says to Master Chief, before pointing a gun at his head. Halo 5: Guardians will be the first game in the series developed specifically for Xbox One, though the previous four main-series games are all available on the console, bundled together as Halo: The Master Chief Collection. Microsoft held a beta test for the multiplayer component of Halo 5 earlier this year; you can see our impressions of it here. Microsoft also recently launched Hunt the Truth, a blog and weekly audio series following fictional war reporter Benjamin Giraud's investigation into Master Chief's past.
