Master Chief...is a traitor? Yeah, we found that hard to believe too. But that's the premise behind the main conflict in Halo 5: Guardians. The Chief and his Blue Team have gone AWOL, while Jameson Locke and his Fireteam Osiris have been tasked with locating Chief and his team. All the while, a powerful alien menace is threatening to destroy the galaxy once again. Halo 5: Guardians is the biggest release of Xbox One's 2015 exclusive games lineup. Fans will get to compete in new multiplayer modes (Warzone and Arena), tackle the campaign co-op style and craft their own maps with the retooled Forge mode. These screenshots showcase just how amazing this new mainline Halo looks. The truth will be revealed come October 27, 2015.
