Microsoft has given a timeframe and a subtitle to its first major new Halo game for the Xbox One. The game will be called Halo 5: Guardians, and it’ll launch in fall 2015. A Microsoft blog post describes the game as “the next installment in the legendary saga of the Master Chief.” Microsoft also plans to launch the Halo television series around the same time. Details are still scarce, with no additional trailers or screenshots to go along with announcement, and only vague promises of what the game will be like.
