Halo Online was a free-to-play, multiplayer-only Halo title that underwent testing solely in Russia. On August 24, 2016, the developer, Saber Interactive, announced that "the current form of Halo Online will not be released," effectively canceling the game. The stated reason for the cancellation was that Microsoft had "failed to [make] decisions on the future of the project."
