Microsoft has officially confirmed Halo content will be coming to Minecraft but did not specify details. The Skyrim and Mass Effect expansions offered not only character skins, worlds and items, but new music was added into the packs.
Since both the Mass Effect and Skyrim Mineraft expansions featured so much added content its expected that the Halo one will be just as elaborate. Minecraft is not available on the Xbox One yet but it is still playable on the 360. We will continue with updates on the Halo Minecraft expansion once more information is released.
