Two weeks ago, Microsoft revealed that some kind of Halo/Minecraft crossover was in the works for Minecraft: Xbox 360 Edition. Many people assumed it would be a Halo Mash-Up Pack similar to the previously released Mass Effect and Skyrim packs. Looks like those folks were correct as Microsoft announced that a Halo Mash-Up Pack will be available to download soon:
As with our previous Mash-ups, the Minecraft Halo Mash-Up Pack has some exciting features; exclusive Halo-themed texture set, Halo-themed menus & user interface, new-look items inspired by Halo, 40 character skins, and many music tracks from across the Halo series. This epic pack also includes an astonishing pre-made world, recreating some classic Halo locations like Blood Gulch, Sandtrap, and Valhalla, among many others…
More screenshots from the Mash-Up Pack can be found at the Play XBLA blog. And Microsoft has promised that more information related to the expansion will be released this week.
