Mojang has teamed up with Telltale Games, the folks behind the popular The Walking Dead games, to produce Minecraft: Story Mode, a standalone title based in the same universe as the open-world sandbox.
According to Telltale, Story Mode will have "an original story, driven by player choice" and will "mix new characters with familiar themes, in an entirely original Minecraft experience, inspired by the Minecraft community and the game that continues to inspire a generation."
There's no word yet on what the story and characters will be, but Mojang says it's not intent on "creating an 'official' story for Steve, or explaining the world of Minecraft in detail." (Steve is, of course, the name of Minecraft's player character.)
Mojang adds that Story Mode will come out in episodic form, much like Telltale's other games, with the first chapter due out "some time in 2015." You'll be able to play on Windows, OS X, Android, and iOS. Story Mode will also be out on "PlayStation consoles" and "Xbox consoles," which I assume means both current and previous generations.
