Minecraft: Story Mode
Is an Xbox Live account required to download episodes?
Yes. An Xbox Live account is required to download episodes through the Xbox Marketplace. However, an Xbox Live account is free to make and use. A paid subscription level (Gold) is not required to download any of the episodes.
A free Xbox Live account can be created directly on your console, or on Xbox's website here. Once you have created your free Xbox Live account, please sign into it, then launch the game. You will then be able to download episodes.
