These manuals were released on Xbox.com, free to the public. They were a batch of manuals made available as part of Xbox Originals and other programs when full sized games were being made available digitally over Xbox Live. The push to include manuals for all digital games didn’t seem to go much beyond this list, and some Originals, like Psychonauts, Crimson Skies, Fuzion Frenzy, and a few others, have seemingly been removed from the website.
