Wing Commander I and II predate the era of 'day and date' hint books; in fact, the guide to Wing Commander I and II is a single book, released after both games had already been released! It's actually written in prose like a novel and contains a great behind-the-screens section detailing the making of the games. The book was available in English and German, although the German release removes the extensive 'making of' segments. Unofficially, two other books were published--Secrets of the Wing Commander Universe, a comprehensive guide to every game through Privateer, in the United States and another unofficial 'pilot handbook' in Germany. Finally, the first three Wing Commander novels--Freedom Flight, End Run and Fleet Action--are based entirely on concepts introduced in the first games. The first two books even ape the Wing Commander I and II covers!
