As the book explains, the game is based on a 1950s German radio play ("Raumschiff Null" being a direct translation of "Spaceship Zero"). The German radio play was based on a 1930s American moviehouse serial called "Spaceship to the Stars" (which eventually became an American television show in the 1950s). The German radio play eventually spawned a German television show (of the same name) that aired from 1978 to 1980. And all this has spawned an American film production. The game plays off the ruse in a variety of ways. For instance, a section of the book is devoted to episode summaries from the "old television series". And fake websites, hosted by the games' authors, detail the film's production. The marketing of the CD is similar - being referred to and played-up as a soundtrack.
