A 8 minute making of movie about Tomb Raider: Angel of Darkness, with several of the games developers describing the game in a voice over, and a tiny bit about how it was made, while some concept art, or game footage plays in between shots of the developers.
It might be a bit confusing, but there are a variety of teaser details on the plot and gameplay, which seems to be the main content rather then details of how the plot was conceived or the gameplay actually made (although there are some parts about concept to creation, and how the music was recorded).
It was put on Fileshack on Jan 15, 2003, and the game itself was released June 2003.
The people who are titled with doing the voice overs are, in order of appearance:
Jeremy Heath-Smith (Managing Director)
Adrian Smith (Operations Director)
James Kenny (Graphic Artist)
Mark Donald (Graphic Artist)
Richard Morton (Level Designer)
Paschal McGuire (Artist)
Jerr O'Carroll (Artist/Animator)
Phil Chapman (Artist/Animator)
Graham Gallagher (Artist/Animator)
Peter Connelly (Composer)
Martin Ivesen (Composer)
