The University of Texas at Austin's Briscoe Center for American History has digitized several VHS tapes donated by famed Origin producer Warren Spector including a VERY interesting tape previewing Origin's 1991 lineup. The tape, likely created for a trade show or as a preview for distributors, walks through all of Origin's current releases. It includes a lengthy trailer of the already-released Wing Commander I, The Secret Missions and The Secret Missions 2: Crusade… and then a VERY exciting preview of Wing Commander II.
Why is it so exciting? Because it shows an early build of the game that includes a number of different graphics, features and cutscenes! Pay special attention to the more complex turret interface, the 'profile' view of Blair in the comm room and a whole host of landing and takeoff scenes which do not appear in the final game… even a sequence showing the player landing their Epee on the TCS Agincourt! This is a video that's not to be missed.
