This 88 page document walks through the entire story of the game, as it was originally conceived... and fans will immediately notice some significant difference! Instead of two halves (on the Lexington and then the Intrepid), this early version was divided into three parts: it opens with an extended segment where Blair serves as part of a planet-based squadron on Nephele! That's not all -- each section has new characters, too... Nephele, for instance, includes Cmdr. Tyla Braverman and Chief Tech "Mutt" Malone.
Finally, one part may prove very controversial: this document seems to be the source of the Wing Commander movie's "Pilgrim" storyline: Border Worlders are distinguished by the fact that having spent generations in space has altered their genetics (brief references to this survive to the finished movie, such as Paulsen's speech about Border Worlders being from 'inferior stock'). Astute Wing Commander historians may remember that the Phoenix Pictures Memo, based on the original movie proposal, referred to Border Worlders rather than Pilgrims.
