Users looking to find the Wing Commander Saga Macintosh port recently were out of luck -- the worldwide mirrors disappeared for reasons unknown! Luckily, the Saga team was able to send us a copy to post... so anyone who swings that way can pick up a Mac copy of the Saga prologue here (274.9MB, DMG).
This is the seventh set of Feng Zhu "concept" ships, commissioned for an unspecified Wing Commander title following the release of Secret Ops. This fleet of ships runs the gamut, including Border Worlds designs of all types and even more Kilrathi freighters and multi-role ships. The Border World ships are interesting, with effort clearly being made to give them a separate and possibly non-human design aesthetic... the Kilrathi ships are classics, though, and could be placed anywhere in the Wing Commander universe.
Thanks to Captain Johnny for both archiving and providing this material!
