From Star-Trek-Games.com:
Mike Strobel has released a new update for Star Trek: Supremacy. This latest update now contains a race selection screen that allows you to choose to play as any one of the five empires; not just the Federation. The new empires do not yet have their own interfaces; these will be coming in a future update.
You can download the update simply by running the game; it will automatically notify you of the update when you run it. If you haven't yet downloaded Supremacy, you can download it from This Thread.
WOW.
Thanks Mike. You Rule!
Hows the AI coming ?
