Star Trek: Armada 3 is an upcoming mod for Sins of a Solar Empire: Rebellion. Beginning around the time of the Dominion war the mod will progress on it's own branching timeline. Players will have access to four races initially on release: The United Federation Of Planets, The Klingon Empire, The Romulan Star Empire and The Borg.
A few screenshots we picked up during our MP test of the recent rebalances. The battles now last a little longer and that really makes the atmosphere more star trek like.
