Star Trek: Armada II

Armada II sounds like a perfect sequel. In addition to the Federation, Klingon, Romulan, and Borg playable factions from the first game, Armada II also lets you play as the cruel Cardassians and the enigmatic yet decidedly hostile Species 8472, though these two are only available in the skirmish and multiplayer modes. New ships and technologies have been added to each of the returning factions. There's a new, linear campaign consisting of 30 single-player missions--10 for the Federation, 10 for the Klingons, and 10 for the Borg. New tactical options are available--ships can be set into a number of formations, and battles now play out in true 3D space
