Homeworld 2 meets Star Trek: Armada 2. Set in over all four Star Trek eras you will find three superbly balanced factions to face off against one another, the Alpha Quadrant superpowers! The versatile United Federation of Planets, the formidable Klingon Defence Force and the enigmatic Romulan Star Empire.
The Ambassador class will make an appearance as an end-of-research-tree vessel in the TMP era! As we have set the TMP era in the early 24th century it's totally plausible :)
