I bet you didn't know there was a Star Trek: Armada 3, did you? Well, technically there isn't, it's not a stand alone game, but it's a rather special mod for Sins Of A Solar Empire that effectively delivers what you would expect from a modern day Armada game.
Star Trek: Armada III begins with the first stirrings of the Dominion War and allows players to take command of five unique factions, the United Federation of Planets, the Klingon Empire, the Romulan Star Empire, the Cardassian Union/Dominion Alliance, and the Borg Collective. Explore strange new worlds, seek out new life and new civilizations, and boldly go where no one has gone before.
The latest release, for Sins Of A Solar Empure Rebellion, has a raft of new minor factions, which occupy planets within games and can either be destroyed or you can negotiate an alliance with them (Unless you're the Borg, of course) allowing you to convert them to your faction.
It's also got a lot of balance changes, with The Romulans no longer being quite as overpowered as they were, and The Borg being given a bit of a boost in early game scenarios where they were previously a little weak.
But as a huge Star Trek: Armada fan, I felt this mod needed some coverage, even if this release isn't a major overhaul of what is an already long standing and well respected mod.
