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.
"Worf. Klingon species. A warrior race. You, too, will be assimilated."
"The Klingon Empire will never yield!"
"Why do you resist? We only wish to raise quality of life. For all species."
"I like my species the way it is!"
"A narrow vision. You will become one with the Borg. You will all become one with the Borg."
I assume we get along with the assimilated Starfleet ships now the Klingon ones too. Wonderful! ;)
