The Tau Empire fleet is coming to Battlefleet Gothic: Armada as a dlc. It's one of the first (the first being Space Marines) that's being brought in to expand the game's factions as Focus Home Interactive has announced somewhere that they will eventually have all the factions in the original tabletop game in the Battlefleet Gothic: Armada, so look forward to more! Tyranids, Necrons and even the Adeptus Mechanicus are rumored to have their own fleets coming soon, so look forward to it.
And here's an awesome trailer video for the Tau Empire.
Damn it, how dare those insidious xenos ambush the brave men and women of the Imperial Navy! They will suffer our wrath! By the way, I'm pretty sure the Imperium won the Damocles War, only to be forced to pull back because of Tyranid incursions elsewhere in the sector. Otherwise we would have kicked those blue Tau asses...
Except that we got our own asses handed back to us in Kauyon and Mont'ka so I probably shouldn't be gloating about the Damocles War. Oh well.
Worse, the 13th Black Crusade has just landed back on us (is it being retconned? What happened to the global 13th Black Crusade campaign or Eye of Terror Campaign a few years back? Are they going to ignore the results and go for a new storyline?), so it seems the Imperium will be attacked on all fronts as we move into the 42nd Millennium. Ugh.
But never fear, the Emperor protects! We will destroy all our enemies, be they heretical traitors or xenos filth! FOR THE EMPEROR!
