Firelock Games has had quite a run on Kickstarter. Their campaign for Blood and Plunder has made it to over 10x funded. As such, they've unlocked the Pirates. Seems fitting that a game named "Blood and Plunder" would let you take pirates.
They're also working their way ever-closer to the French as a faction of choice. The campaign's in their last 24 hours, so if you'd like to get in on the action, you'd best get your buckles properly swashed and swing into action.
