Assassin's Creed IV's Freedom Cry DLC, which deals with first mate Adewale's mission to free as many slaves as he can, will drop on December 17th. Taking place a few years after the core story, Freedom Cry is a mini-campaign that will host "over four hours" of content according to Ubisoft.
At first, I was skeptical of the DLC given the relatively underwhelming King Washington add-on chapters for Assassin's Creed III. But after actually playing Black Flag I came around to the idea, especially considering the fact that I loved Adewale's character. With the right story, this could actually be a really neat series of DLC -- let's hope they don't screw it up. Expect some impressions closer to launch.
