Assassin’s Creed Freedom Cry was DLC for Assassin’s Creed 4 but can now be purchased as a stand alone game on Steam you do not have to buy AC4 first. In Assassin’s Creed Freedom Cry you play as Adewale, an ex-slave turned Assassin fighting for freedom with the help of his own Pirate crew.
Born a slave, Adewale found freedom as a pirate aboard Edward Kenway’s ship, the Jackdaw. 15 years later, Adewale has become a trained Assassin who finds himself shipwrecked in Saint-Domingue without weapons or crew. He now has to acquire a ship and gather his own crew to free the slaves and avenge them. Over 3 hours of new single-player gameplay!
Playing Assassin’s Creed Freedom Cry doesn’t require a copy of Assassin’s Creed IV Black Flag.
