During the Credits
There is an extra scene shown during the credits.
The extra scene shows Edward meeting his daughter in a semi-live scene that gives the player limited control. The credits break and then another short cutscene plays introducing Haytham and referencing the first memory of Assassin’s Creed III.
After the Credits
There is no stinger after the credits of Assassin’s Creed IV: Black Flag.
Special thanks to Richard Quintana for the stinger submission!
