Notorious Trophy in Assassin's Creed III: Liberation
Move through New Orleans for 10 minutes in the Assassin Persona
How to unlock Notorious
Simply walk around in New Orleans with the Assassin Persona for 10 minutes. You'll prefer doing most of the missions with this persona, so it should come naturally. I unlocked it during one of the first Acts, so it's near impossible to miss this one during the story.
