How to find all Joker Teeth Locations in Batman Arkham Knight: A Matter of Family DLC
In Batman Arkham Knight: A Matter of Family DLC pack, Batgirl has to collect Joker's Teeth in order to unlock A Blade of Memory Trophy. Here are the exact location for the 15 Joker's Teeth shown below in Maps.
Firstly, complete the DLC story mode and then in free roam you collect/destroy the collectibles. The Joker Teeth are not marked on map by default so we recommend to use the Detective vision to find them when you reach in one of the below locations. The Joker Teeth are spawned in the outside area and not in any of the story buildings.
You can try the Batarang to destroy the Joker Teeth instead of climbing up and destroying it. Once you finish destroying all 15 Joker Teeth...BOOM! you can unlocked the achievement A Blade of Memory.
