Assassin’s Creed IV: Black Flag Crooked Island Animus Fragments Locations
Animus Fragment 1
The first collectible you can retrieve on Crooked Island, when you visit the area for the first time, is Animus Fragment #1.
Located east from the harbor, the fragment floats between two huts. One of them includes a ledge on the roof.
Place Edward on it and jump on the roof of the next cottage. After you get the fragment turn around and look down to see an isolated patch of sand and a palm tree. Explore it to find the secret on Crooked Island.
Animus Fragment 2
The second Animus Fragment is on a catwalk that connects two huts. Walk on it after you climb one of the buildings.
Animus Fragment 3
The final Ac4 Animus Fragment on the island can be collected after the last chest because it is around the corner of the house where the chest is located.
It sits on top of a pillar on which you have to jump using the poles around it.
