| The San Ignacio Wreck is visited during the story campaign, but if for some reason you missed something and need to return the information has been covered here as well. |
Start by heading to the nearby Treasure and then swim past the barrel and into the broken hull behind the three jellyfish for another Treasure. Use the barrel to get some air and then get the Animus Fragment from the mast of the ship, stopping inside the nearby hull for another Treasure. Now head for the glowing hatch and open it, stopping to get air, and enter. Interact with the chest for a scene and then swim through the tunnel to an air pocket.
Dive back down and continue through a rough current, where you need to avoid colliding with objects, and when you exit you will meet up with a friend who is quickly devoured. Use the barrel nearby to catch some air and then hide in the seaweed. When the sharks swim away, head for the hull to the right and get the Animus Fragment. Exit into the seaweed and get the two Treasures nearby and then stop at the Diving Bell for some air. Return to the seaweed once again, to get the final Animus Fragment and Treasure you passed before leaving the area for good.
