Uncover the mystery of Oak Island. (4)

This trophy is similar to "Bring Down the House", except that you must find all of the 24 Peg Leg Trinkets and have completed the four previous missions associated with this side-quest. This can only be achieved after Sequence 8, as there are Trinkets to be found in New York.

Once you have returned all Trinkets to Peg Leg at the Homestead and completed all 4 previous missions, you will have access to an area known as Oak Island. You must complete the main objectives in the mission and find Captain Kidd's Treasure to earn the trophy.
