While searching the wreck of the ill-fated galleon Antocha, Edward managed to locate and loot several treasure chests that had sunk with the ship, gaining money and an upgrade plan for his own vessel, the Jackdaw.
- The ship's name is a variation of the Atocha, a real Spanish galleon that sank in a treasure fleet off Florida in 1622. Its treasure was salvaged in the 1980s.
- If Edward returned to the wreck, a tentacle coming from within the captain's quarters could be seen beckoning him. Looking through one of the room's windows would then trigger a short cutscene in which a white whale was attacked by a giant squid.
