The Sunken Kingdom

Do you dare seek the spoils of the deadly Sirens? Their Shrines and Treasuries are now laid bare to any sailor of the Sea of Thieves. Great wealth and knowledge await those brave enough to take the plunge, but the Sirens and Ocean Crawlers will protect it with their lives...

Siren Shrines

  • Created by the Sirens themselves, these newly uncovered Shrines were built with a wicked purpose. Their locations are charted on the ship’s map, and players reaching the marked spot will need to dive deep and swim through aerated waters to reach these mysterious monuments.
  • Siren Shrines pose a challenge to players’ puzzle-solving skills as they navigate obstacles to access hidden locations within these sunken structures. Coral treasures can be claimed along the way, and more determined explorers will find ever more treasure for the taking...
  • Players can visit six Siren Shrines: the Shrine of Hungering and Shrine of Flooded Embrace in The Wilds, the Shrine of Ocean’s Fortune and Shrine of the Coral Tomb in The Shores of Plenty, and the Shrine of Ancient Tears and Shrine of Tribute in The Ancient Isles.

Siren Treasuries

  • Siren Treasuries are additional undersea locations that will test pirates’ combat skills against a range of enemy threats. Players can expect to battle waves of hideous Ocean Crawlers, deadly Sirens and Coral Skeletons to unlock the Vault and escape with their Coral treasures.
  • Players can visit three Siren Treasuries: the Treasury of Sunken Shores in The Shores of Plenty, the Treasury of the Secret Wilds in The Wilds and the Treasury of the Lost Ancients in The Ancient Isles.

Coral Treasures

  • Exploring Siren Shrines and Siren Treasuries will reward players with new Coral treasures. Skulls can be returned to the Order of Souls, Coffers go to the Merchant Alliance, and Chests, Artifacts and Trinkets are gladly received by the Gold Hoarders. Siren Gems can be returned to any Trading Company representative.
  • While exploring the Sunken Kingdom, crews will be aided by friendly merfolk sworn to help those in need, in the form of Sunken Merfolk Statues. These statues allow players to deposit treasure for safekeeping while they explore an area.
  • Upon returning to the surface, players will be greeted by merfolk holding their collected Sunken Treasure in a clamshell on their back. When a player is ready to gather their spoils, only they can release this treasure for collection.

Coral Message in a Bottle Quests

  • As the Sunken Kingdom emerges from the depths, new items have begun washing up on shore across the Sea of Thieves. The familiar glint of glass may now lead players to a Coral Message in a Bottle, containing a note leading down to the Sunken Kingdom and the riches hidden beneath the waves.
  • By following these, players can uncover a unique treasure: the Breath of the Sea. Derived from the same power held inside Mermaid and Siren Gems, this can be handed in to any Trading Company for a generous reward! Three different rarities can be found, each worth more than the last: Sapphire, Emerald and Ruby.

Mysteries of the Sunken Kingdom

  • Scattered throughout the Siren Shrines, journals written by intrepid adventurers seeking the mysteries of the Sunken Kingdom await discovery by new explorers.
  • Players who locate all journals and learn the mysteries of the Sunken Kingdom should return to Larinna for a Legend of the Sunken Kingdom Voyage, offering an Enchanted Compass and a note leading to the first clue.
  • Players bold enough to forego the scholar’s warnings and unearth knowledge of the sorrowful secrets on the sea bed can seek an even greater prize, displaying their time spent below the surface…

Sunken Kingdom Commendations and Rewards

  • Within the Bilge Rats Reputation tab, new Commendations have been added for players seeking the waterlogged riches of the Sunken Kingdom. Completing these Commendations will unlock access to the remaining coral-encrusted items of the Sunken Sorrow ship and weapon sets currently held in the Outpost stores.

Sunken Kingdom Achievements

  • New Xbox and Steam achievements can be unlocked by progressing through the new in-game Commendations. A total of 200 gamerscore is available to earn from this update, and these achievements will remain in the game indefinitely.
