Legendary pirate Blackbeard (Edward Thatch) finally gets a dedicated treasure hunt in Assassin’s Creed Black Flag Resynced. Exclusive to the remake, the mission unlocks after completing Sequence 08: Do Not Go Gently and adds a satisfying narrative cap to the controversial Edward Thatch arc. Below is a step‑by‑step walkthrough.

Starting the Quest & Acquiring the Map

Progress through the campaign until you see Edward Kenway alone on a beach. He examines Blackbeard’s abandoned hat, granting two items:

• Burn Blackbeard’s Beard – a sea shanty your crew can sing while sailing the Jackdaw.
• Blackbeard’s Treasure Map – a crudely drawn chart showing an “X” north of Kingston, Jamaica, and a second “X” inside a barrel‑filled cavern.

Traveling to Anotto Bay

Enter the coordinates 591,243 on your in‑game map. Upon arrival at Anotto Bay, you’ll encounter several hostile pirate vessels. Use the Jackdaw’s cannons to neutralize them before proceeding.

Navigating the Underwater Caverns

After clearing the surface enemies, explore the water’s surface. Some smugglers have dived into submerged tunnels. Locate the wrecked diving bell and dive down. You’ll encounter jellyfish around a mining tunnel—avoid them as they damage Edward.

Continue through the tunnel until a shark attack prompt appears. Press the dodge button and tilt the left thumbstick left or right to evade. Bubbles indicate nearby air pockets for oxygen replenishment.

Descend beneath the wreckage, enter the first cavern, and repeat the process: place a red barrel against a collapsed wall, shoot it from a distance, and create an opening. Defeat the enemies in the water‑filled chamber, then repeat with a second barrel at the far end to trigger the next cutscene. Use barrels to blast walls in both the first and second caverns.

Chest, Map Fragment, and Final Rewards

Inside the smuggler’s den you’ll find a large chest that requires a smuggler’s key. The key‑bearing NPC does not spawn during the side‑quest, so revisit the area during free‑roam. The chest holds a map fragment, which can be decoded at the Treasure Dealer in Great Inagua. Another collectible points to a buried chest nearby.

When the final chest is opened, it contains only tools and goods, but also a letter from Blackbeard explaining that the items are meant to help rebuild your settlement in Great Inagua. Two months later, a cutscene awards you Blackbeard’s Portrait to hang in your manor.

Conclusion

While the treasure hunt feels light‑hearted for a notorious pirate, it enriches the Caribbean’s hidden content. Additional secrets, such as other treasure maps and Mayan stelae, are detailed in our related guides.
