When Ubisoft launched their highly anticipated remake this month, they had grand plans for a multi-week event. The official Assassin's Creed Black Flag Resynced Community Treasure Hunt was designed to dole out one cryptic clue every Friday throughout July. However, the game's dedicated player base had other plans. Eager captains bypassed the drip-feed completely, using sheer luck and relentless exploration to uncover all the Black Flag Resynced hidden chest locations in a matter of days.

If you want to skip the waiting game and claim your legendary loot right now, this comprehensive Black Flag Resynced coordinates guide will point your ship in the exact right direction. We will show you exactly where to sail the Jackdaw to immediately unlock 4,000 Reales, the legendary Uncrowned Prince Rapier Black Flag Resynced players are obsessed with, and the highly sought-after Black Flag Resynced Explorer Outfit.

The Ubisoft Community Treasure Hunt Explained

Shortly after the game's release on July 9, 2026, the developers kicked off the Ubisoft community treasure hunt. The premise was simple: each week, the studio would drop a clue on their social media channels pointing players toward an unmarked underwater chest containing exclusive rewards.

Pirates are not exactly known for their patience. Thanks to resourceful Reddit users like "-Holliday," players realized these chests actually spawned in the world on day one. Because they do not show up on the map natively and aren't highlighted by Eagle Vision, players literally had to look for bubbles on the ocean floor to spot them. Now that the secret is out, anyone can dive down and open the AC Black Flag Resynced community chests without completing any prerequisites or waiting for the official Friday riddles.

Black Flag Resynced Coordinates Guide: All Hidden Chest Locations

You can grab these three secret hoards in any order. Remember that because these are unmarked chests, you will need to sail directly to the coordinates, drop anchor, and swim down to the seabed to claim your bounties.

Chest 1: Dry Tortuga (421, 939)

Your first stop on the treasure hunt takes you to the far northeast reaches of the map. Sail to the Dry Tortuga region and align your vessel precisely with the coordinates (421, 939). You will spot a large rocky outcrop jutting out of the waves.

Dive directly downward on the northwestern side of this rock. Search the nearby corals carefully, keeping your eyes peeled for a faint trail of bubbles leading to the seafloor. Opening this first unmarked chest rewards you with a hefty 4,000 Reales. While it might just be pocket change for late-game players, this cash injection is incredibly useful if you have just started the campaign and need immediate Jackdaw upgrades.

Chest 2: Charlotte (500, 168)

Next, plot a course west of Kingston into the Charlotte sea region. Navigate toward the small alcove situated northeast of the famous Blue Hole shipwreck until you reach the coordinates (500, 168).

Once you arrive, dive down into the rocky crevices. You might need to swim slightly east along the coral formations to spot the chest tucked away in the shadows. This chest is where the rewards get exciting. Cracking it open grants you the legendary Uncrowned Prince Rapier Black Flag Resynced weapon, a stunning blade that offers bonus healing on takedowns. You also receive the legendary Guardian Beast Figurehead, allowing you to give the Jackdaw an intimidating new look.

Chest 3: Chinchorro (28, 292)

The final and most anticipated chest is hidden away in the Chinchorro region, tucked into a treacherous cove north of Corozol at the exact coordinates (28, 292). Be warned: two high-tier Spanish galleons actively patrol this narrow waterway. Because the passage is incredibly tight, avoiding a naval battle is almost impossible. Make sure your hull armor and broadside cannons are sufficiently upgraded before attempting this run.

After clearing the hostile ships or successfully outmaneuvering them, drop anchor and dive deep into the cove. Your grand prize for opening this third chest is the Black Flag Resynced Explorer Outfit. Many fans feared this red and white traditional Assassin garb had been completely cut from the remake, but it turns out it was simply hidden at the bottom of the sea. You will also earn the legendary Aveline Figurehead to complete your nautical cosmetic collection.

Diving Tips for the AC Black Flag Resynced Community Chests

Tracking down these secrets is thrilling, but underwater exploration in this remake comes with its own set of dangers. Since the AC Black Flag Resynced community chests do not glow brightly like standard collectibles, visibility is your biggest enemy. Adjust your camera angle while swimming to spot the distinct air bubbles rising from the chest lids.

Additionally, if you are struggling with oxygen depletion while searching these locations, consider toggling the newly added unlimited oxygen accessibility setting in the options menu. This allows you to explore the underwater environments at your own pace without the constant dread of drowning, making the hunt for these legendary items a smooth, stress-free experience. Grab your gear, set sail, and claim your rightful place as the wealthiest pirate in the Caribbean.
