Assassin's Creed Black Flag Resynced Collector's Edition comes full circle  with an Edward Kenway statue that helped leak the game months ago |  GamesRadar+

Grand Cayman in Assassin's Creed IV: Black Flag Resynced has 3 chests to find, but one of them is stopping players cold. It sits in plain sight on a clifftop at coordinates (357,298), visible from the ground with no obvious route up. No parkour angle works. No grapple point exists. The game is, for once, not testing your climbing skills at all.

The chest that isn't a climbing puzzle

Here's the thing: the secret chest at (357,298) is a social puzzle, not a traversal one. Next to it sits an old man getting berated for drinking too much. That's the hint. The game is practically winking at you.

To reach it, players need to visit the Grand Cayman tavern and buy 5 drinks in a row for Edward Kenway. The tavern may require completing a bar fight first to fully unlock it. After the fifth drink, a fade-to-black kicks in and Edward wakes up exactly where the old man was sitting, sprawled in a pile of palm leaves on the otherwise unreachable ledge. The chest contains the Yoke-Form Vessel, an art collectible, and players also unlock the "Hungover" trophy/achievement for pulling it off.

What most players miss is that the game is telegraphing the solution the whole time. The drunk NPC isn't set dressing. He's a breadcrumb.

Complete the Grand Cayman bar fight before attempting to buy drinks at the tavern. Without doing so, the drink-purchase option may not appear.

The other two chests and what they're worth

The remaining 2 Grand Cayman chests are more traditional finds, though neither is a simple walk-up.

Chest 1 sits at (358,295) on the southwestern side of the settlement near a cave pool with a Mayan statue. Players wade into the pool, dive at the bottom of the descending steps, and swim through a submerged doorway before surfacing inside a cave chamber where the chest waits. The reward is a handful of valuables worth a few hundred Reales, which makes it one of the less financially rewarding detours in the game.

Chest 2 at (365,303) on the northeastern side is the most straightforward of the three. It's sitting in a Spanish soldier encampment and visible from a distance. The only obstacle is the soldiers themselves, which means either a clean assassination run or a straight fight. Same story on the reward front: several hundred Reales in assorted valuables.

Why the drunk chest is generating buzz

Black Flag Resynced, Ubisoft's rebuilt take on the original 2013 pirate adventure, has been drawing attention for moments exactly like this. The game's willingness to use environmental storytelling as a puzzle mechanic, rather than relying purely on map markers and climbing routes, is something players are responding to positively.

The Grand Cayman secret chest is a small example of a broader design philosophy at work in the remaster. Compared to how collectibles and hidden loot function in something like Assassin's Creed Valhalla, where wealth and mysteries are mostly gated behind combat or specific abilities, Black Flag Resynced's approach feels more playful. The solution requires paying attention to the world rather than consulting a checklist.

The key here is that the "Hungover" achievement exists at all. Ubisoft built a trophy specifically around this interaction, which tells you everything about how intentional the design was. It's not a glitch that players are exploiting. It's a joke the developers wrote into the game and waited for people to find.

What comes after Grand Cayman

For players working through Black Flag Resynced's collectibles and hidden loot, Grand Cayman is one stop on a much longer route through the Caribbean. The Antocha Wreck, Anotto Bay's Smuggler's Den, and the Salt Lagoon each have their own chest puzzles and buried treasure to track down, with varying degrees of difficulty.

Players chasing 100% completion across the whole map will want a solid reference for every location. The gaming guides hub on our site covers the broader Assassin's Creed series and other adventure games with the same depth. For Valhalla-specific content, the Assassin's Creed Valhalla guide collection has everything from wealth locations to full story walkthroughs.
