THE AMMO CRISIS: Why Millions of ‘Black Flag Resynced’ Players Are Losing Naval Battles (And How to Find the Secret Ultimate Storage Blueprints)
🚨 STOP WASTING YOUR REALES: You are fighting naval battles in Black Flag Resynced completely wrong! 🚨
Everyone is obsessed with grinding for Golden Cannons and Ultimate Rams, but they are getting absolutely destroyed by Level 60 Man-o’-Wars because their ship runs out of ammo in two minutes. The secret to making the Jackdaw practically invincible? The hidden “Ultimate Storage” blueprints that Ubisoft buried in the most obscure corners of the Caribbean map.
From a dead body near Tortuga to a secret chest buried directly behind a waterfall in Havana, these three treasure hunts will double your Mortar and Heavy Shot capacity. Get the exact map coordinates right here before your next naval bloodbath 👇🔥
The Caribbean Sea in Ubisoft’s critically acclaimed Assassin’s Creed Black Flag Resynced is a brutal, unforgiving warzone. For weeks, players have been dedicating hundreds of hours to transforming the Jackdaw—Captain Edward Kenway’s infamous pirate ship—into a floating fortress of destruction. They have braved suffocating underwater caverns for Golden Swivel Guns and raided heavily guarded Spanish convoys for Elite Cannons.
But a massive, infuriating problem is plaguing the community’s endgame naval combat: What good is a legendary weapon if you run out of ammunition after a single broadside volley?
Players are sailing into high-level combat zones, unleashing a devastating opening barrage, and then suddenly finding their Mortar and Heavy Shot reserves completely empty. Stripped of their heavy artillery, players are being torn to shreds by Pirate Hunters and towering Man-o’-Wars.
To solve this ammo crisis and survive the late-game naval battles, captains must hunt down the game’s best-kept secrets: The Ultimate Storage Blueprints. Thanks to a viral new guide by gaming content creator Aloo pc, the exact coordinates to these heavily guarded treasures have finally been exposed. Here is everything you need to know to stop running dry and start dominating the high seas.
The Problem with the Jackdaw’s Arsenal
In Black Flag Resynced, naval combat is heavily reliant on resource management. While your standard round shot cannons have infinite ammunition, they deal relatively low damage. To quickly sink elite frigates or capture coastal forts, players must rely on specialized, finite munitions.
Mortars are used to rain explosive damage from massive distances. Heavy Shot is an unguided, hyper-lethal volley used at point-blank range to obliterate enemy hulls. Fire Barrels are dropped from the stern of the Jackdaw to create a lethal, burning minefield to shake off pursuing ships.
Without upgrading the ship’s storage bays, the Jackdaw can only carry a handful of these specialized attacks. Running out of Mortars halfway through a coastal fort siege forces players into a deadly, close-quarters slugfest against heavily armored towers. The only way to increase this capacity to its maximum limit is by finding three highly specific treasure maps scattered across the Caribbean.
“Your Jackdaw can carry far more ammunition, meaning fewer supply stops and much longer naval battles without constantly running dry,” noted Aloo pc in his breakdown. But finding these blueprints requires embarking on three distinct, cross-map scavenger hunts.
Hunt #1: The Ultimate Mortar Storage (The Havana Waterfall)
The Mortar is arguably the most important weapon for softening up enemy fleets before they even enter your broadside firing arc. Maximizing its storage capacity is a top priority for any serious pirate.
The journey begins in the southern waters of the map. Players must set sail from the pirate haven of Great Inagua and head south toward the notorious port of Tortuga. Stopping their ship at the exact coordinates of 851, 352, players will discover a secluded strip of land. Lying in the sand is a rotting corpse clutching the first crucial treasure map.
Unlike standard treasure maps that offer vague sketches, this one is famously tricky. It points players toward the heavily fortified Spanish capital of Havana. Captains must fast-travel to Havana, take the helm, and sail slightly east to the coordinates 311, 617.
Upon arriving at this lush, tropical cove, players will notice a massive, roaring waterfall cascading down the cliffside. In true video game fashion, the treasure is hidden directly behind the rushing water. Digging up the glowing mound of dirt yields the Ultimate Mortar Storage Plan.
Hunt #2: The Ultimate Heavy Shot Storage (Cayman Sound to Petite Caverne)
If Mortars are your sniper rifle, Heavy Shot is your shotgun. Firing a full broadside of Heavy Shot into an enemy ship’s exposed weak point is the fastest way to cripple a vessel for boarding.
To secure the storage upgrade for this devastating ammo type, players must travel to Cayman Sound, located south of Havana. The map itself is hidden at the exact coordinates of 298, 311.
Interestingly, Ubisoft decided to show players a rare moment of mercy with this specific quest line. For weeks, the community has been complaining about the cryptic nature of treasure maps in Resynced—most notably the maddening, coordinate-free map tied to the controversial Blackbeard’s Secret Treasure quest.
However, upon opening the Heavy Shot map, players will realize there are no riddles, no vague sketches, and no geographic guessing games. Ubisoft simply wrote the exact coordinates of the buried treasure directly onto the parchment.
“This one is actually pretty nice,” Aloo pc remarked. “No riddles, no guessing, just straight to the point.”
Following the coordinates provided, players must travel all the way back to the southern sector of the map, specifically to the sprawling pirate cove known as Petite Caverne. By navigating through the winding tunnels of the cavern route, players will find the buried chest containing the Ultimate Heavy Shot Storage blueprint.
Hunt #3: The Ultimate Fire Barrel Storage (The Tulum Tree)
Fire Barrels are the ultimate defensive weapon, essential for shaking off relentless Level 60 Pirate Hunter ships that aggressively tail the Jackdaw when the player’s “Wanted” level reaches maximum capacity.
Conveniently, the map for the Ultimate Fire Barrel Storage is located in the exact same region as the previous treasure. While still exploring the caves of Petite Caverne, players need to navigate to the coordinates 862, 237. Here, they will find the final treasure map of the set.
Once again, Ubisoft spared players the headache of interpretation by printing the final destination directly on the map. The parchment directs captains far to the northwest, past Havana, to the ancient Mayan ruins of Tulum.
Upon arriving at Tulum, players must make their way to the sandy shoreline at the coordinates 41, 372. Hidden quietly underneath a massive, sprawling tropical tree, the final chest awaits. Digging it up grants the Ultimate Fire Barrel Storage plan, completing the trio of ammunition upgrades.
The Final Hurdle: The Economic Grind
While finding the three blueprints is a thrilling pirate adventure, veteran Assassin’s Creed players know that securing the plans is only half the battle.
Like the Golden Swivel Guns and the Ultimate Iron Hull, simply holding the blueprint in your inventory does not magically expand the Jackdaw’s cargo hold. Players must return to the harbor master at their hideout in Great Inagua to formally construct the upgrades.
This is where the game’s brutal economy rears its head once again. Purchasing all three Ultimate Storage upgrades requires a staggering amount of Reales (gold) and raw materials like metal and wood, which can only be acquired by boarding and plundering enemy ships.
For players who have neglected the game’s economy, this final step can trigger a massive grind. “If you’re short on materials or Reales, I’ve already made dedicated money farm and material farm guides that will help you max out the Jackdaw,” Aloo pc reminded his viewers, pointing to the ongoing community struggle to afford the game’s late-stage content.
Despite the hefty price tag, the investment is non-negotiable for anyone looking to conquer the Caribbean. With maximum Mortars to rain fire from afar, endless Heavy Shot to shred hulls up close, and an endless supply of Fire Barrels to cover their escape, captains who secure these three upgrades will transform the Jackdaw from a simple pirate ship into an unstoppable naval juggernaut.
Stop running out of ammo. Grab your maps, load your cannons, and go claim the seas.
