What the developers have to say:

Why Early Access?

“With the core development of Pirates of the Polygon Sea complete, we now need to test it; player feedback collected during Early Access will guide our development efforts as we add additional game features and content such as music, ships, creatures, characters, environments, etc.

For an indie developer such as us, Early Access grants two things that are essential to producing a quality game: 1) it allows us to receive feedback from our players that will help guide remaining development work, and 2) provides us with an influx of additional funds, allowing us to make as many improvements and additions as possible before release.”

Approximately how long will this game be in Early Access?

“Our Early Access started in July 2016 and we expect to release the game in 2017.”

How is the full version planned to differ from the Early Access version?

“The Full Release version of Pirates of the Polygon Sea will have more ship models, more abilities, more creatures, more environments, more characters, and more… everything really. Judging by how much we were able to include in the game for Early Access, you can look forward to many, many awesome features and additions over the coming months.”

What is the current state of the Early Access version?

“The Early Access version of Pirates of the Polygon Sea will feature all core game systems, including fully-realized (and awesome!) ship-to-ship combat, dynamic weather, an expansive ship selection, worthy AI opponents, a number of fearsome sea creatures, player events, and more.

Multiplayer will be released in the summer of 2017 – rest assured, we want to get you battling each other on the high seas as soon as possible!”

Will the game be priced differently during and after Early Access?

“During the Early Access program we'll be offering Pirates of the Polygon Sea at a reduced price to thank you for participating in our program. The price of the finished game will increase and the new price will be announced on release day.”

How are you planning on involving the Community in your development process?

“We'll be releasing a monthly game update and engaging the community in the steam forums for direct feedback. The input from those of you who play our game during Early Access will largely direct what we focus on for the remainder of development.”

Patch 0.3.2 – A Brand New World

The island loomed out of the mist, a heavy haze wrapping around its central mountain in a ring. As the ship crept closer, the mountain became a massive temple pyramid, its stepped sides covered in a thick layer of vines and creepers.

The scarlet-haired woman held a spyglass to her eye, observed the island for another few moments, then glanced down at the map she was holding. She frowned. This island appeared nowhere on the map.

“Wow!” The young raven-haired crewwoman exclaimed. “Would’ya lookit that! You have any idea where we are cap’n?”

She pressed against the ship’s railing, her eyes wide with wonder and a grin spread across her tanned, freckled face.

“I… have no idea.” Scarlett replied “It’s like this island just appeared out of nowhere...”

“We goin’ ta investigate?”


“Ya figure there’s sumthin’ shiny in there?”

“Very likely.”

“It prob’ly dangerous?”

“Most definitely.”

“I should fetch the rest o’tha crew then?”

“Oh yes. Absolutely.”

Scarlett’s trademark wicked smile came back as she watched Lily slide down the railing onto the deck below. She then turned her attention back to the mysterious pyramid and absentmindedly crumpled the map and let it fall overboard.

“Typical map-making pirate.” She muttered to herself under her breath.

“Leaving all the good stuff to himself...”

Welcome to patch 0.3.2 where we add all-new procedurally-generated islands to the game!

These new islands will be generated each time a new game is loaded and add far more variety and dynamicism to the game environment.

Tell us what you think about the new islands on the forums, we'd love to hear from you!

A whole new woooorld...!

Path 0.3.1 - Clever Girl...

The shark rushed at the boat’s hull, on a direct collision course with it’s mouth agape.

“Steady... STEADY!”

Jaerax exclaimed from the shoreboat’s deck, a harpoon raised above his head. He talked loudly and confidently to the 5 other men huddled in the small craft alongside him.

“See men? They always come at you in a straight line, you just hold your harpoon like so, and wait for it... NOW!”

Jaerax threw his harpoon. The shark dodged to the right. The harpoon splooshed harmlessly into the water.

The boat shook as the shark careened into it, tearing a chunk off the prow and biting a paddle in half before diving below the water.

Jaerax stood with a stunned look on his face.

“Huh. Well, they uhh... don’t usually do that. This one must be smarter than the rest.
... also, someone should patch that hole before we sink.”
There was a flurry of activity as a pair of crewmen started hammering planks onto the burbling hole.

The shark appeared again at the surface of the water over two hundred feet away. Suddenly, another fin rose from the water beside it.

And another.

And another.


A look of concern crept across Jaerax’s face.

“Stop what you are doing. Everyone grab a paddle, we make for the beach... now.”

The men scrambled over each other as they each snatched a paddle. Water splashed as all eight men began to hurriedly row. The boat lurched forward, speeding towards the sandy shore of the nearby island.

The sharks gave chase as Jaerax stood on the stern, one hand on the tiller and one clutching a harpoon, ready to stab the first shark that came near.
The boat hit the beach with a thud and the men scrambled out, pulling the boat the rest of the way out of the water.

Jaerax stood on the beach, his hands resting on his hips as he stared out at the fins circling the water between the beach and his ship.

A crewman sidled up beside Jaerax.

“Wadday ya figure cap’n?”

Jaerax frowned

“... I suspect we may have killed all the stupid ones. The only ones left are now smart, deadly, coordinated... and by the look of it, quite angry with us.”

“Your orders?”

“Get the boat repaired and have everyone carve spears from the jungle bamboo. We’re going back to the ship.”

“Aye cap’n!” the crewman remarked as he hurried off to join the others.

Jaerax looked back out onto the water. This was going to be fun...

They're Getting Smarter...

Welcome to patch 0.3.1 – Clever Girl, where the sharks have grown, much, much smarter (and more fun to fight).

We’ve also taken care of a few strange bugs and added a number of other small improvements.

Finally we have implemented a couple of all-new ship abilities for the scout and merchant class ships that match thier playstyle more closely than the mortar did. The warship class ships will still proudly use thier mortars as if nothing has happened.

Happy shark hunting!

New Content
  • Smart Sharks! – The shark combat AI has been revamped.
  • Ship Abilities – Scout and Merchant class ships now have unique abilities.

General Improvements
  • Tactical Turning – Ships moving slowly now also turn slowly
  • Shark HP Increase – Due to the shark AI changes, they became easier to fight. Now they are tougher.

Bug Fixes
  • Pink?! – Updating Unity turned our dolphins and fire pink. They are now no longer pink.

About This Game

Pirates of the Polygon Sea is a high-seas adventure where you play as a swashbuckler vying for control of the Mythic Isles. You will build a bustling port town, trade with neighboring islands, hunt for lost treasure, and if you dare, plunder merchant ships as a pirate. As your reputation grows, so too will your wealth and influence; with some daring and skill you may even rise to become lord of the high seas. Be sure to keep your cannons loaded and your cutlasses sharpened, however, for rumors speak of dark shapes spotted lurking beneath the waves...

Key Features
  • Engage in action-packed naval combat against enemy ships; fire broadside cannons, throw burning oil, and outmaneuver vessels in your quest to dominate the high seas.
  • Navigate raging storms, giant waves, deadly vortexes, and other dynamic weather effects as you sail throughout the world.
  • Build your humble coastal town into a bustling sea port, constructing docks, marketplaces, shipwrights, fishmongers, guard towers, and more.
  • Experience a dynamic, procedurally generated world; AI opponents, world layout, events, and objectives are randomized, creating a unique experience each time you play.
  • From mysterious shipwrecks, deadly pirates, and lost treasure to enchanting mermaids, giant whales, and even the legendary Kraken – you never know what you’ll discover when you set sail!
