Early Access Game

Get instant access and start playing; get involved with this game as it develops.

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.”

Path 0.3.0 - Wind and Waves!

A cannonball sailed past the ship’s stern, splashing into the water close enough to send a spray of water over the deck.

“Cap’n! They be gainin’ on us! What da we do?”

“Are they? Hold fast our course Mr. Smith, that’s an order.”

The blonde man’s eyes narrowed dangerously as he stared at the approaching ship, its black sails fluttering in the wind. He lifted his tricorn hat off his head and held it in the breeze, tilting it slightly to feel how the wind caught it. He plopped it back on his head.

The pirate ship was indeed gaining on them. It had been getting ever-closer over the course of the past hour and its guns were almost within range of the Deadman’s Revenge.

“Let them come...” Captain James Corben growled under his breath.

“Mr. Smith! Kindly ready the helm to turn ninety degrees north on my mark. Mr. Ellis?”

“Yes cap’n!” The bald, bearded quartermaster shouted back from the deck below.

“Ready all portside guns to fire on my command.”


There was a flurry of activity below decks as gun crews scrambled to load their cannons.

James held his tricorn hat above his head again, feeling the wind subtly shift and flow around it. He glanced at the helmsman beside him.

“Mr. Smith?”

“Yes cap’n?”



With a practiced motion, the handsome young helmsman braced himself as he hauled the wheel hand-over-hand two full rotations to the left.

The Deadman’s Revenge immediately started to list heavily to the right, its cannons almost dipping into the water as it began to turn.

Suddenly, a crosswind filled the sails and the entire ship lurched forward out of the list, rocketing forward and coming about. It’s cannons now aimed directly at their pursuers.

“Fire!” Captain Corben commanded.

“FIIIRRRE!” Deckmaster Ellis shouted.

The ship shook as all twelve guns fired in unison, smoke billowing out the barrels.

The cannonballs ripped mercilessly into the pirate ship, punching giant holes in its hull and splintering the deck.

“Mr. Smith, keep us on target. Mr. Ellis, prepare a second volley!”


The wounded pirate ship, its sails torn and deck ablaze, attempted to turn southward to bring its remaining cannons to bear on its suddenly very dangerous prey… its black sails suddenly shifted backwards as it sailed headlong into the crosswind.

The pirate vessel lurched to the side and immediately began to slow, a ragged, misaimed volley from its cannons splashed harmlessly into the water not even halfway to their target.

The Deadman’s Revenge continued to pick up speed as it circled behind the now helpless pirate ship.

James sighed. Perhaps these pirates were good men once. Perhaps they had families and lives. Perhaps they still do. But they had hurt people, and for that they needed to be stopped.

“Finish it.”


The Deadman’s Revenge shook. Cannonballs flew and smoke filled the air. Explosions rocked the now aflame pirate ship as men began to jump into the water.

Captain James Corben adjusted his tricorn hat as he looked upon the scene. A satisfied look crept across his face.

These pirates would never harm anyone ever again.


Also, welcome to patch 0.3.0, where we introduce WIND!

That’s right! Wind has come to Pirates of the Polygon Sea! The new wind mechanic grants a speed boost to ships that manage to sail in its direction.

But beware, all ships can benefit from mastering the wind, so hone your sailing skills lest ye be left behind in the dust and spray!

Additionally, we have implemented our glorious, beautiful, sparkling new water solution. Bask in its beauty as the azure waves lap at golden shores.

So... kick off your boots, take a trip to the Enchanted Isle, and swim with the mermaids for a bit, the water is calling!

Oh, we also added two new mission types, a new player island layout, increased the world size by +50%, and added multiplayer.

So yeah, we’ve been busy. Happy pirate’s day.

Patch 0.2.0 - It Took Me Leg!

The large, muscular man reached over with a scarred hand and tore off the wanted poster from the rum-stained board.

“Huh? Some old pirate wants revenge on the shark that ate his leg. Cap’n, you see this?”

Jaerax leaned back in his chair to regard his crewman. The scar above the eyepatch on his right eye twitched, as if trying to frown. His remaining eye narrowed skeptically.

“A shark? Really? What is he paying?”

“Says here 500 gold…”

“Who would pay 500 gold to kill a shark because of a grudge?”

“Looks like his name is Jhon “Scaliwag” Hendrs…”

“That was rhetorical, Tarthus. I don’t care what his name is.”

“Right sir. So… uhh, we gonna take the job?”

“To find a random shark somewhere out there in the vast sea in order to settle a grudge by a crazy old pirate?”

“... A pirate with 500 gold.”

Jaerax grunted.

“Point taken. How much did the fishmonger pay us for the carcass of our last kill?”

“Err, fifty two gold cap’n. He was an ornery sort, wouldn’t pay any higher’n six gold per tentacle and ten fer the beak.”

“Damn cheap seafood hucker! Wish we hadn’t lost one of those tentacles in the fight...”

Jaerax sighed and snatched the wanted poster from Tarthus’ hand and studied it with his eye.

“Return to the Predator, see if they’ve finished repairing the sucker damage on the hull from that last fight. Prepare the ship for castoff as soon as its seaworthy. I’m going to pay a visit to an old pirate…”

Welcome to patch 0.2.0, where we introduce SHARK BOUNTIES!

Pirates aren’t the only dastardly villains on the high seas; the sharks of the Mythic Isles have grown bolder, preying on merchants, menacing fishermen, and occasionally, eating the delicious limbs of sailors thrown overboard. The people of the land have grown wary of these new emboldened toothy threats and have begun to post bounties for any brave captain to slay the dastardly beasts. Jaerax will be happy to hear his skills are valued by more than just the fishmongers.

Additionally, the victory condition in Pirates of the Polygon Sea has been completely re-designed. The old system of paying gold for new ranks on the way to Governor has been scrapped. Instead, whenever a player does anything of note in game: finding treasure, killing a pirate, searching a shipwreck, slaying a beast, rescuing a stranded sailor, completing a quest, etc, they gain an amount of “Renown.”

When a player has collected enough “Renown,” they automatically increase to the next rank. Renown cannot be purchase for gold, and gold no longer contributes (directly) to overall progress in any way, allowing you to freely spend your gold on building your town and upgrading ship without worrying about it affecting your victory progress.

Finally, we have replaced the placeholder missions with real, actual wanted poster-style missions dripping with flavour and world lore. So dive in, and get to know the people of the Mythic Isles better than you ever have before as you involve yourself with their goals, tragedies, and triumphs… and earn a bit of money and renown along the way.

Be aware, however: anyone with a scrap of paper and a chunk of charcoal has the ability to pin a poster on a tavern board, so be prepared for some, uhh… variation in writing ability.

I’m sure it’ll be fine, you speak drunken semi-literate fisherman, right?

Happy sailing! And may fate smile upon you on your quest for fortune and renown!
