What the developers have to say:

Why Early Access?

“Sea Trials is a long age of sail tradition. Captains of that time had a chance to test their vessel and provide feedback to the Admiralty on what needs to be changed to make the ship perform better. Extensive sea trials are required by the Admiralty to fully test if the ships in the game are seaworthy and ready for fighting.”

Approximately how long will this game be in Early Access?

“We plan to stay in Early Access until core features of the game are finished and polished.”

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

“The game is in alpha. We plan to focus on the following during the Early Access
  • Improved User Interface
  • New ships
  • More features like production buildings, officers and better crew management and many other exciting things.

for more information please visit our forums.”

What is the current state of the Early Access version?

“Excellent age of sail combat representation
Basic crafting
Basic trading
Basic conquest
Multiple playable nations
Large variety of age of sail vessels

User interface is purely technical and will be improved once more features get into the game.”

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

“Price will go up when Early Access ends.”

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

“Naval Action community has been involved in the development from the start. We are very proud to say that many features the game has were proposed and designed based on community ideas. We plan to continue doing so going forward.

To share your voice and propose features please visit our Steam community forums or our company forums located here

Testbed: Content Patch 9.98 deployed today.

Hello Captains.

Patch have been deployed to testbed. Here is a brief description.

  • Challenges: PVE challenges now provide the ship for you. No need to purchase the ship anymore to participate in challenges.
  • 1 durability for ships of the line did not achieve its required goal and is removed. It did not have any effect on rich veterans and was just punishing casuals who left the game instead of converting into pvp/conquest players because they lost the ships they worked so hard on. All linesips now have 3 durabilities with the corresponding increase of required resources.
  • You can now use the hold of your fleet ships.
  • Admiralty store has been added for testing. The content is not final, prices are not final and what is sold in stores is mostly for testing the systems. The following rewards were added
    • City Key - for raids or port attacks or defences
    • Battle Ensign - PVP reward
    • Short Pennant - PVE reward
    • Trading Manifest - reward for trader ships or trading missions etc.
    • Each reward can be used for exclusive content in admiralty stores (test content to test systems provided in testbed).
    • All rewards are given in the end of battle based on battle kills and damage. If 10 people sink 1 ship rewards are split for 10 people based on damage, kills and assists.
  • Officers. Officers had one problem, they punished you if you played actively (and sank a lot). As a result officers were removed from the game and all perks have been moved to a player. You get 1 point per rank. The system is not final and will continue development. Officers in their traditional sense might come back in the future.
  • Pirate vs Pirate - outlaw battles. Pirates can now attack each other. The battle created by pirates vs pirates is always open and has FFA rules (free for all). You can sink anyone you see. Signalling perk does not work in the battle. Battle cannot be created in the capital protected waters.
  • Recently killed tracker added to game. Players who recently lost the battle (sank or surrendered) no longer give rewards for 1 hour. This solves huge number of problems for a minor price.
  • Ship paints can now be stored in clan warehouses.
  • Forts and towers were significantly buffed (large fort will destroy a ship in approximately 5 minutes under constant fire). We hope this feature will help players to vary their fleets a bit and bring mortar vessels to battles (who can destroy a fort in 10 mins. If this damage is too big we will lower it, but we were not really satisfied with the forts uselessness in battles.
  • Chain shot damage fall off from distance implemented and added to game.
  • All instances are now immediately closing when last player leaves the instance. A good % of instances were wasted for bot vs bot entertainment

    For information on how to get to testbed please check the previous announcement.

Test bed server opens - structure testing started

Hello Captains

Test bed has opened today.

Some disclaimers first. Testbed is not a stable environment. It does not have the same level of stability as main servers. Number of instances available is limited but will be enough unless everyone moves to test bed. This environment is not connected to the main server databases. We will provide some xp and money and ships for you to test things we want. Sometimes it wont work at all.

How to get access to the testbed
  • Find the game in your steam library
  • Right click and go to properties
  • Go to Beta tab
  • Enter the key - key FcaH2KzZXutz
  • Select the beta called: Testbed
  • And click close
  • It will download automatically.
  • To return to the main game select none instead of testbed in the beta tab.

Main test goal: Structural damage testing

Combat model updated. Structure introduced. Ship now receives structural leaks when structure goes down (not when armor is destroyed like before). Structure affects leaks and masts integrity (you will be able to demast by bow and stern raking). This feature requires heavy tuning that is why it is deployed to the test bed.
In the future we will also test a couple of other changes increasing the role of skill in combat allowing skilled captains to dispatch enemies faster (even outnumbered)

What’s new and other changes on the testbd
  • Port battle entry is only allowed 30 mins after login at sea. This penalty can be dropped if you enter any port. If you log off at sea and login within 5 mins (disconnects etc) you don’t get that penalty
  • Zone control points are not accumulated during first 10 mins of the port battle
  • New PvE challenge added – Timed demast
  • Tiered rewards are coded into the challenges and eventually we will provide different rewards for different positions in the leaderboards.
  • New sounds are added but not finalized yet.
  • Admiralty PVP events in admiralty zones are 6v6 now. Only 6 ships are pulled for each of the sides of combat.
  • PvE challenge ships should now change (rotate) automatically

  • Map zoom increased 2x in commander tablet
  • Port battle time increased to 105 mins
  • Accuracy and damage from land based guns increased by 15%
  • Points for kills increased by 50% in port battles instances
  • Antigriefing 5x limiter decreased to 4x
  • Attack circle timer (ow attack) reduced from 20 seconds to 15 seconds
  • Certain changes in economy applied
  • Time to start PVE challenge reduced (only for testing)
  • If you sink in battle you will still be able to see the compass and wind indicator
  • Brace command is now a toggle
  • All contracts that are more than 15 days long are going to be automatically cancelled from now on.

Main goal is - test structural damage and report the findings

About This Game

Naval action - open world multiplayer sandbox

Naval Action is an exciting, realistic, and beautifully detailed naval combat game immersing players into the experience of the most beautiful period of naval history - when sailing ships ruled the seas.


Exciting bugs – Because its still alpha we have an interesting selection of annoying, strange, and sometimes wonderful bugs. We are squashing them one by one, but it's Caribbean - they will keep coming for quite some time.

Enormous open world – Large open world, recreated based on 18th Century maps, historical harbors, positions, and town names. We do not believe in the various modern hand-holding markers, thus player position is not shown on the map: you will have to navigate yourself using compass, sun or landmarks. PS. battles are instanced to allow extremely complex sailing and fighting calculations for 50 ship battles.

Freedom – Build ships, trade, sink enemies of your nation. You can attack anyone almost everywhere. Remember that every action could have consequences. So don't attack everyone - or you will become a pirate. Conquer almost every port in the Caribbean, but remember! other adventurous captains will try to ruin your plans.

Beautiful ships – Accurate hull models, sail plans, guns, internal upgrades, historical speed, turning and heel performance. Ships from small cutters to large 100+ gun 1st rates will allow the player to experience every possible role of the Age of Sail period.

Realistic sailing – Advanced wind and physics model provides for realistic portrayal of ship’s performance in the age of sail. Yard angles, ship angle to wind, fittings and ship condition affects speeds and turning rates. Correct tacking, boxhauling, clubhauling and other elements of the age of sail sailing are possible. Hidden ship characteristics will allow to gradually uncover potential of the vessel – every ship in game will be unique.

Historical gunnery - Realistic ballistics and cannon performance of the period. Every cannonball is tracked in the air and after it hits the target. One shot can hit the stern, damage the rudder, then hit the cannon carriage, injure crew, ricochet from the floor and hit the opposite side. Listing and wind affects the shooting distance and will require change of tactics.

Weapons - All major types of naval artillery are implemented: from long guns to carronades. Fort and land batteries will provide support during port battles. Mortars are coming soon.

Damage model - Leaks, structural damage, torn sails, demasting, raking, fires and all other hazards that were possible in that era. Damage is positional: hit the gun and you might destroy it. Gunnery crews are placed deck by deck. Shot can pass through the balcony, ricochet of the gun, hit a crew member and then fly out of the gunport splashing into the water. Armor thickness and wood type is implemented and at extreme angles cannonballs will ricochet from the hulls.

Community driven development - Players actively participate in development and many elements of the game have already been implemented based on the player feedback. Content is immediately given out to players for testing and improvement. Share your thoughts in comments or on the forums.
