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

About This Game

Naval action - open world multiplayer sandbox

Naval Action is a hardcore, 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.
