Early Access Game

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

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Early Access was a better option than crowd-funding because it gives immediate access to players whose feedback will be helpful in developing the final product. It also helps us initially with budgeting larger development teams for the game, such as improving graphics, artificial intelligence, combat options, sound and music, or other mechanics. In the future we would like to purchase more professional software to improve upon the visuals of the game. Sitting back and marvelling at your very own custom built castle will be even more satisfying with quality graphics and lighting!”

Approximately how long will this game be in Early Access?

“There are two key milestones for Early Access
First is to implement combat so singleplayer becomes more enjoyable: 1/2018 – 3/2018 (duel trainings and open field battles)
The second goal is to finish castle sieges (more complex AI, more unit types) 7/2018
Third part is to allow multiplayer, signaling the game leaving early access: 12/2018 (May change)
We want a completed singleplayer state first before we start working on multiplayer”

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

“With every patch the game will get progressively closer to the final version. At the very beginning of Early Access there will not be combat or multiplayer. Not all block pieces will be fully implemented yet and some may be of a lower quality temporary texture as visuals continue being improved. Of course optimization may not be perfect (this will be a top priority though), and not all destruction mechanics will be implemented as of yet.

However, in the very beginning of Early Access you will be given access to a creative mode to begin building your dream castles, including customizable flags. Some blocks will be interactive, such as gates, shutters, or doors. Some initial destruction will be implemented: you can begin testing defensive capabilities of your castle with catapults. Note that destruction support, new blocks implementation and optimization will be first priority within the first few months!

Game development tasks for leaving early access stage:

Building part
- improving quality of initial placeholder objects
- LOD optimization for all new objects
- Destruction implementation to all new objects
- Implement custom decal system
- Custom coloring, such as plaster walls
- Addition of new blocks
- Fixing broken connections between blocks
- Optimize collision detection

- Improve grass system, leading to better framerate, saving, and easier terraforming
- Improve the look of nature: better rocks, terrain, and vegetation
- Experimental voxel lighting system for dynamic lighting
- Weather system
- More map types and level design
- Minimap functionality
- Environmental effects, such as burnable materials and fire damage

- Refine character control and anatomy
- Implement proper ragdoll physics for realistic movement
- Improve navigation system
- Civilians and other NPCs spawning
- Civilian and guard patrol AI
- Introduce combat system
- Realistic damage system, such as weak spots in armour
- Combat optimization for wars taking place offscreen
- Archery combat
- Horses
- AI siege weapons

- Open field battles (AI)
- Castle sieges
- Tutorial campaign (5 missions)”

What is the current state of the Early Access version?

“At the earliest stage of release you will be able to build castles in creative mode, design flags, and walk around and inspect the castle (overlooking the occasional bugs which are on schedule for removal).. Please keep in mind that World of Castles is still on a long development path.”

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

“Those who support us throughout the development cycle earn our highest thanks and deserve a better price for sticking with us over the next couple years as we refine the game. To those that stick with us from the beginning, we would not be able to develop a refined game without your support and feedback.”

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

“The player community knows what they want and sometimes come up with better ideas than us developers. We are aware of this and continue to read comments on our YouTube channel, Facebook page, or here on Steam. If you have an idea, feel free to post it on one of our social media pages or contact us from the link on our homepage. If you notice a bug, please let us know so we can fix it as fast as possible.”

Merry Christmas patch

Greetings our players! :)

We wish you to enjoy your Christmas time, a lot of presents, delicious food and a lot of time to spend with your closest persons.

At first, we should apologize for very slow development. We are very sorry that this project had hopes to be developed in at least a small team (around 5-7 people) to bring a decent amount of new stuff per taken time. Which this project would deserve. Unfortunately you might see that the budget did not allow us to work more than in core team of one artist and one programmer which is crazy state as these high detailed things takes quite a good amount of time... On the other hand, we absolutely understand, that it is very fair to wait with purchase up to the time, when game brings at least some more playability. Two months ago we realized, that even though we will be able to bring village simulation at around promised time, it would still need some extra more features, to not look weird and have a positive effect on sales. For example time of day, when AI respects the time of day to determine their actions. And with that, there is more stuff connected to it as for example tree optimization, which will not work with the change of lighting... and so on...

So we had to do one quite unpleasant decision for you and to raise the budget for WoC from other game than WoC, which we will be able to finish very soon and will not need much time after release, so we will be able to fully focus on only WoC again. That game was already finished and should be released of January 2019.

What is important to you, is that we will give this game for free to all our WoC players for Christmas!!! :) Unfortunately before Christmas steam had too much work around, so we do not have verified steam page for that game yet and also steam does not support any way how to give you the free steam keys. So we will add the game to the World of Castles folder with the upcoming patch. Later we will try to find a way how to distribute keys to you directly so you will have a nice extra game in your steam library ;) You deserve it as an apology for all the problems we were and still are struggling in WoC.

That given game is Called Transport services and it is a dynamic transport tycoon game, where you try to solve passenger and good transportation among expanding cities. There are cars, trains or planes for your solutions. The game will cost for non-WoC owners 9.99$

There is a trailer:

I hope you will enjoy it. Just take in mind that you have even pre-release access, so it might have some bugs.

That's enough about transport services. Now go back to WoC. In the upcoming patch, there will be some new objects like this windmill. Do not expect any gameplay changes. The current state of dev version village simulation remains the same as two months ago. We made core mechanics for villagers, they are able to cut trees, gather apples from trees, take resources to storages. They do not have any free time activities after work yet. Just go sleep at night... Also, the AI does not know how to behave if something abnormal happens. So it will need some time to get solved and be somehow more playable... The patch is expected to be out 26.12.2018. I hope that the decision with transport services will show as correct and help us to give more to WoC again :)

Enjoy Christmas! And our new game :)

About This Game


We want to clarify why this game is being released in early access instead of using crowdfunding. One reason is that it introduces players to the basic mechanics of the game early on, allowing the community share ideas for improvement while the game is still being developed. Although we are a small team, we have worked diligently on this project for almost three years and still have a long road ahead of us until we can expand our development team to speed things up. So please be patient as we continue to improve the game and add new features. We want to deliver the final project as fast as possible, but we also want to ensure it is polished and optimized. We believe feedback from early access is the best way to ensure a quality final product.

Current state

- unlimited sandbox build mode

- Marshal walk mode and destruction model (for some blocks)
- flag customization tool
- your marshal skill tree and equipment tool.

Coming soon

- Duels (challange stronger and stronger oponents to be ready into real battles)

important notes

- combat and siege mechanics are not implemented yet.


Building your own castle

At the beginning you’ll have a small pool of starting blocks to build your very first castle. Develop your skills in combat to earn money and experience. Money will purchase more blocks to expand your castle. Experience levels you up, opening up new block types and other building opportunities. A higher level also earns you more fame, which indicates how many blocks and items you can use to build your castle. The more fame you have, the bigger and more elegant a castle you can build. Every piece has a specific use: ballistas for defence, beds for soldiers, and plants and art to improve the morality of the castle’s occupants. As the castle’s king, it’s your duty to provide the perfect balance of defence, occupancy, and morality. From this, what will begin as a small keep will evolve into a sprawling fortification with towers, steeples, and secrets.
  • Build your very own castle with no limit but your imagination and prestige
  • Build a castle from scratch or choose from prebuilt castles that you can modify or defend
  • Build according to realistic defence and physics
  • Use extensive terraforming to improve environmental defence or aesthetics of the castle
  • Tiny details to improve the look or functionality of the castle
  • Realistic physics: if you knock out the base of a tower, the entire structure will fall
  • Choose from over 200 block types
  • Customize your own flag
  • Customize your marshal and army loadout for defence and for offence


When fighting other players, the game’s balancing system ensures you and your opponent have similar levels, prestige, and fame. As the siege commences, the attacker deploys their marshals to the field while the defender sets up their marshals inside the castles at appropriate defence sites. As an attacker, take advantage of trebuchets and other siege equipment. As a defender, utilize your battlements and other historically accurate defence techniques. Command your marshals in battle or take first person control and engage in the fight yourself. As an attacker, eliminate the defending army or take the throne within a given time limit to win. As a defender, ensure you survive the time limit or kill off all the attackers. Battles are not just one-on-one: invite friends to help defend your castle too.
  • First person and top down combat depending on how you want to fight
  • Destruction of the castle is not permanent. Damage automatically repairs after combat
  • Dying in battle happens. You can still fight as you’ll switch to another marshal
  • Commanders deliver real-time reports of ongoing battles
  • Battles contain hundreds of units
  • Combat is realistic
  • Take control of various historically accurate siege weapons
  • Capture the throne or kill off all enemies to win an assault
  • Singleplayer combat options


From time to time we’ll publish short campaigns based on storytelling and role-playing. Some will teach players about intricate game mechanics and others will be inspired by true historical events. Campaign victories reward players with useful blocks, units, items, and other relics to improve their own castle. From the beginning, new players will have access to the tutorial campaign and one or two additional campaigns.
  • Adds engaging story elements to the game
  • Campaigns will be regularly updated, hopefully two new ones per year
  • Campaigns offer unique rewards for your castle to show off your achievements
  • Campaigns will consist of 4-7 missions


This game is still in development. Initial Early Access release may not have all these entire feature initially implemented but we will continue adding them over time. Follow Early Access release notes to keep informed about updates and additions.
