What the developers have to say:

Why Early Access?

“Medieval Engineers is an Early Access game, which means that it is released while under development but is already in a very playable state and contains a vast amount of features. The game is being improved on a regular basis through updates that add and polish features and content, optimizations and bug fixes.

Getting real feedback from our community is our topmost priority. Working on a game behind the veil isn’t fun and is altogether much less effective. Real people with real needs and real voices you can listen to are the heart of game development. We invite all players to give us their feedback and suggestions and help us create the best game possible!

Buy now, play on Steam and receive future updates.

Everything in the game is subject to change.”

Approximately how long will this game be in Early Access?

“Medieval Engineers will remain in Early Access development until we gather enough feedback from the Community. We need to see how people play our game and what do they want us to focus on. Community feedback is expected and will direct our future decisions. We want to ensure that our players have the best experience possible and we will continue to develop the game in Early Access for as long as it is required in order to achieve it.”

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

“We are planning to release new updates on a regular basis. These updates will contain new features, optimizations and bug fixes. The same model has been used for our first Early Access title, Space Engineers (, with great success. New additions to the game will be also depended on player feedback.”

What is the current state of the Early Access version?

“The first release of Medieval Engineers will feature: Creative mode (unlimited resources, instant building, invulnerability, levitation), Steam Workshop (SDK + API), damage, and structural integrity. Multi-player and survival modes will come later. A full list of all the features can be found on our website:

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

“All players who decide to purchase the game in Early Access will receive future updates. The price of Medieval Engineers is going increase gradually for as long as it is under development and more features are being added.”

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

“Our studio has a very good reputation for developing Early Access titles and the way we involve our players in this process. Our first Early Access game, Space Engineers, is considered to be among the most successful Early Access projects on Steam. Getting real feedback from the Community is our topmost priority. Real people with real needs and real voices you can listen to are the heart of game development. There is a dedicated sub-forum where players can report bugs that they find in the game ( Players can also interact with the community and developers on our discord server

Update 0.6.2 Patch 8 - Minor Update

Hello, Engineers! This will be the final update to 0.6.2, now we will focus on polishing 0.6.3 to ensure its quality is as high as possible. In this patch we improved the speed at which inventory items transfer between inventories when you bulk-move large amounts of items, the respawn camera is now positioned correctly on your claimed respawn bed, and we solved an issue that prevented you from respawning when alt+tabbing in the respawn screen. Additionally, we have even further improved the performance with the fracture pieces, they should no longer freeze the game when a building just started collapsing. Switching toolheads in the mechanical crafting blocks will now return the resources that were being used, putting it in line with the other crafting processes at this time.
Enjoy the update, and see you with 0.6.3!

Update 0.6.2 Patch 7 - Minor Update

Hello, Engineers! This week we've optimized the memory use when buildings are collapsing, which also helps the performance on servers a little bit for small destruction cases. We tackled many of the edge cases causing foliage to 'blink', these were caused by minor slowdowns causing them to skip a frame, this made the foliage disappear for one frame which looked like they were blinking. We also enabled Structural Integrity view in Creative Multiplayer, and we updated the advanced weapons quest, it now has a proper notification and also accepts iron and steel crossbows. Finally, on the modding side of things, we have repaired the parallel interface in the ModAPI, so you modders out there can write code that runs parallel too.

About This Game

Medieval Engineers is a sandbox game about engineering, construction and the maintenance of architectural works and mechanical equipment using medieval technology. Players build cities, castles and fortifications; construct mechanical devices and engines; perform landscaping and underground mining. There is an entire planet to explore!

The game is inspired by real medieval technology and the way people built architectural works and mechanical equipment using medieval technology. Medieval Engineers strives to follow the laws of physics and history and doesn't use any technologies that were not available in the 5th to 15th centuries.

Medieval Engineers concentrates on construction aspects, but can be played as an action game too. We expect players to avoid engaging in direct man-to-man combat and instead use their creativity and engineering skills to build war machines and fortifications. Medieval Engineers shouldn’t be about troops; it should be about the machinery you build.

Medieval Engineers is the second “engineering” game developed by Keen Software House. The first one is Space Engineers, which sold over 2 million copies in its first year and is still a bestseller.

Early Access Features

    Medieval Engineers is all about building and the options are unlimited. Build anything from houses and castles to wagons and catapults.
    Change, pick up and interact with everything includes plants, bushes, trees, animals, and the ground itself. Everything is interactable and destructible!
    Make the ground into any shape you want. Use a pickaxe to dig and mine in the ground or use the special voxel tools to reshape the land.
    Play in a volumetric open world environment and explore a whole planet. Find valuable defensible areas or go to battle alongside your allies to take enemy lands and secure resources. The planet is full life including trees, plants, animals, and savage barbarian warriors.
    Build with structural integrity. Make buildings too tall and they will collapse! Design your structures carefully keeping in mind the differences between wood and stone. Use Structural Integrity View to find weak points in real-time. When the supports fail buildings come crashing down in glorious real-time destruction!

Performance Notes

Medieval Engineers is in development and undergoing frequent optimizations. The performance will get better. The performance depends on the complexity of your world and the configuration of your computer. Simple worlds run smoothly even on low-end computers, but a more complex world with rich object interactions could overload even high-end computers.
Minimum requirements represent the bare minimum to run simple scenes and don’t guarantee a perfect experience.
