What the developers have to say:

Why Early Access?

“Medieval Machines Builder gives players the chance to not only have fun but also to learn about medieval warfare, building war machinery in dark ages and medieval times itself.

Early Access gives players the chance to contribute to development and also gives us the opportunity to discover new game and content ideas. Creating a game is also a challenge like the construction process - we face various conditions and use many tools to provide you - our players - with the best possible ways to play, relax, rest, but also learn.

We have decided to launch in Early Access to maintain our close relationship with the community as we continue to implement more and more features by tinkering with the mechanics. We believe that with community feedback and participation we can deliver a better experience”

Approximately how long will this game be in Early Access?

“We anticipate that the game will be in Early Access between 6 and 12 months. But we don't want to be obligated with this as the game and the players are most important. We plan to remain in early access until we decide that the game is complete. We will be releasing major content updates, as well as smaller updates that will focus on specific aspects of the game. We will continue to listen to feedback from our community and work on improvements to the core of the game.”

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

“We want to improve the game and focus on providing as best gaming experience
possible. The final version of the product will include:
- new features
- new levels
- improvements of the already existing levels
- new war machines
The changes will also depend on the feedback of our players. We are here and we are listening to you - and you let us know what you need.”

What is the current state of the Early Access version?

“Early Access is fully playable! Please refer to the "About this" section for further details.”

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

“The full version of the game will be more refined, improved with a lot more content therefore its price may be slightly higher than in Early Access, but it will certainly offer many more mechanics and more complex functionalities from the EA version.”

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

“Your comments will be vital in our efforts to make Medieval Machines Builder best simulator game about dark ages war machinery. We want to hear from you about anything you think is important! Our discord: is also fully open to you, so you will be able to talk directly with the developers!”

About This Game

Step into the boots of a medieval engineer and master the art of siege warfare. In Medieval Machines Builder, you design, build, and operate powerful war machines capable of bringing down even the strongest fortress walls.

Gather resources from the world around you — wood, iron, rope, and more — and use them to construct iconic siege engines such as catapults, trebuchets, ballistae, and other devastating contraptions. Every machine requires careful planning, precise assembly, and ongoing maintenance to keep it battle-ready.

But building is only the beginning.

Test your creations on the battlefield, unleash their destructive power, and watch as stone walls crumble under your engineering genius. Adjust, repair, and optimize your machines to improve their efficiency and destruction potential.

Build Weapons of Destruction


Design and construct powerful siege engines from the ground up. Combine different parts and mechanisms to create machines capable of devastating enemy defenses.

Gather Materials


Venture into the world to collect essential resources like wood, iron, and rope. Without the right materials, even the best designs will never come to life.

Destroy and Shatter


Put your machines to the test and unleash pure destruction. Tear down walls, crush defenses, and watch fortresses collapse under your firepower.

Maintain Your Machines


Keep your siege engines in top condition with regular repairs and upkeep. A well-maintained machine is the key to consistent and reliable destruction.

Key Features:

  • Build a variety of authentic medieval siege machines

  • Collect and manage resources to craft your war engines

  • Maintain and repair your constructions to ensure peak performance

  • Experiment with different designs and mechanics

  • Destroy fortified walls and structures using realistic physics

From blueprint to battlefield — become the ultimate siege engineer.
