Medieval Engineers is a sandbox game about engineering, construction and the maintenance of architectural works and mechanical equipment using medieval technology. Players build castles; construct mechanical devices and underground mining. There is an entire planet to explore!
Developed by Keen Software House · Published by Keen Software House









Players take the role of medieval builders and engineers in an open-world sandbox, using medieval technology to create settlements, castles, and fortifications.
Construction uses individual components and structural integrity rules: supports affect whether buildings stand, and physics-based destruction can bring structures down. Players can also assemble mechanical devices, engines, and siege machines.
Beyond building, players gather resources, craft, reshape terrain with voxel tools, mine underground, and explore a planet populated by plants, animals, and hostile barbarians. The game can be played as a survival experience or focused on construction.
In this sampled set, a recurring criticism is that official development ended and the game feels unfinished; some reviewers also report unstable physics, bugs, or crashes. Positive comments highlight component-based, physics-led construction and the freedom to build structures and machines. Some reviewers say community mods or the Community Edition make the game more enjoyable, while others find it too empty or unreliable.
