Osta Medieval Machines Builder PC

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.
