Besiege is a physics based building game in which you construct
medieval siege engines and lay waste to immense fortresses and peaceful hamlets.
Build a machine which can crush windmills, wipe out battalions of brave soldiers and transport valuable resources,
defending your creation against cannons, archers and whatever else the desperate enemies have at their disposal.

Create a trundling behemoth, or take clumsily to the skies, and cause carnage in fully destructible environments.
Ultimately, you must conquer every Kingdom by crippling their castles and annihilating
their men and livestock, in as creative or clinical a manner as possible!
