The Town Walls Objects Set provides a lot of (modular) object tiles to create your own medieval city walls and medieval/17th-century city centers.
These new object tiles can be used to give a medieval/17th-century feel to your game.
The walls have been coded in such a way that they can be placed on water, so also on rivers/canals to create a moat around them.
There are also overlapping/drive-through tiles included, so your vehicles can enter the old town
