Building Walls
To place a line of wall, click and hold the left mouse button, drag out the wall and then release the mouse button to construct the wall. You can “layer” your walls by clicking and dragging a second wall adjacent to the first. There’s no limit to how thick your walls can get if you have enough stone.
When placing walls, if any piece of the wall is not in a valid building location, the invalid section(s) will turn red.
In order for your troops to access the walls or towers, stairs must be attached to a section of wall.
Units standing on walls gain a range bonus and the wall they are standing on will also absorb a proportion of the arrows fired at them. Walls also have braziers built into them allowing archers to shoot flaming arrows at gunpowder trails and gunpowder stashes.
