Yes, the walls are just repeating ballistas. There are two ballistas in game so that means two walls, if we extend them to the right length then we make a choke point in the middle for Zulus to come through. The animations of the crew cranking the ballista and firing it etc. will be replaced with rifle animations and every time the ballista fires there will be a smoke effect, rifle sound effect and an invisible bolt will come out. The damage for this will be made higher so it seems as if people are getting shot.

Progress with walls

-completed getting walls in game with choke point
-uncompleted getting animations in game (having problems with this)
-uncomplaeted getting smoke
