well before everyone yells at me for how stupid this idea is, you have to understand I dont know anything about modding so I dont know whats possible but here it goes.
Troops can be placed on walls and on ground, while artilley can only be placed on ground right? Is it possible to alter the code of the tower/wall/plateau that uses the ground data on the wall? example: use the road data on the wall since the wall walkway is hard coded? possible or am I just stupid?
