Use Scalable City Wall tiles.
| Movement | Fortified City Walls are normally considered impassable terrain for all units, unless siege rules are in effect, as noted in the scenario special rules. When siege rules are in effect, the attacking foot units have scaling ladders, and fortified city walls are treated as scalable walls. |
| Battle | No battle possible unless siege rules are in effect for the scenario. |
| Close Combat | |
| Range Combat | |
| Line of Sight | A fortified city wall hex blocks line of sight to units behind the fortified city wall hex and vice versa. |
