Boulder Wall

Boulder Walls are a unique type of "wall", featured in Age of Mythology. They can be found at the Scenario Editor, as well as in some campaign missions.

Overview
Boulder Walls are extremelly tough walls, even against siege weapons, such as Petroboli, as they combine enormous hitpoints with very large resistances.

Unlike the Wall of Troy and the Wall of Atlantis, however, they are not invulnerable and can be attacked. Still, it usually takes much effort to demolish them, and even more if there are no siege weapons nearby.

As mentioned, they are featured in some missions, usually to deny passage to the player, but in one case, they are entirely decorative; in the mission War of the Titans, four Boulder Walls clamped together represent the site from where Gaia will emerge to defeat her son, Kronos.

History
''This pile of rocks is not natural. The huge stones were moved by giants - or by men at tremendous effort - to block unwanted passage.''
