The Fortification Wall is an advanced defensive wall that blocks most Tech 1 & Tech 2 units and low-altitude projectiles. Advanced walls have almost four times the health of a basic Dragon’s Teeth, and will take quite a beating before they break.

Use them to absorb enemy fire, or to block a path.

They can also be used to help protect Cacophany, and especially Bastion towers, both of which can fire over them. High-trajectory artillery can also safely shoot from behind walls.

They are great when used against Alien Raptors and Scavengers!

Walls resist crushing by heavy T2 units, but some massive T3 will plow right through them.
