The Marching Keep: siege it like a castle.

What it is

A castle of giant ants linked leg to leg. By night it marches across the land and eats every tree, leaf and crop it walks over. A wooden wall is wood to it. By day it digs in. Army ants build nests and bridges out of their own bodies, which is where it comes from.

Where and when it comes

• Only at night. It comes to the meadows and the jungle.
• It marches in from 70 to 90 metres away, straight at you.
• After one is slain, another cannot come for about 40 minutes.

How the fight works

1. Marching. It walks at you, eating crops, trees and wooden walls on the way.
2. Walls. Its walls are solid, and its ants bite anyone who presses against them.
3. Breaching. Knock out a block of wall, and more ants rebuild it. Stand in the gap and they cannot.
4. The queen. Only the queen, in the yard inside, can be killed. Reach her through a breach or over the walls.

When enraged it marches faster and rebuilds its walls quicker. Its walls fall apart into a million ants when the queen dies.

Tips

• Stand in a breach to stop the ants rebuilding it.
• A cannonball makes a hole faster than a few blows.
• Keep your crops and wooden walls away from its path, or it will eat them.
