Gatekeeper [Tournament Wiki]

Gatekeepers have specialized in combat within the anthill.

Due to their morphology they are able to block the tunnels with their body slowing down the advance of possible invaders.
On the contrary they become very awkward when moving outside the anthill and therefore can not be used to attack rows or colonies.

* This caste can improve its defense by building "Ventilation Tunnel".
