Chitin wall

A chitin wall is a Vanilla structure made from the chitin material, added in the Vanilla Factions Expanded - Insectoids module.

Strategy
Chitin walls are twice as durable as steel walls and more durable than all stone walls. Chitin walls are also four times less flammable than steel walls. Thus, they may be a viable alternative for perimeter defenses on maps where stone is scarce and plasteel is a luxury.
