The Bramble Fence is a defensive structure, a fast-growing species of plant, that can be used as a barrier to keep your foes from getting at parts of your base. They have 250 health points (500 when upgraded, but 1000 at CC when upgraded) and regenerate health. Each seperate plant costs 5 coal and 0 electricity to build. Due to their large roots, digging creatures can not go underneath them.Henchmen or creatures that attack it take damage, unless they have the Barrier Destroyability. Creatures with ranged or artillary attacks will also not take damage when attacking a Fence. The Bramble Fences are found first in mission 5.
