Wall Breakers...

[size=16]What is Wall Breaker?
This little and fragile skeleton is arguably the hardest troop to use effectively. This is due to the complicated Wall Breaker A.I. and game mechanic. However, Wall Breaker is very important troop to help quickly destroy the Walls leading your army to the middle of the base. Notes that it is the only unit in the game that destroy itself when use (one time use only).


Wall Breaker A.I. & Game Mechanic
How does Wall Breaker choose its target?
It will look for nearest building that is trapped (enclosed by Walls).
It will choose the shortest path, with the least amount of Walls to break through, towards that building and blow up Walls that are in its way.
After the wall is blown up, other Wall Breakers will choose the next building that is still trapped by Walls, run towards it, and blow up Walls that are in its way.
If the path (distance) towards building is too long, it will just run toward the nearest Wall and explode. This explains why sometimes wall breaker target partially enclosed building.
Wall Breaker will ignore “spikes” and other Wall pieces in front of the main Walls.
So Wall Breakers don’t target Walls anymore?
No. Instead of targeting Walls, they aim at the building that is trapped by Walls. However, they don’t attack the building, and just blow up the Walls that are in their path.

Do Wall Breakers favorite junctions?
No. Wall Breakers will run in a straight line towards the nearest building. When it encounters a Wall, it blows it up.
