Defensive Wall Spikes

Defensive Wall Spikes can be placed on defensive walls to increases the wall strength by 45%. The cost of building this is linked to the length of the wall section it is placed on. Cannot be built over Defensive Wall Gates.

Gameplay
Defensive Wall Spikes cannot be placed on single or double doors of defensive walls. Defensive Wall Spikes do not cause damage to enemies when they are attacking a wall. It is possible that Defensive Wall Spikes can prevent cannibals from climbing the wall, though this isn't confirmed. Once built they have a small collision box which provides a sort of buffer that prevents cannibals from hitting walls, though this isn't true for mutants, however, the cannibals may jump on top of the spikes or glitch through and still hit the walls. Fast cannibals can jump on top of spikes and may leap over walls. Mounting decorations on the wall behind the spikes may prevent this. Defensive Wall Spikes are generally expensive and best only build on key sections of walls you cannot defend yourself.

Building
Cost is dependent on the size of the defensive wall. The cost is calculated as follows:

Stick Count = (Wall length in logs * 2), Rock Count = (Wall length in logs * 3)
