Hidden Wall Trap

Description
A wall that is hidden underground. The Wall raises up when enemy units approach, blocking their path.

Usage
The hidden wall trap is the same size as a normal wall, but with approximately 65% of their HP. They remain hidden unless an enemy unit enters a one tile radius around them. After it has activated, the wall will suddenly spring out from the ground, and all units within a one tile radius will be momentarily confused, and have to redecide their targets. A unit placed on top of a hidden wall trap will be lifted up to wall height. This can be useful for slowing down enemy advances, or forcing them to enter a the town with a different route. The short stun is also helpful for low rate of fire defences to get another shot in before destruction. They can even simply be used as a substitute for normal walls if you don’t have enough of them to complete your design.
