A simple block invasion wave but has the mechanic similar to that of the Demolition Crew wave where enemies continue to fall when something supporting them below is destroyed (in this case, the destructible barriers). Pecking Order starts from the barrier to the chicken upwards.
My current wave tools don’t currently support this kind of mechanic, but I was able to create a wave (very) loosely inspired by this, so… added in v.110 Idea
Off-topic question, I’m wondering if Klaus can be made to shoot potions on a fixed place at fixed intervals just like how Pesters can be made to shoot periodically? This is for newer waves featuring them, if ever.
