I certainly don't like the demolishers - spike proof and explody is bad enough but do I understand correctly that they do excess block damage with their regular attacks as well? Gah. Hopefully their just a short term place holder for a more balanced base threat. Having said that, I know from watching and reading that there are at least 4 viable anti Demolisher horde ideas with varying degrees of cheese.
I've seen the stairway-walkway-drop in front of a tower you shoot from, which is an exploit - but seems safest.
I've seen the downward slope into a tunnel with upper and lower blade traps, where you turn the uppers off for demolishers, with electric fences and barber dire to hold em while they get chopped.
I've seen the half block step under a 3 tile high blade trap that prods the Demo and Biker heads up where they get hit, but not shorter zombies.
I've seen the turrets behind where the zeds enter so they shoot them in the back.
I've also seen players not try to kill the horde, but with bases designed to hold 'em off, with either open and shut doors to let small groups in - to isolate and kill the demolishers when they show - or running / driving between places as they get broke.
Seems like a good few different options, only one of which constitutes an exploit, and only one of which is 'gamey'.
AM I right in my understanding, or am I missing something?
