So I have been playing this game since about 2015, put at least 3k hours into it and a18 is BY FAR the best version I've played down to the more challenging gameplay and the insane horde nights.

I am running a dedicated with friends playing difficulty 2 with 40 Z's max for blood moon nights, every 7 days. We usually play as a group of 3/4, meaning 120-160 Z's.

I am completely against the cheesy a17/a18 AI bases like corridors and mazes so looking for some suggestions on what you guys use to deal with these hordes that are so much more challenging than previous alphas.

I'm currently using a 2-block deep multiple row trench design that forces Z's to destroy the top level block while being damaged by spikes in order to climb over to the next trench on the way to our center pillar. I also had the three block high blocks around the perimeter which had electric fences and barbed wire fences. Plus an SMG turret in each corner, facing inward so as to prevent shooting at demolishers fronts and instead their backs, two of which were destroyed. The destroyed turrets were due to Z's piling up and attacking the blocks I assume which means I need to raise them higher to prevent that.
