Oh nice, that does sound fun -- I'd definitely enjoy seeing that if you wanted to post. I wouldn't go so heavy on the traps to make things more interesting, but building with blocks gets to me sometimes, I am not used to it... so more creative builds I havent gotten used to. I really need to go into a creative game and practice or watch some streams such as yours lol. I'll keep an eye out or just go to your Twitch page.
And Nighty.. I built and defended that base on Warrior difficulty with jacked up spawning, and the only guns I used on my hotbar were my pistol and the magnum on a spider that jumped onto my bars.
I built a similar design, just a bit bigger with more spikes and 3 layers of walls on Survivalist (1 step below insane) with even MORE jacked up spawn on bloodmoon and the last horde night survived at day 49. So, I don't know what you're rambling about. The other design was a mix of concrete, cobblestone and iron blocks. By far not a bunker. Survived every blood moon. I put one concrete wall around a crushed-car encampment and survived 8 blood moons in it.
Either you're standing there watching the zombies beat your bases up and not combating them, or relying on walls alone. Both worked on insane difficulty with 64 zombie spawns (including a modded XML guppy made giving constant spawning), but that won't work in 17. Adapt - improvise - overcome. Not "Well guess ill do what I did before and die now."
And the AI goes for the weakest point? Okay so dont make a weak point. Look at my screenshots, clearly it's a cobble stone wall with spikes around it. All 4 sides were hit. 4 screens, 4 sides of the base. They revert for going to you if theres no weak spots. And if they do go for weak spots, you can't think "hey they're going for weak spots, and I have put weak spots in, I should either not have weak spots or know to combat them there"
