We're up to Day 73 or so on my server.
With zombies set to 75% block damage on horde night, and between 2 and 5 players most of the time, the base is *mostly* indestructible. When I first started playing 7 Days, most of the traps and stuff seemed, if not useless, then not totally worth the effort and resources. Zombies will just plow through it eventually anyways.
Then I came to realize, it's not about stopping the zombies. It's about slowing them down.
So I built the 7 Day base as pictured, surrounded it with a trench, filled the trench with land mines and spikes, then added more land mines and spikes around the outside of the trench. Then I put some spinning blade traps and metal spikes on the inside of the trench.
Works like a charm. Most hordes don't even manage to pierce the steel cladding of the base unless an exploder manages to get close.
It helps that I have 2 or so people regularly feeding me resources. If I had to mine and harvest for all this, between the time it takes to do that, craft it and place it every 7 days, I probably wouldn't be able to keep up with it solo.
About the only failing of the 7 Day hordes at this point is the suboptimal frame rates that still plague this game. Better than it used to be, by a long shot, but horde night never feels "good" after the first couple because you lose enough frames that you don't really feel in control.
Also does anyone know how to pitch down in the Gyrocopter? The internet claims it's your "Crouch" button control key but that seems like bullshit. I've tried that, tried remapping, tried a lot of stuff. It goes "up" just fine, but getting down is an exercise in frustration.
