Best wall defense setup?

[thetoolcrafter]

I am planning on making a world with loads of enemy bases (very high etc. on the world gen screen). However, i dont know a good wall defence i could use against them. How should i make an amazing wall defense? obviously 2 walls and some turrets wont be enough

[kinnom]

apparently a gun + flamethrower combo is quite effective

Current state of the art defence is to use construction bots to repair and replace anything the biters damage or destroy working from a standalone network covering a section of wall.

They can then be supplied by a train that runs round dropping off supplies loaded at the main base.

If your base can provide the materials, a minefield managed by robots can stop most biter attacks short of behemoths before they reach your walls... behemoths just walk right through it though...

Walls? Let me tell you about my walls Sir!



This screenshot shows my walls, with me holding the blueprint in front of it. When using the blueprint, I overlap the flamethrower at the end to line things up.
The walls go all around my base. There is a combination of lasers, turrets and flamethrowers. The latter are spaced so that their flames overlap.
There are two transporter belts, one for bullet-clips and other small stuff, the other to transport ores to my storages.
There is a bullet-chest in between the turrets. The purple inserter is connected to that chest with a red wire and stops after taking 30 clips from the belt.
A green wire is running from pole to pole and connects to each bullet-chest and also to the feeder of the clips. (Top right, red inserter). It makes sure all chests combined have a certain amount of clips.
Clips that weren't picked up from the belt go a full round and are put back in the storage chest, ready to be distributed when necessary.

Nothing gets through these defenses. They do require some repair every now and then though.
Hope that helps.
If I can figure out how to post a blueprint, I will.

Thank you so much! I will definitely be using this setup

Thanks man. I was already using that mod, but somehow didn't realize I could just post the content of the txt files here.

That's my central base defense =>

Hi guys first time I post here. After my third start in Factorio with a big factory after 20 hours of gameplay, I was curious about other defensive designs because I like the sort of castle-builder feeling. Well, there are some, but not a lot of wall designs out there after googling, thus I found this thread.

I wanted to have this "heavily guarded thick border" feeling, so I put some aesthetical effort into my two designs. The one chest in the designs is a requester chest for 100 piercing rounds ammo. The range of the laser turrets barely overlap from one post to the other one. So if biters come, they allways get aggroed to one guarding post, and no area in front of the wall is uncovered. I can walk a few meter in front of my wall without taking any attacks from the bugs. The repeating pattern is laid out, so that the logistic network of the roboports allways touch and so every part of the wall is repaired if the bugs manage to come close.

I'm not absolutely satisfied with the design, because the flamethrower turret should be installed a few more meter behind the laser and gun turrets imho for saving that precious oil and environment. =)

First wall design "eco friendly" =)
