You guys are all doing too much. This base is all you need:
Rear view:
The spikes at the back are not at all necessary, I was just experimenting. I took the basic concept from a Jawoodle video and customized it pretty heavily. This is the middle form of the base. You can build it on day 2 with wood and that will work nicely for the first 2 horde nights. Upgrade as you go until you can add the traps and eventually get to steel, hopefully before Demos show up. It's a melee/close combat base with turrets for when you need to repair if at all. Most zeds get stuck in the electro fence and you can bash/blast them at your leisure. You will need to shoot spiders and be careful because every once in a great while they will land a perfect jump and come right at you. Maintenance is SUPER minimal...maybe 3 blocks to repair, plus the fences. As long as you don't screw up and trigger the Demos it should be an indefinite cakewalk. You can also make it modular by building a second copy leading out the back of the first as a fallback point. For multiplayer you can make it double sided or even quad for 4 players. Fun, easy, flexible, low on resources and repair time.
If anybody needs more detailed help on building it, let me know.
