So, after much self re-assurance, I started up the game and decided to take any fate that awaited me. Rush time sound came, then the wailing, and the pitter patter of little Zombie feet. I was doing some organizing during that, checking which weapons I had on me, arranging what was on my hot bar, making more shotgun shells, eating/drinking, etc. About 30 minutes passed before I looked over the edge of the roof of the brick building I was in to see what the horde was. There wasn't much left, some dogs dancing on my fully upgraded Log Spikes, some Ferals, and a few Cops walking in. All the regular Zombies were dead or slow crawlers that were dying on the gauntlet of wood spikes I had placed semi-randomly between randomly placed 2 high 3-4 block wide double upgraded Wood Frames. That defense system extended out from my building 20-30 blocks on all sides.
An hour or 2 into the horde it had become a trickle, 1 Zombie every few seconds would rush into the gauntlet, dying or making it to the building depending on what type they were. Things were going so well I mainly just shot at them with the crossbow, even though I was so far away I was only getting body shots, the spikes eventually killed them anyway. Used the Sniper Rifle a few times on Cops, but had limited Ammo as I only can make Shotgun Shells, still haven't found the book to make Bullet Tips.
2-3 hours in I got too close to the edge and fell a couple floors down onto some Wood Frames I had placed around my building to deal with the 14 Day Horde(a day that lives in infamy). That broke my leg, but I made a splint and got back to the roof. At that point I decided just to stay on the roof and wait out the last few hours. I could hear 2-3 Zombies pounding on some blocks in my building, other Zombies continued trickling in but were dying from the spikes. I was content to just wait for daybreak and clean the last few out.
Morning comes, I get off the roof onto the floor below and I look down the mostly destroyed(previous Hordes) stairway all the way to the ground floor. There are a couple dogs, 4 Ferals which were crawlers, and a few regular crawling Zombies that entered once in awhile. The dogs were killed with 6 Shotgun blasts, 1 of the Ferals also died from the shotgun at that distance. The rest slowly pathed their way up the stairs and I took them out one by one. Then I heard a Witch enter, so I stopped looking down the hole waiting for her to path up the stairs, which never happened as she wandered around the floor below and got stuck or something. So I went down there, found her and shotgunned her to the face before she could call in a horde. Finally, it was all over or I thought.
I go down stairs to survey the damage and it was pretty light. A couple foundation cement blocks, a brick block, and 6ish floor wood blocks were destroyed. Exited through the hole they made and looked around and things looked pretty good, I could hear this constant pounding on something in the distance though and occasionally a regular Zombie would come trickling in on the same path the Horde had used, it was very steady though, as if they were part of the Horde. I got outside my perimeter and as I did I began to isolate where that pounding sound was coming from, it was the house next to my building, but 70-80 blocks away from it. I went over to investigate it. As I drew near I could hear a flurry of activity going on inside and suddenly blocks were breaking, Cops were charging up vomit, and bees began swooping in. Over the next couple hours a whole Horde streamed out of there. Cops, Ferals, Spiders, Bees, Dogs, I even saw a bear in town which never happens(desert town) and I just stayed away from the bear which eventually despawned.
So most of the rest of the day was dealing with that. Most damage was from dog bites and Cop puke. Managed to loot the ferals/cops which was nice.
It dawns on me that if this Horde had not spawned in that house, I could have been totally screwed. It didn't though, so, whatevs.
td;dr I survived!
