Nope. Even my experimental which is nearly a month old has some pretty brutal swarms.
Although I don’t know if it an increased spawn rate, or simply a massive number of initial creatures.
[Edit] Because double-posting is bad mmmkay.
Day 20 of summer. Crops still haven’t grown, and my strawberry/blueberry plantation hasn’t even sprouted!
In the past 10 days I have finished my Meth-Lab-turned-crafting-station, and fixed up my scooter-turned-bicycle. After spending an entire day playing with a remote-controlled car (what do you mean it doesn’t give a morale boost?), and another day painting part of one wall of my house blue, I decided to go exploring.
Found a stash underneath an evac shelter, and a survivors map. Took note of the gun stores on the map, and left a note on a cash card, with a pot thanking the nice person who made that map. Yay! Found a gun store which was on the edge of a tiny town.
On Day 20 I picked up 21 aspics, some light survival gear, and traveled down on my bicycle to the gun store. Couldn’t find a way around the hordes (which completely covered the town), so decided to make a pit ring in order to hold the zombies off.
Kept on getting raided by zombies while creating my pit fort. And when it turned out that zombie necromancers can raise pulped corpses, for example a pulped shocker brute, I decided to get the hell out of dodge, and that is where I am now. Fleeing for my life. I will probably drive for about 3 hours to a small town that is thankfully free of zombies (I already cleared it out), and reinforce that place so I can fight the zombies on my terms. Zombie hordes are fast, as I found out in one of my previous playthroughs, so I probably won’t have much time. But if I do, then I will take it happily!
Thank goodness for caffeine pills! [/Edit]
