Well, my last fort ended in a terrible tragedy, mostly due to hubris and inattentiveness on my part. I'd embarked in a fairly cold climate and the above-ground water was frozen for most of the year. We had ample food stocks and plentiful supplies of ammunition, and I'd managed to set up a small chemical industry. The main problem, however, was that gangers would not infrequently become wounded as a result of skirmishes with pit slaves and redemptionists, and the lack of water meant that even a relatively minor wound was likely to end up fatal. There was a source of water in the caverns, but several forgotten beasts and packs of plague zombies stood between the fort and the water. The plan was to wait and outfit the militia with carapace armour before sending them against the FBs, but when one of my rising stars got wounded, I jumped ahead of schedule with disastrous results.
The initial breach and assault into the caverns actually went fairly well - all the FBs dead with only two casualties. One of them was the Gang Leader, survived by his wife and daughter. His youngest son, formerly a ganger in his father's squad, got shot by a pit slave and died due to dehydration a few years prior. The other was a green ganger who I had just impressed into the service. It was a tightly-knit settlement and the gangers had a lot of friends, so the people were upset by the casualties, but I figured that the benefit of having water for the wounded year-round was worth the deaths of our noble fighters. I was sure that my plan ended in a victory, so I'm certain you can imagine my surprise when I was hit by an ambush notification. You see, a little while earlier there was an ambush by a redemptionist group. Though easily repelled, they did kill my watchdogs, and I happened to forget to chain up some new ones after the fact. Their friends took advantage of this lapse in security to have another go at it.
They were already inside the walls by the time I was notified, and I rapidly scrambled the gangers to repel the threat. The redemptionists had two pistoliers and a flamer along with some flagellants and spearmen. To their credit, the militia made it as quickly as possible, but by then the redemptionists had already set a few people on fire as well as setting the whole settlement ablaze. This alone wasn't enough to cause serious problems, but the relocation of the militia from the caverns to the gate allowed the plague zombies into the fort. They too were dispatched, but the additional deaths from the redemptionists and the zombies were enough to drive everyone over the edge.
I'm sure you know how it goes when that happens; people punching each other, running around babbling, refusing to eat and drink. It got ugly. Some of the gangers went berserk and started shooting, but the forces of order won that fight. By the very end, aside from a bunch of children and civilians, the only person that was in a sound state of mind was a 65-year-old ganger by the name of Rectus. He wasn't even unhappy. When I looked at his preferences, I noted that he absolutely detests redemptionists. At least he had a good reason, now. A few scavvies tried to attack the settlement as it was crumbling but, funnily enough, they managed to screw up even with a lone senior citizen as their only opposition, wandering into the grox pen and getting stampeded to death.
When it was down to just Rectus and a few civvies, I abandoned, letting them go off to start new lives somewhere with less crazy religious types and horrors from the deep.
Here's how it looked a little while before the end.
In the course of all this, I learned that some of the traded schematics are still wonky as hell. I bought some plasma lathe blueprints from the Guilders but they would only unpack into Separator blueprints, so I assume that the trade item is misnamed. Other than that, everything seems to work as intended, though I can think of a few minor improvements. Also, I noticed that the game makes a lot more sense with weather off. Dust storms still happen, but there's no rain or snow that doesn't make sense. I should also do something with the carapace bars that the guilders bring, since at the moment buying them is a trap. Maybe put in a reaction to attempt to turn a few of them into a moulded plate.
