The fun continues.
I've got two 3x3 staircases going down into my fort. One of them I sealed with 9 obsidian hatches, while I shut off the other one by putting down a pillar with a door on each side by the bottom of the staircase.
Suddenly I get this message, which I've never gotten before:
Butcher's shop toppled!What on earth? I head over there, and the shop is just gone. I grab a screenshot and wonder if I should head over to the forums and search for answers, when all of a sudden:
Door destroyedDoor destroyed (paraphrased)
Now it dawns on me what I'm facing here, buildingdestroyers. I've got a small military of two people up (not knowing what class of weapon a "steel ripper" or whatever they're called is, I don't know if they're armed with them), and two war dogs trained, and I send them over to see what's going on, and end up fighting a large radscorpion, three supermutant thieves, and some other creature I don't remember the name of. Ended up activating my entire vault (14 people after an immigrant wave) into one single squad, and they beat the intruders to death.
After the kobolds of vanilla Dwarf Fortress, this is some challenge
. Just the fact that they break down doors and hatches, so that I don't feel like a cheater when I build and lock them, makes this so awesome.
Edit: looking at the unit's list, turns out it was only four supermutants. I must've been looking at clothes or something when I saw the "radscorpion" line.
Edit 2: just got another eye bot, and realized that was the last creature, the one I forgot about.
