I survived the year-or-so long zombie invasion in #dwarffortress. I built traps behind the main gate, then let them in a few at a time, using the military to polish them off. Aftermath recovery is taking months - they were all armed and armoured, plus they massacred a year's worth of visitors. And being zombies they dropped off parts as they fought and died. Just chucking the various dead bits into the lava has kept the whole forst busy for a couple of seasons so far.
Medievalists and Medieval-adjacent. Sort-of.
