What would make this mode even more awesome is if anyone infected by the zombies died, then their corpse would come back as an infected. Could this be done though...
but it might cause "infection spirals" where one guy gets bitten and dies, become a zombie and bites 3 others, then they die and so on and so on
Oh, people used to complain about tantrum spirals- but now, they don't seem so bad compared to these things! Must build all hospital beds in small rooms, then WALL IN THE INFECTED once they're brought in! The fortress of the damned! Tomb of the undead! Catacomb of the forbidden doors! BWAHAHAHAHAHAHAA!
So! My last fortress succumbed to a siege because my dw- survivors wouldn't stay put in the Military settlement I designated for them to stay in while they were idled (aquifer, didn't have time to take out the aquifer, no underground safety -ahem, a bunker-, no rock, no mechanisms, no traps- just an unfinished wood wall) and they kept running back to the starting location when they were thirsty. Hate aquifers and slow miners.
Having wanted to try again on a location I may actually have a chance, I've embarked on a double mountain, double temperate freshwater swamp location, Untamed wild, Terrifying, untamed wild, haunted, chasm/bottomless pit, river, underground river, HFS location, with 16 pages of creatures, and 15.5 of those filled with skeletal: infected, antmen, giant bats, ratmen, giant rats, giant olms, giant moles, infected torsos, giant cave swallow, naked mole dogs, trogdolytes, and lizardmen. But three of the skeletal lizardmen started out dead, which is very nice.
I think I've got a better shot now. Let's get cracking! Onward, Shankplunge the Riddle of Ghouls, into tomes of time and engravings across time and space! Never stop digging!
