Awesome! I've been waiting for this to start a new game. I guess I know what I'm doing tomorrow.
Well, the good news is if you already started a game with SCore and NPC Core, then I
believe you can add NPC packs without starting a new game. But I've only tested this briefly, so I can't guarantee it.
It's also good news since I'm updating more NPC packs now. I will do Whisperers, if I can get the improvements done quickly; otherwise I'll do Rogues and Psychos. Not having to start a new game when those come out would be nice.
Sounds awesome!
How do these compare to the baker and the nurse in NPCCore and the hire able raiders?
Nothing major, other than the character models of course.
The spawn probabilities are different (and IMHO far superior) to the other packs. Spawning is staged by biome difficulty (so you won't encounter a rocket launcher NPC in the forest but might in the wasteland). The spawn rates are lower, so they don't overwhelm zombies; you will probably encounter only one or two per day.
Each character supports all the NPC Core weapon types, so there's a lot of variety. (For better or worse, depending upon whether you think a teenager should ever be armed with a rocket launcher.

)
I also tweaked some of the sounds. No new audio clips, but new sounds using the vanilla audio clips, so they're more appropriate and less repetitive.
But other than that, what you see with the Nurse or Baker is basically what you will see with these characters. They have the same dialog options, hiring costs, etc.
I do plan to add "flavor" dialog options with backstory, but that's for a later update, when I know what the backstories are going to be.
