Yeah it would work as a mod. I was just suggesting in general.
I’d just give them all or most if not all of the tree (good and bad), though genetically unstable can be as easily a game ender as a game runner.
If you really wanted a good idea of what you’d need to add trait wise, just make a new character and spawn a bunch of a specific serum and a syringe, and dope up until you feel like you’ve gotten enough traits for the scenario. Then write them down and make that what you get.
I’d just, go through the tree and add most of them, then give them like, infection and give high mutagen withdrawal, start them off in their jimmies and a subject suit with nothing but a makeshift knife and their new friend/(distraction?) by their side, crawling out of a burning wrecked unmarked cargo van full of various research materials and corpses splattered everywhere, possibly also surrounded by whatever the cargo truck crashed into.
You’d have the mutant scenario trait choice, though it’d be cool if someone could add to the source a flag that greyed out traits that would cancel or counteracted with the traits your profession started with. That way you can pick genetically unstable if you want.
It’d be nice if the scenario started at midnight and as close to the actual lore day of the cataclysm as possible. If not, I’d probably force world to start at night anyways because I like sneaking around.
4-6 points cost?
