>Have you read Hunters Hunted II, by any chance? How is it?
I have, and it's pretty damn good, actually. One of the best V20 books in my opinion.
They go into quite a bit of detail on many various mortal groups of Hunters, including ones associated with major mortal religions.
Knights of St. George: Christianity (though it's become more inclusive in later years)
Akritai: Eastern Orthodox Church
Ikhwan al-Safa: Islam
The Judges: Judaism
There's also the U.S. Government, the Society of Leopold, the Arcanum, the Young Bloods (a gang of biker ghouls that figured out a way to keep themselves continually and safely fed with vamp blood without having to worry about the blood bond), major Criminal organisations (the Tong, the Mafia, the Russians, etc.) and more.
The Numina (psychic powers and hedge magic) are pretty balanced as well, with all of them feeling powerful in terms of mortals, but being weaker in nearly every aspect when compared to Vampiric Disciplines, especially in regards to the fact that they cost willpower to use and often have detrimental side effects or bigger requirements.
It also goes into detail on how the Hunters are coping in the new V20 timeline that moves away from the whole "GEHENNA HAPPENS IN 2004!"-crap, touching on stuff like the conflict in the Middle-East and whatnot.
The only thing that bothered me was the way the Numina are ordered; not every Numina is listed under the Numina section, and instead appear get listed under other sections of the book. Like, the "Alchemy" Numina is listed under the faction of the Arcanum, rather than with all the other Numina.
But that's a minor issue, and I highly recommend picking the book up if you got the inclination to play as (more or less) regular mortals against vastly overpowered foes.
