Killing Time in the New Shadows: 11 New Classes for Modern Adventurers (2005)

From publisher blurb:

Tired of standing alone against the forces of nightmarish evil? Then it's time to beef up your weary band of nocturnal adventurers with some brand new character classes! We have five Advanced Classes and six Prestige Classes for your characters to grow into, each one carefully tested for game balance. All of them are types of heroes (or villains) that you have seen in the movies and read about in paperbacks, but that the core rules don't quite cover. All eleven have some connection to the supernatural, and all are better suited to settings like "Urban Arcana" then they are to purely realistic games. These are occultists, mad scientists, avengers of the night and stalkers in the shadows, not Army Rangers or Navy SEALS.

So buckle on your chainsaw, whisper a few words over your sacred relic, load up the shotgun with silver slugs and go toe to toe with the hordes of darkness tonight!
