I have the book. All the fluff pretty much states that the zombies and werewolves are made with super since. No magic so far.
Maybe its just the werewolves and vampires, but I don't see those as anything but fantasy unfortunately.
Saying that, maybe its just the way which I'm seeing it presented. If the game's aesthetic was more gritty dieselpunk maybe I'd be more into letting that stuff slide like with Vampire or Shadowrun. From what I'm seeing the game's fairly pulpy, to the point some goblins in trench coats wouldn't go amiss, but they're trying to present it a as a bit harder a setting in their marketing oddly.
...Though that's personal tastes. I do cover all my minis in a layer of grime.
