Great stuff here to add to an existing campaign setting.
I will go on record as stating I am not a fan of adding the fantasy elements to my modern horror game, but I do enjoy reading the take that Aegis Studios puts on them. So while I do not use them, I do enjoy a good read through them.
The edition of new races, a focus on angels and demons, a few agencies to utilize, new classes, new spells, and new feats make this a must have. I was luckily enough to get a hold of this just before our game started and my players were happy to see it. It really helped flesh out a few of the choices they were struggling with.
I also love the burn system for non-divine magic used by humans. It has made for an interesting character that is a little too smart for their own good, but not wise enough to know it yet. ;-}
Thanls for another great product!
