to clarify what this book is.

they put World of Darkness on the cover to increase sales, but it is a Source Book to Hunter the Vigil. this book is about making serial killers in Hunter the Vigil, and what cells, compact, and conspricacies have Slashers in their group.

this book is not for the feint of heart (any of the WoD/CofD books aren't frankly) as it dives deep into the pyschology and mindset of a serial killer. its very interesting and complex. from your typical masked murderers, to the charismatic killers with calling cards, and so on.

the reason this book is a source book for hunters, is that at some point, hunters go insane. they see horrors that only their group can understand, and what happens when their convictions are shattered? what if they start questioning humanity and start culling them to prevent vampires to feed on them? so many role playing possibilities.

as of this writing, you can only get this source book seperately, however, the 2nd edition of Hunter the Vigil will have this book, so if you want to wait, there you go, if you want to use this book for your Hunter game have at it!
