This is a dark book so be warned. If that is what you came looking for you've found it. This book understands the cornerstones of dark horror from past horror fiction like Clike Barker and grasps the newer grue of Japanese horror. I hate to compare games but I do when I feel it is a compliment...This book conjures that creeping unease that Kult had from back in the day. Horror that does not negotiate, creatures that can't be killed with the silver bullet and fates worse than mere death. The monsters are very modern and original. This version uses the Gumshoe system for stats (but there is a d20 version available) making it used for Fear Itself but compatible with The Esoterrorists and Trail of Cthulhu. If you fiddled with it you could use it for a grittier profiler/psychokiller Mutant City Blues game but I imagine you would have to excise/alter the supernatural aspects. On that note you could adapt this book to other horror games to give them more of a backbone (or rip it out if you get the meaning). The writing is very good. Often as short stories or interviews that give a glimpse at the horror behind the black curtain. Art is also very well done and distinctly disturbing. I liked the layout of the book and found the information easy to access in play. Just under $15 you get your money's worth. Just remember this product is for a mature GM and presents a very dark unflinching take on horror roleplaying. But if you are tired of buying horror creature collections to just end up with topless succubi or uber kewl lycans then take the leap...just don't say you weren't warned.
