This is a monster of art. It is pure art, and at the same time a highly playable scenario, or rather, campaign. It is superbly written, illustrated and presented. I have played most of the great old ones; Masks, Fungi, Azathoth, The Orient Express. They cannot compare to this behemoth. Even as a GM, I get to experience the horror I am about to unleash on my players, because the book also gives me a kaleidoscopic view of the world behind the stage. At times I forget this is fiction. It is the best gaming material I have ever touched, and brings Call of Cthulhu, that I played for the first time in 1987, into a contemporary and frankly even more sickening future. I strongly suggest you buy this, and should you like to use it for another rule set, it works well everywhere. The stage is set, and madness knows no bounds.
