Was expecting more:

I'm new to Unknown Armies and became quickly interested in the setting after reading Book 1 and hearing great things about the system. When I saw this supplement advertising itself as an add-on filled with more information on the world, I bought it thinking it'd give me more NPC's, Schools of Magick, and plot scenarios. While it did contain many blurbs of info (usually in small paragraphs and at most a page), it hardly offered anything mechanical, or more than a handful of ideas to throw into a campaign.

For instance, it tells you a quick paragraph about the existence of Urbanomancers, and Narco-Alchemists, but it doesn't tell you how they work at all. I found most of the info later in the self contained second edition, until I was later told that they were written for the third edition in Book 5.

This disjointed information makes it difficult to run a complete game, and overall I would advise those interested in Unknown Armies to skip book 3. However if you're a veteran to the universe and are willing to make most things from scratch or just want to hear about the latest rumors happening in the modern world. I'd give it a light recommendation.
