Absolutely fantastic addition to Mirrors. Those complaining about its lack of content don't seem to understand what this actually was - this is cut material (fleshed out a bit) from a storyteller's book for reworking the World of Darkness as you see fit. It is not supposed to be a full cyberpunk supplement. Judging it for what it was meant to be, it's a fantastic collections of ideas, thematic rule hacks, and advise for storytellers.
[5 of 5 Stars!]
