'World of Darknes: Mirrors' was an exciting title. Basically, it gave you all of the tools to disassemble the nWoD and refashion it in the image that best suited your gaming group. It gave a wide variety of genres, new rules and some alternative character creation rules. 'Bleeding Edge' represents one of the chapters that didn't make it into this book, and the modular format of these extra chapters does represent good value. The reason I say this is that with any compilation of alternate settings and rules, your value will be determined by how much you actually use. In this way, you are able to select from the extra chapters what material you want to pay for.
That said, 'Bleeding Edge' is a remarkably ambitious piece of work. It seeks, in 23 pages, to cover the cyberpunk genre and integrate it into the WoD - no mean feat. Overall, it gives good background information about the genre (which I think all Shadowrun and Cyberpunk GMs should have to read) and sets the tone as to why this would be a good fit for White Wolf's setting.
It offers some additional backgrounds that are contextualised to this genre, none of which are game breaking and they all add their own machine-oil and chrome flavour to the game. The archetypes are well-presented and would be a great starting point for a new gamer, someone not familiar with the genre, or an ST looking for some good NPC starters.
However, where the product falls down is in what could have been included (but what not). Whilst cyberware does form an integral part of any cyberpunk setting, it is glossed over with minimal rules. The overall writing is very brief, as demanded by the breadth of scope and the space dedicated to making it happen. What I would have liked is a supplement about twice this size, where the author would be allowed to take their time and explore some of the concepts a bit more.
As a starting point, this is very good. It sets the tone and provides enough of the basic tools that an enterprising Storyteller could fill in all of the white space and make a really good game. And that is the caveat here - pick it up certainly (and you'll enjoy it), but expect to be doing some additional work to make this a viable additional to your game.
