The contents of this book are excellent, the traits and equipment make it possible to easily run a Sci-Fi skirmish using the existing Brink of Battle ruleset. However the PDF, as it currently stands, is awful. The terrible backgrounds used for the pages make it somewhat difficult to read and impossible to print. The previous, black on white version, or the layout used in the original BoB rulebook, is much preferable in terms of readability and usefulness.

So while the content is definitely worth checking out if you play Brink of Battle, the design choices make it more difficult to use. I hope that if the designer evolves this into a paid-for product that he makes a more sensible choice when designing the final layout of the book. Coloured backgrounds might look fancy on a screen but a simple black on white layout is preferable in terms of usability.
