Interface Zero is the goto book for cyberpunk savagery. It has detailed history, equipment, characters, and setting information for this dystopian future. The authors do an excellent job of drawing you into the setting with a writing style that's engaging and informative. The system does a great job of shoehorning cyber into Savage Worlds via a method that is clean and elegant.

The only negative I have is the amount of history presented up front. It's great stuff but it took a while to get through.
