Games Workshop Warhammer 40k - Codex V.9 Orks (En)

The codex is chock full of rules and has just about the right amount of background information on the Orks and the various aspects of their faction/unit choices. To be honest, they probably wouldn't have been able to fit any more background stuff in because there are so many rules sections in this book for different types of game/setup etc that it would have been overload but the codex does its job nicely enough.If you're an Orks player than you're not going to be disappointed at the level of detail in here.
