As an In Nomine game master, you not only play God, but Lucifer and all the other Superiors . . . Here's the book that will help you do all that, as well as:

* Choose how light or dark, gray or stark your campaign is.
* Fit real-world religion into your In Nomine universe.
* Discover the extent -- and limitations -- of the power of Superiors, and how to handle confrontations with them.
* Pick alternate rules that strengthen or weaken humanity, celestials, and ethereals.
* Tailor your game to be as serious, satirical, or downright silly as you want it to be!

An invaluable In Nomine resource for inexperienced GMs and old hands both, the Game Master's Guide reveals the inner workings of the universe. (And players might like to sneak a peek at it too!)
