It can be daunting - as an In Nomine Game Master, you must create the world, the setting, the plots, the people... you not only play God, but Lucifer and all the other Superiors, Archangels and Demon Princes alike. The Game Master's Guide 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 alike, the Game Master's Guide reveals the inner workings of the universe, how you can change them, and why you might want to do so.
