The Gamemaster's Guide has everything a Mutants & Masterminds GM needs,
from guidelines on creating challenges and adventures to advice on
designing your own setting and series. It includes guidance on how to
set up and run your game and to help your players create the best
heroes, archetypes that make building villains easy, world building
tips, and options for modifying the game to suit your group's play
style. This new Revised Edition of the original book is a handsome
hardback that adds two adventures, new villain archetypes and minions,
and more. The Mutants & Masterminds Gamemaster's Guide is a must-have
resource for new and experienced GMs alike, and the ideal companion
volume to the Basic Hero's Handbook or Deluxe Hero's Handbook.
