Mutants & Masterminds, or M&M for short, is an adventure roleplaying game in which you, the players, take on the roles of fictional superheroes having thrilling adventures in an imaginary world. One player, the Gamemaster, takes on the job of creating that world and the stories for the other players to take part in. Together, you create your own tales of heroic action and adventure, like your favorite superhero comic books, television shows, or movies. You don’t need any expensive computers or video game systems to take part though. You just need a book, some friends, and plenty of imagination.
