This is the repository for information, house rules, etc., about my Mutants and Masterminds Third Edition (or MM3 for short) games. I'm not a big fan of the earlier editions, but for me, MM3 is arguably the single best general "supers" RPG that exists.
This is a PDF summarizing the two biggest additions to the game: lethal damage and the Inspiration skill.
