. The game system is designed to allow players to create virtually any type of hero or villain desired.


In the late 1990s, Steve Kenson had an idea for a superhero setting that he had been contracted to produce. Through a series of misfortunes, the project fell through and he was left with a partially completed manuscript. Shopping it around to various publishers, none were interested (superhero games had lost their popularity) until he talked to Chris Pramas (President of Green Ronin Publishing) about the setting.

Chris made the offer to publish the setting if Steve would also create a superhero game system based on the d20 System. Steve agreed and got to work. Over time, it became clear to him that the game would need to be released only under the Open Game License. Releasing the game under the d20 Standard Trademark License, as originally planned, would have prohibited the inclusion of ability generation and character advancement rules. Presenting a complete game was seen as taking precedence over having a d20 logo on the product, so the decision was made to use the OGL without the d20 license.

Mutants & Masterminds was published in 2002 and the setting, which was once known as Century City, became Freedom City and was published in 2003. The first edition M&M books featured artwork by the design studio Super Unicorn, but other firms provide the artwork on all subsequent releases.

On May 12, 2010, Green Ronin Publishing announced a third edition of the superhero roleplaying game would debut in the fall. This announcement came just 9 days after the publisher announced that it would debut a new DC Adventures game in August, based upon the Mutants & Masterminds game. According to Green Ronin President Chris Pramas, the two new games will "share a common ruleset."

, however it is a highly modified version of that basic system. The largest differences pertain to character creation, injury and damage, and hit points, as well as the addition of Hero Points and, obviously, super powers. There are also numerous other differences such as the elimination of character classes and attacks of opportunity, a modified Skill list, a very different Feat selection, and the fact that any equipment possessed is considered a part of the character and purchased in a manner similar to powers.

The following information details what makes M&M notable among other d20-based RPGs and is provided under what Green Ronin considers "open game content".

Power Level

M&M characters are not class-based nor do they technically have class levels. Instead, they have a Power Level (or "PL"), and typically a character begins at Power Level 10 instead of Level 1. This allows a character to begin as an already established superhero with incredible abilities. The power level represents the maximum rank of any combat abilities a character can purchase. Each power level typically grants a character an allotment of points to purchase attribute levels, base attack and defense bonuses, saving throws, feats, skill ranks and super powers, though the game encourages Game Masters to modify the number of points given per level up or down to reflect the style of game they wish to run. It is worth noting that all aspects of the character from Abilities, to Feats, Skills, Powers, and Equipment are purchased from this pool of points.

The M&M power level does not exactly reflect the typical abilities of another character of equal level in another d20 game, meaning a level 10 M&M character could be much more powerful than a 10th level character in Dungeons and Dragons or d20 Modern
D20 Modern

 for example; it merely restricts the maximum bonus held by skill ranks, ability scores, and most feats and powers. The maximum skill rank is Power Level+5, two points higher than in standard d20 games. With Game Master approval, characters can "trade in" maximum attack in return for maximum save DC/damage bonus, or maximum defense bonus in return for maximum Toughness save. (For example, a PL10 character could have a maximum attack bonus of +12, but could only have a maximum damage bonus of +8.) Beyond limiting bonuses, Power Level does nothing to restrict a character's power; a power level 10 character can have a maximum Strength of 40, whereas normal d20 characters would be lucky to have a single 20-rated score at 10th level.

M&M has optional rules of eliminating the Power Level entirely, where characters have no limit caps to things such as Skill Ranks or Attack Bonuses. They are essentially limited only to the number of Power Points the Game Master gives them, although this may make characters unbalanced. Some d20 System players who believe classes and levels are too restrictive have looked to the structure of M&M for making their own classless and level-less d20 games.

Damage Saves

Damage in M&M is handled differently as well. M&M does not use Hit Points. Instead, a character has a fourth Saving Throw called the Toughness Save ("Damage Save" in the previous edition) which is based on their Constitution score (just like Fortitude). Weapons and powers that do lethal and subdual damage do not roll any dice to determine damage. Instead, damaging attacks are ranked based upon their overall power. For example, a fairly fit but normal human may throw a punch that inflicts +1N (non-lethal) damage, while the irradiated simian mastermind with enhanced strength and razor-sharp claws throws out +12L (lethal) damage. When a character is struck by an attack, they roll a Toughness Save against a target number equal to the rank of the attack plus 15. Success allows the character to shrug off the attack with minimal effect, while failure results in injury according to the degree of failure and the type of damage. Accumulated damage applies a penalty to further saves, increasing the chances of any given attack taking the character down.

This system of damage is meant to model the nature of super-hero comics, in which many characters can ignore most damage outright, while still being susceptible to a lucky punch or super-mega-cosmic blast. For those more comfortable with the traditional hit point system, the Mastermind's Manual rulebook includes notes for conversion to that mechanic.


In M&M, characters are awarded Power Points (similar to experience points) that can do many beneficial things for the character. As described above, Power Points (abbreviated pp.) are used to purchase powers, feats, skills, abilities, and devices. The specific nature of Power Points was changed drastically with the 2nd edition (2e) of Mutants & Masterminds. In the first edition, when a character accrues 15 pp, they advance a Power Level, thus raising the caps on power and skill ranks, as well as on power bonus stacking. There were options to keep the Power Level the same while increasing total number of points (and many sample antagonists in the Game Master setting have more points than their Power Level would suggest), but these have been incorporated into the 2nd edition rules.

Under the second edition, Power Points and Power Levels are independent, the latter being set by the Game Master as a function of the campaign. The 2e concept of Power Level determines only the maximum bonus that any power can give, and does not imply that a character does or does not have the points required to purchase enough levels in any power to reach this limit. Though the two are described as being entirely independent, the Mutants & Masterminds manual recommends that the Power Level be increased by one with each 15 Power Points awarded.

Hero Points

Like many other super-hero role-playing games, M&M uses "Hero Points". Hero Points allow an unlucky player to be able to hold their own in a battle, thus reducing the amount that luck plays into the gameplay. A Hero Point can do several things, like allow the reroll of a failed roll of any sort at a crucial moment, including Toughness saves to avoid damage. On this reroll numbers under 11 have ten added to them, resulting in a range of 11-20, and a very slim chance of failing.

A player may also use a Hero Point to ignore fatigue. This last is particularly useful since, by fatiguing himself, a character can gain any Feat temporarily, or use a Power he possesses to duplicate another power of the same cost. Normally, as stated, this fatigues the character meaning it can only be used once or twice, but with Hero Points to ignore the fatigue, it can be used as long as the Hero Points hold out.

Hero Points are generally awarded to a player by the Game Master when something bad befalls the character, such as the villain escaping without them having a chance of stopping him. This is particularly encouraged if the bad thing in question is something related to one of their disadvantages, and many disadvantages provide no other benefit aside from acting as a source of Hero Points.

 setting. The 1st edition book has pregenerated characters which players can use in the adventure, but those characters are associated with another M&M setting, META-4. Despite this, Freedom City and META-4 are officially separate and their worlds and characters do not intersect.

Settings published for the game include:
Autumn Arbor: This setting, from Arbor Productions (purchased by Daring Entertainment in 2009 and re-released under the title "Dawn of Legends" with several new rules and character options), details a world where super-beings (called "Neos") have existed publicly since World War II. Autumn Arbor takes place in a world where the laws and legal systems have evolved to handle the often ignored nuances of the comic book genre, and where the characters are depicted as real people beneath the costumes and powers, oftentimes with real-life issues such as parenting and addiction. The setting is also supported by a novel line; the first of which, Little Girl Lost, was written by Lee F. Szczepanik, Jr., Autumn Arbor co-creator. The Autumn Arbor Campaign Setting was a 2008 Origins Awards semi-finalist. The campaign world was further detailed in the Dawn of Legends sourcebook, which expanded the setting beyond the city of Autumn Arbor to include superhuman activities in nations such as China, Cuba, Germany, Japan, Mexico and others,including alterations in world history/world events outside the United States. The role of the federal government and the legal system in dealing with "Neos" is also given in greater depth.
Bedlam: Designed by James Thomson for Plain Brown Wrapper Games, the setting harkens back to the Iron Age of Comics, with more mature-themed characters, situations, and scenarios. It is set in Bedlam, the City of Nowhere (AKA the City of Rust). Bedlam is a deeply troubled metropolis, riven by economic hardship, corruption, and dark occult activities. While much of the setting details street-level heroes and villains, more powerful "four-color" characters also exist within the city. Player character heroes may chose to play to type as ruthless vigilantes or defy the genre by becoming role-models for Bedlam's downtrodden populance.

However, despite drawing from earlier decades of superhero history, the characters and setting reflect the more mature, diverse, and nuanced comics of the current era. Halt Evil Doer has been extensively supported and expanded on Green Ronin's Atomic Think Tank forums.
