d20 Modern is a modern fantasy role-playing game system designed by Bill Slavicsek, Jeff Grubb, Rich Redman, and Charles Ryan. The system's core rulebook was published by Wizards of the Coast on November 1, 2002; by 2006, ten additional supplements were released. The game is based on the d20 System and the Dungeons & Dragons 3rd Edition ruleset. It includes various campaign settings along with the tools to build campaigns in modern/contemporary settings.

History

[edit]

Wizards released d20 Modern in 2002 while the company was overhauling its Star Wars role-playing game.[1]: 288  Wizards then expanded on the game, developing one of its settings into a sourcebook, the Urban Arcana Campaign Setting (2003). Wizards then extended this development of d20 even further, with the science-fiction game d20 Future (2004) as well as the historical game d20 Past (2005). Wizards ended this line in 2006 by updating their classic campaign setting Dark•Matter for d20 Modern.[1]: 292 

Alterations to the d20 System

[edit]

Basic classes

[edit]

In d20 Modern, each character is referred to as a hero. All heroes start with a first-level, basic class. Each basic class corresponds to one of the six ability scores in the d20 System. Each basic class has its own set of skills, feats, talents, saves, hit dice, wealth bonus, and so on. A beginning basic hero will become a more specific advanced-class hero at later levels, depending on which abilities a player favors for their character.

The six basic classes are:

  • The Strong Hero, based on Strength (STR). These heroes are brawny, and they greatly favor melee combat.
  • The Fast Hero, based on Dexterity (DEX). Nimble, quick, and able to evade most incoming attacks.
  • The Tough Hero, based on Constitution (CON). Difficult to take down and can resist most sicknesses.
  • The Smart Hero, based on Intelligence (INT). A know-it-all hero with an edge in brain-intensive skills.
  • The Dedicated Hero, based on Wisdom (WIS). A highly intuitive and vigilant hero.
  • The Charismatic Hero, based on Charisma (CHA). A hero with personal magnetism and a way with words.

Advanced Classes

[edit]

In addition to basic classes, there are also advanced classes. Similar to basic classes but with requirements to fulfill. There are 14 advanced classes for which a player character may qualify over time:

  • Acolyte
  • Bodyguard
  • Daredevil
  • Field Medic
  • Field Scientist
  • Gunslinger
  • Infiltrator
  • Investigator
  • Mage
  • Martial Artist
  • Negotiator
  • Personality
  • Soldier
  • Techie

Advanced classes can be less or more easily achieved depending on the hero's basic class. For instance, a Tough Hero can be an excellent candidate for Bodyguard or Daredevil, but would have more difficulty becoming a Techie or Acolyte.

At later levels, the player may choose to multi-class their hero; for example, a Strong and Dedicated Bodyguard (two basic classes, one advanced), or a Smart Investigator and Field Scientist (one basic, two advanced). There are no limitations in the rule set as to how many classes a hero may have, but two or three are typical. Dividing experience and character development between too many classes results in breadth at the cost of having weaker abilities in each class.

Some gamemasters (GMs) may set restrictions on certain advanced classes in their campaign. E.g., the advanced classes might require more experience points to acquire, or some might not be available until specific objectives have been reached in the game campaign. GMs may also entirely rule out certain classes, e.g. Acolyte and Mage because their spell-casting abilities do not fit the GM's hard sci-fi scenario.

Action Points

[edit]

One of the interesting additions to the system was the action points. Actions points are used by characters to affect game play greatly. Whenever a character spends one action point, the character receives a small boost in his or her skill checks, ability checks, level checks, or saving throws. There's a bit of restriction when and where to use them. As the character spends these points, they're very limited. However, through level advancement, he or she replenishes spent action points.

Feats, Skills, and Items

[edit]

In order to fit the d20 Modern setting, some skills and items are reworded and rebalanced, and both the feats and skills mechanics receive expansions.

Also included are game statistics for both modern weapons and "archaic" weapons, such as swords, axes, and crossbows.

Occupations and Wealth Bonus

[edit]

Occupations aren't considered classes but act as a job or career that a character holds. He or she may hold multiple occupations, but over time. There are over 19 different occupations and each with its own restrictions, such as age. As well, they open more options when choosing skills and higher Wealth bonus. The 19 occupations are: Academic, Adventurer, Athlete, Blue Collar, Celebrity, Creative, Criminal, Dilettante, Doctor, Emergency Services, Entrepreneur, Investigative, Law Enforcement, Military, Religious, Rural, Student, Technician, and White Collar.

Instead of using real world currency, such as United States dollar (USD) or Euro (EUR), it's been replaced with the Wealth bonus. It functions just like any real world currency: income, credit, debit, to deposit or withdraw, purchasing and selling, and so on. It also defines the characters' financial conditions, from being opulent to impoverishment. All characters have their own wealth. Determining wealth at first level, the player rolls a four-sided die two times (2d4), and then adds the results together. The result can be increased by occupation, the Windfall feat, and the Profession skill. Whenever the character advances in level, the player rolls a Profession check.

Campaign settings

[edit]

d20 Modern presents three sample campaign settings. These settings, unlike the rest of the book, feature the supernatural.

Shadow Chasers

[edit]

In this setting, evil monsters, usually from one or more parallel dimensions, roam free around the world. However, most people do not see these creatures for what they really are, seeing instead a vague approximation which is still plausible in that person's beliefs about reality. (See consensus reality.) For example, an ogre would appear to the average person as a very burly man. The player characters are somehow capable of seeing through this veil, and typically take on responsibility for defending humanity from the monsters. It originally appeared as a d20 mini-game in Polyhedron Magazine issue #150.

Agents of Psi

[edit]

In this campaign setting, magic (at least in the traditional sense) does not exist, but psychic capabilities called psionics do. Player characters typically work for a government agency investigating and/or using this quasi-supernatural force, but this is only a suggestion and is not strictly required by the rules. A novella taking place in this setting was published on the WotC website.

Urban Arcana

[edit]

In this setting, dragons rule the boardrooms and bugbears rule the streets. It is a world where monsters and magic exist, yet the human psyche just cannot fathom them and covers up all supernatural events. Some, however, break that barrier and become aware of the world around them, and help Mages, Acolytes, and other magical characters fight with monsters from another realm. This campaign setting combines aspects of the previous two settings (Shadow Chasers & Agents of Psi) and uses the concept that all three settings coexist in the same reality (at least in Urban Arcana).

Other settings

[edit]

Dark•Matter: Shades of Grey

[edit]
Polyhedron #167 - Global Positioning: Arctic Research Station & Dark•Matter: Shades of Grey

Dark•Matter: Shades of Grey is a d20 Modern mini-game of conspiratorial suspense presented in Polyhedron Magazine issue #167 (also known as Dungeon Magazine issue #108) and then as a stand-alone d20 Modern book, Dark•Matter, in September 2006. It is a remake of the Dark•Matter campaign setting for Alternity. It uses concepts from the core d20 Modern RPG rules and the Urban Arcana and d20 Menace Manual sourcebooks, which are also recommended for use to get the most from the setting.

Mecha Crusade

[edit]

Mecha Crusade was a d20 mini-RPG campaign setting in issue #154 of Polyhedron Magazine (Dungeon Magazine issue #95).

The setting was a take off of anime mecha series, like Mobile Suit Gundam or Macross.

Pulp Heroes

[edit]
Polyhedron #149 - Pulp Heroes

Pulp Heroes started as a d20 mini-RPG found in Polyhedron Magazine issue #149 (also known as Dungeon Magazine issue #90). Polyhedron #161 (also known as Dungeon #102) contained a d20 Modern "update" of the Pulp Heroes mini-game.

The setting allows one to play games that take place during the famous Pulp Era of literature, filled with ancient dinosaurs, power-hungry gangsters, vengeful vigilantes, amazing superheroes, evil Nazis, bizarre inventions, mystical psionics, hard-boiled detectives, trained martial artists, curious explorers, eldritch aliens, and various other fantastic people, places, and things.

The worlds of H. P. Lovecraft's Cthulhu Mythos and Sir Arthur Conan Doyle's The Lost World, and famous individuals like Jules Verne, H. G. Wells, Doc Savage, Tarzan, and Indiana Jones serve as perfect examples of this era.

Many elements of Pulp Heroes were adapted into the later d20 Past sourcebook.

Thunderball Rally

[edit]
Polyhedron #152 - Improved Initiative: d20 Innovation - Legendary Classes & Thunderball Rally

Thunderball Rally was the second mini-game in a brief series of previews for d20 Modern that appeared in the early issues of the third and last edition of Polyhedron Magazine, which was on the flipside of Dungeon Magazine.

Thunderball Rally, released as a preview for the d20 MODERN RPG in Polyhedron #152, is a d20 System mini-game about racing across the United States of America in 1976. The game creates an imaginary cross-country car race, and uses d20 System modern vehicle rules. The vehicle rules that were described in the game were also recommended for use with the previous d20 Modern mini-game preview Shadow Chasers (Polyhedron #150).

In Thunderball Rally, the player characters portray one of the crews in the largest, most lucrative, most illegal crosscountry road race in America. Examples of the genre include The Gumball Rally, Cannonball (and its later follow up/remake The Cannonball Run), The Blues Brothers, Death Race 2000, and Smokey and the Bandit, and iconic characters include the General Lee and Boss Hogg. Rules for Orangutan player characters subsequently appeared in Polyhedron #153 as a homage to the 1978 film Every Which Way but Loose.

Reception

[edit]

The 2002 Pyramid review highlights that compared to other non-fantasy modern settings "it appears that in many ways, Wizards of the Coast has been significantly more conservative when adapting the d20 System to a modern setting. d20 Modern retains many elements that other modern and ultramodern games dispense with or modify, such as iterative attacks and hit points. However, d20 Modern uses some aspects of the game that appeared in the d20 Star Wars game. [...] The fundamental difference between the approach to classes and the corresponding D&D classes is that the d20 Modern classes are much more general".[2]

Mark Theuar, for the gaming magazine Fictional Reality, wrote that he would "highly recommend this book to anyone wanting to play in a modern day rpg" and that "the interior artwork has sort of a graphic novel feel to it and it works very well for this setting".[3] He highlighted his enjoyment of the section on guns and that "combat is similar to Call of Cthulhu d20 meaning that you can get dead real quick. [...] My favorite aspect about the world background is that we're already living about 90% of it. As a GM all you have to do is fill in the last 10%. It's not like building or learning a whole new fantasy world from scratch".[3] Theuar also "particularly liked the Wealth system".[3]

Academic Kris Green also highlighted the d20 Modern Wealth system in the book Mathematics in Popular Culture (2012) and called it an "excellent example of abstraction".[4] Green wrote that "rather than force players to keep detailed records of every purchase a character makes and bank record he accesses, the d20 Modern designers created a single abstract quantity called 'Wealth' that determines how easy it is for a character to acquire equipment and resources. Players roll against the difficulty (which incorporates cost and availability as well as legality) of acquiring a good, and their wealth may change as a result of the roll, representing in the abstract the loss of assets".[4]

Legacy

[edit]

Charlie Hall, for Polygon, stated that "back in 2002, d20 Modern helped to breathe life into third edition Dungeons & Dragons, expanding the tabletop role-playing game into a far more contemporary setting — less swords and sorcery, more ninjas and automatic weapons".[6] Shannon Appelcline commented that d20 Modern was "sort of successful" in launching a "new wave of third-party" publication which used the d20 System, however, many other publishers had already begun creating modern and science-fiction d20 System publications before the release of d20 Modern.[7] This new wave included hundreds of third-party publications alongside the additional ten d20 Modern books Wizards of the Coast released. Appelcline wrote that "Sword & Sorcery was probably the most noticeable, with their licensed version of Gamma World (2003-2004), though they covered their bets by saying the books could be used with D&D 3e or d20 Modern. But, many other publishers put out large d20 Modern lines. Some of the most notable were Adamant's Thrilling Tales (2005-2007) and Mars (2006-2007) line, Green Ronin's varied d20 Modern rules and settings, which culminated in Damnation Decade (2006), and Mongoose's new editions of the classic Macho Women with Guns (2003, 2005)".[7]

Everyday Heroes

[edit]

In 2022, Jeff Grubb – co-creator of d20 Modern – announced an upcoming role-playing system titled Everyday Heroes which is based on the 5th edition Dungeons & Dragons ruleset via Wizard's Open Game License. Sigfried Trent, one of the lead designers, described the game as merger of "the theme, the setting, the mood, the feeling of d20 Modern" and "the rules, the simplicity, and the modularity of 5e".[6] Polygon called Everyday Heroes a "spiritual successor" to d20 Modern.[6]

This system will be published by Evil Genius Games and will include licensed settings such as Escape from New York, Highlander, Kong: Skull Island, Pacific Rim, Rambo, The Crow, Total Recall, and Universal Soldier.[6][8]

History

Development

The development of d20 Modern was initiated in 2001 by as an extension of the introduced in Third Edition, with the goal of creating a versatile ruleset for contemporary role-playing campaigns beyond fantasy settings. The project sought to capture the essence of action-oriented narratives inspired by films like Rambo and urban fantasy media such as , while drawing structural influences from prior Wizards publications including Star Wars Roleplaying Game and . Producer Bill Slavicsek, then Director of Research and Development, emphasized a focus on "cinematic role-playing" to to players interested in , horror, and post-apocalyptic . The core design team comprised experienced Wizards of the Coast staffers , Rich Redman, Charles Ryan, and Stan!, who collaborated on adapting core mechanics like character classes, skills, and combat to reflect real-world technology and societal elements. A key innovation was reimagining classes around core ability scores—such as the Strong Hero for physical prowess and the Smart Hero for intellectual pursuits—allowing greater flexibility for diverse character concepts without rigid archetypes. This approach addressed the limitations of traditional fantasy classes by emphasizing occupations and backgrounds to ground characters in modern life, with progression tied to action points for dramatic tension. Editor Michelle Carter played a crucial role in refining the manuscript, ensuring cohesion across the expanded 386-page core rulebook. During development, the team explored multiple campaign settings to broaden the system's appeal, including , shadow chases, and psychic investigations, but ultimately consolidated them into the core book while deferring deeper expansions. A proposed setting was cut for scope but later adapted into articles for Dragon and Polyhedron magazines. Charles Ryan highlighted the intent to "hit all of those [genres]... , Buffy the Vampire Slayer," reflecting a deliberate push toward genre-blending versatility. The rulebook was completed and published in November 2002, coinciding with the rise of the to encourage third-party content.

Overall, Wizards produced the core book plus ten supplements from 2002 to 2006, fostering a diverse ecosystem before the line went dormant.

Core System

Classes and Character Creation

Character creation in d20 Modern follows a structured process adapted from the , emphasizing modern-day realism and versatility for urban or contemporary campaigns. Players begin by determining ability scores—Strength, Dexterity, , , , and —using methods such as point buy (e.g., assigning values from a standard array like 15, 14, 13, 12, 10, 8), rolling 4d6 and dropping the lowest die, or straight 3d6 rolls ranging from 3 to 18. Race selection defaults to , with class skill points already incorporating the racial bonuses of 4 extra skill points at 1st level, 1 extra per additional level, and 1 bonus feat at 1st level to reflect diverse backgrounds. Next, players choose allegiances, such as personal ideals, organizations, or philosophies (e.g., loyalty to a or cause like "good" or "chaos"), which influence and certain mechanics without enforcing a strict alignment system. The process continues with selecting an occupation, a pre-class role like Academic (bonus to skills), Adventurer (versatile feat and access), Doctor (healing focus), or (combat proficiency), which grants starting feats, class skills, (+1 or +2), and a Wealth bonus for acquisition. Players then pick one of the six basic classes, each tied to a primary score and designed for 1st-level heroes, determining hit points, points per level, base attack bonus, saving throw progressions, and class features. Note that the points for basic classes incorporate the standard racial bonuses. points are allocated based on the class formula (e.g., (points per level) × 4 at 1st level, plus modifier), prioritizing class skills like Drive, Computer Use, or for modern applicability. Feats are selected at 1st level (one automatic plus the bonus feat plus any from occupation), with additional feats every three levels or via class bonuses, focusing on practical abilities like Personal Firearms Proficiency or Point Blank Shot. Wealth is calculated as a bonus score (starting at 2d4 + occupation bonus + (Wisdom modifier + ranks in skill)) used for purchase checks rather than gold, enabling access to contemporary gear like firearms or vehicles. Combat statistics follow: hit points (class Hit Die roll or maximum at 1st level, plus modifier), Defense (10 + Dexterity + class bonus), Initiative (Dexterity + class), base attack (class progression), and saving throws (good in two, poor in one per class). is purchased via Wealth checks, and final details include action points (5 + ½ character level for heroic actions like adding to rolls) and background elements like name and personality. This system supports multiclassing after 1st level, allowing up to three classes without experience penalties, blending basic class foundations with advanced classes at higher levels for specialization. The six basic classes provide archetypal starting points, each with 10 levels of progression and no inherent spellcasting, differing from by emphasizing technology, firearms, and urban survival over fantasy magic. The Strong Hero (key ability: Strength; Hit Die: d8; skill points: 3 + Int modifier) excels in physical power and , gaining features like Melee Smash (+1d6 damage on improvised weapons), Extreme Effort (temporary Strength boost for checks or damage), and Ignore Hardness (bypassing object resilience), with bonus feats such as Power Attack. It suits frontline combatants, prioritizing brawn over agility in modern brawls. The Fast Hero (Dexterity; d8; 5 + Int modifier) focuses on speed and evasion, with abilities including Evasion (half or no damage from area effects), Increased Speed (+5 ft. per feature), Uncanny Dodge (retain Dexterity to Defense when flat-footed), and Defensive Roll (halved damage once per day), plus feats like and Mobility. Ideal for agile scouts or drivers, it adapts D&D's rogue-like mobility to pursuits and gunfights. The Tough Hero (Constitution; d10; 3 + Int modifier) emphasizes endurance, featuring Damage Reduction (1/—, increasing to 3/—), Energy Resistance (5 to one type, +5 per feature), Remain Conscious (act at 0 hp), Second Wind (heal 1d8 + level or half level hp daily), and Robust (+4 vs. /), with feats like . It represents resilient survivors, replacing D&D's fighter durability with gritty, non-magical toughness for prolonged engagements. The Smart Hero (Intelligence; d6; 9 + Int modifier) handles intellect and invention, with Savant (+1 to +5 on one , multiple uses), Plan (reroll a failed check or +2 on next action), and research-oriented bonuses, plus feats like Educated and Gearhead for technical aptitude. Geared toward hackers or engineers, it shifts D&D's wizard intellect to contemporary problem-solving without arcane elements. The Dedicated Hero (Wisdom; d6; 5 + Int modifier) aids allies through insight and , gaining Empathy (+2 to Sense Motive or checks), Knack (+1d4 hp via skill), Touch (heal 2× level or level hp, 3/day), and Aware (+1 Spot/Listen), with feats like . It supports team dynamics like a modern cleric analogue, focusing on and non-supernatural . The Charismatic Hero (Charisma; d6; 7 + Int modifier) leads through influence, with Charm (+3 Charisma checks or attitude improvement), Fast-Talk (temporary Bluff synergy), Coordinate (+1 to allies' actions), Favor (weekly aid), and Inspiration (+2 morale), plus feats like Renown. Suited for negotiators or celebrities, it channels D&D's bardic into social engineering for urban intrigue.

Action Points and Progression Mechanics

In d20 Modern, action points serve as a key resource for heroic characters, allowing players to influence outcomes in critical moments and emphasizing the system's cinematic, action-heroic tone. Characters begin play with 5 action points at 1st level, and upon gaining each subsequent level, they receive additional action points equal to 5 plus one-half their new character level (rounded down). For example, advancing to 2nd level grants 6 action points (5 + 1), while reaching 8th level provides 9 (5 + 4). This cumulative system results in a growing pool—such as 56 total action points by 8th level—reflecting increasing heroic capability without a hard cap. Only characters with levels in heroic classes (basic or advanced, as opposed to ordinary non-player characters) gain and spend action points, underscoring the distinction between protagonists and ordinary folk. Action points are spent as a free action, limited to one per round, to either augment a d20 roll or enable special effects. The primary use adds a variable bonus to any attack roll, , skill check, ability check, or level check, declared after the die is rolled but before the result is revealed; the bonus equals the highest roll on 1d6 at levels 1–7, 2d6 at levels 8–14 (taking the highest), or 3d6 at levels 15–20. This cannot combine with taking 10 or 20 on a roll and provides a scalable edge, equivalent in power to a low-level magic item (roughly 100 gp per character level). Alternative expenditures include stabilizing at 0 hit points without a check, activating certain class talents (such as a Fast Hero's Defensive Roll for a Reflex save against area effects), or enhancing feats temporarily (e.g., doubling the dodge bonus from ). Some advanced classes, like the Gunslinger, allow spending points for extra damage on successful attacks (+3d6). These mechanics encourage tactical decisions, as points cannot be traded or sold, and game masters may adjust treasure awards to offset their potency. Character progression in d20 Modern revolves around accumulating experience points (XP) through encounters, roleplaying, and objectives, mirroring the d20 System's structured advancement while adapting to modern genres. XP awards are divided into personal (for individual contributions) and story (for group milestones), with totals determining level-ups via the following table:
Character LevelExperience Points Required
1st0
2nd1,000
3rd3,000
4th6,000
5th10,000

17th136,000
18th153,000
19th171,000
20th190,000
Upon leveling, characters select or advance a class, gaining hit points (via Hit Die roll plus modifier), skill points (based on class and , with maximum ranks equal to level + 3 for class skills), base attack bonus, bonuses, and class features. Every fourth level (4th, 8th, 12th, 16th, 20th), scores increase by 1 point total (player's choice), while feats are acquired at 1st level (two feats) and every third level thereafter. Multiclassing allows adding new classes at 1st level if prerequisites are met, with total character level dictating overall bonuses like action point dice scaling and skill maxima, promoting flexible builds suited to urban, sci-fi, or horror campaigns. This XP-driven system caps at 20th level, emphasizing growth over endless power escalation.

Skills, Feats, and Equipment

In d20 Modern, skills represent a character's trained or inherent to accomplish specific tasks, resolved through a core mechanic of rolling a d20, adding skill ranks (points invested during character creation and leveling), and the relevant modifier, then comparing the total to a Difficulty Class (DC) set by the task's complexity. Characters receive skill points per level based on class (e.g., 5 + modifier for a Fast ) and can allocate up to level + 3 ranks in class skills or half that in cross-class skills, with some skills requiring to use effectively at all. Under non-stressful conditions, players can "take 10" (add 10 instead of rolling) or "take 20" (roll multiple times for the highest result, taking 20 times longer), promoting strategic planning over pure chance. DCs range from simple (5) to nearly impossible (40+), and opposed skill checks pit one character's roll against another's, such as Bluff versus Sense Motive in scenarios. Representative skills adapt the to modern contexts, emphasizing practical abilities like technology and urban survival. For instance, Computer Use (Intelligence-based, trained only) handles hacking or with DCs escalating for security levels (e.g., DC 20 for basic access, higher for encrypted networks), while Drive (Dexterity-based) governs maneuvers, requiring checks only for stunts like high-speed pursuits. Treat Injury (Wisdom-based) covers medical aid, with DCs for tasks like (DC 15, stabilizes a dying character) or (DC 30, restores hit points over hours). Other examples include Investigate for forensic analysis (e.g., DC 15 to spot clues at a ) and Repair for fixing gear (e.g., DC 20 to mend a , restoring 2d6 hit points in 1 hour with tools). Armor check penalties apply to physical skills like Climb or Hide, simulating realistic , and class-specific bonuses (e.g., +2 from ) further tailor skills to heroic archetypes. Feats provide specialized advantages that differentiate characters, selected at 1st level (one general feat plus one from class options) and additional ones at even levels or via class bonuses, often with prerequisites like minimum ability scores or prior feats. They enhance combat, skills, or utility without altering the core d20 resolution, stacking where applicable and sometimes granting unique actions, such as trading attack accuracy for defense. Basic feats have no prerequisites and offer broad utility, while advanced ones build on them for specialization, reflecting a modular progression that encourages diverse builds in modern or genre campaigns. Examples illustrate feats' role in customization: Point Blank Shot eliminates range penalties and adds +1 to attack and damage rolls within 30 feet for ranged weapons, ideal for urban shootouts. Personal Firearms Proficiency removes the -4 non-proficiency penalty for pistols and , a foundational feat for action-oriented characters. Combat Expertise ( 13 prerequisite) allows subtracting up to -5 from attack rolls to add that amount to Defense as a dodge bonus, enabling tactical risk-reward decisions in firefights. Defensive feats like Improved Initiative grant +4 to initiative rolls for quicker combat starts, while skill boosters such as provide +2 to Listen and Spot, enhancing awareness in investigations. Some feats, like Burst Fire (requiring firearm proficiencies), enable full-auto bursts with automatic weapons, dealing extra damage at the cost of ammunition. Equipment in d20 Modern supports modern realism through a purchase system based on Wealth bonus (starting at 2d4 + occupation bonus + (Wisdom modifier + ranks in Profession skill), rolled as d20 + bonus vs. item DC), where successful buys deduct from future rolls to simulate economic impact, and high-value acquisitions may require black market dealings (adding +10 to DC for illegal items). Items are categorized by size, weight, and restriction level (licensed, restricted, or illegal), with carrying capacity limited by Strength (e.g., medium load for Strength 10 is up to 66 pounds, imposing -3 penalties to Balance, Climb, and similar skills). Proficiency feats mitigate penalties for armor or weapons, and equipment degrades over use or damage, requiring Repair checks to maintain. Core equipment types include personal gear, weapons, armor, and vehicles, balanced for contemporary threats. Basic items like a (DC 5, 1 pound) or cell phone (DC 9) enable everyday functionality, while combat gear features firearms such as the .45 pistol (damage 2d6, range 50 feet, DC 14, restricted) or shotguns (2d8 damage, DC 16). Armor ranges from leather jackets (+2 equipment bonus to Defense, no penalty, DC 12) to vests (+4 bonus, -1 penalty to physical skills, DC 18, licensed), providing layered protection without the arcane focus of fantasy systems. Vehicles like sedans (speed 150 feet, DC 20) or motorcycles (speed 220 feet, DC 18) integrate into chases via Drive checks, with damage thresholds reflecting durability (e.g., a has 40 hit points). This system emphasizes , as Wealth checks prevent unlimited hoarding and encourage narrative ties to acquisitions.

Campaign Settings

Urban Arcana and Supernatural Themes

Urban Arcana serves as the inaugural for the d20 Modern roleplaying game, introducing a fusion of contemporary urban life with overt elements drawn from fantasy traditions. In this setting, the modern world—complete with cities, technology, and everyday societal structures—intersects with , mythical creatures, and arcane forces, creating opportunities for players to explore adventures where heroes wield both firearms and spells against otherworldly threats. Published by in 2003, the setting expands the core d20 Modern rules by incorporating new races, classes, and mechanics tailored to this hybrid environment. At the heart of Urban Arcana's supernatural framework is the Shadow, a nebulous mystical plane that acts as a conduit between and distant fantasy realms. This Shadow has recently "torn," allowing hordes of fantasy creatures—collectively known as Shadowkind, including elves, orcs, dwarves, and monstrous entities like dragons and demons—to spill into the modern world. These beings integrate into urban society, often concealing their true natures to avoid detection, while magic becomes a tangible force that permeates hidden corners of cities, manifesting through ley lines, incantations, and artifacts. The setting emphasizes themes of secrecy and duality, where the lurks beneath the surface of mundane life, rationalized away by most humans through a "weirdness censor" that prevents widespread panic—such as perceiving a as merely a disheveled vagrant. Supernatural themes in Urban Arcana revolve around the tension between the visible modern world and its concealed arcane underbelly, exploring how ancient s clash with contemporary . Players encounter expanded systems, including 104 new spells and modern-adapted items like the Cloudkill (a infused with arcane poison) or the Bladegun (a that shoots enchanted blades), which bridge fantastical powers with urban warfare. Creatures from lore, such as vampires operating nightclubs or gnomes running tech startups, embody these themes by navigating human society, forming cabals, or engaging in shadow conflicts over mystical sites. Secret organizations, including mage guilds and monster-hunting societies, further underscore the narrative of hidden battles against incursions, mobsters allied with demons, or corporate overlords exploiting arcane resources. The setting's design encourages campaigns rooted in players' own hometowns, transforming familiar urban landscapes—malls, subways, and skyscrapers—into arenas for intrigue, without prescribing a rigid to maintain flexibility for game masters. This approach highlights themes of wonder and peril in the everyday, where cell phones might receive cursed emails or could ferry spectral passengers, blending horror, , and mystery in a concealed magical realism.

d20 Future and Sci-Fi Expansions

d20 Future is a core expansion supplement for the d20 Modern roleplaying game, published by in 2004, designed to facilitate campaigns by integrating advanced technology, , and futuristic elements into the core ruleset. It builds upon the modern-day framework of d20 Modern by introducing mechanics for genres ranging from to , allowing gamemasters to create settings involving alien worlds, post-apocalyptic societies, and interstellar conflicts. The supplement emphasizes modular rules that can be selectively applied to match the desired technological scope, ensuring compatibility with the base game's character creation, combat, and progression systems. A foundational element of d20 Future is the Progress Levels (PL) system, which categorizes technological advancement on a scale from PL 0 (, featuring basic tools like clubs and ) to PL 9+ (exotic technologies potentially involving or space folding). Each level represents societal and scientific milestones, such as PL 5 (, with computers and early space travel) or PL 7 (Gravity Age, including starships and powered armor), influencing equipment availability—items from higher PLs incur purchase penalties in lower-level societies, while adds complexity. This system enables gamemasters to define campaign tech baselines, such as a PL 6 fusion-powered or a PL 8 energy-shielded starfighter fleet, providing conceptual structure for world-building without dictating exhaustive details. New occupations tailored to sci-fi archetypes, like the tech-savvy Operator or the exploratory Scout, expand character options alongside modified skills (e.g., enhanced uses for Knowledge [technology]) and feats (e.g., Gearhead for ). The supplement introduces 12 advanced classes to support specialized sci-fi roles, each building on basic class prerequisites and offering unique abilities for high-level play. Representative examples include the Helix Warrior (Strong hero base), which leverages genetic enhancements for combat prowess; the Engineer (Smart hero base), focused on inventing and repairing advanced machinery; and the Xenophile (Smart hero base), an expert in alien cultures and biology for diplomatic or exploratory scenarios. Other classes like the Dogfighter (Fast hero, specializing in vehicle combat) and the Ambassador (Charismatic hero, emphasizing interstellar negotiation) allow characters to embody tropes from films like or Star Wars. Equipment sections detail futuristic gear across –8, including energy weapons (e.g., plasma rifles at PL 6), advanced armor (e.g., inertial dampeners at PL 7), and universal gadgets for customization, such as modular weapon attachments. Beyond personal gear, d20 Future provides comprehensive rules for large-scale sci-fi elements, including starship combat with modular designs and crew roles, ground and space vehicles for traversal, for powered exoskeletons in battle, robots as allies or adversaries with AI programming, for bodily augmentation (e.g., neural interfaces), for post-apocalyptic or evolutionary themes, and for creating alien species with custom physiologies. These mechanics prioritize balance with the , using familiar dice rolls for piloting chases or hacking networks while introducing scale for epic encounters, such as boarding actions on interstellar vessels. Campaigns can mix these elements, like a PL 6 hacker infiltrating a derelict ship. In 2006, released d20 Future Tech as a dedicated supplement to further expand technological options, focusing on detailed gadgets, weapons, and upgrades for characters, vehicles, s, and without altering core rules. It builds on d20 Future's subsystems by providing over 100 new items, such as advanced components and experimental energy sources, organized by PL for easy integration. This 96-page book enhances customization, allowing players to equip heroes with bleeding-edge tech like adaptive fields or drives, while maintaining compatibility for mixed-genre adventures. Representative additions include expanded gadgets for versatility in combat and modules for tactical depth, emphasizing innovation in sci-fi hardware.

Other Genre Settings

In addition to the urban fantasy and science fiction expansions, the d20 Modern line included supplements for historical, post-apocalyptic, and conspiracy-themed campaigns, broadening the system's applicability across diverse genres. These settings provided specialized rules, advanced classes, equipment, and narrative frameworks to adapt the core mechanics to periods and themes outside contemporary or futuristic narratives. The d20 Past supplement, released in March 2005, focused on historical campaigns spanning from 1450 to 1950, offering tools to blend realism with adventure in eras like the Age of Sail, the Victorian period, and . It introduced era-specific advanced classes such as the Duelist for swashbuckling intrigue, the Mounted Warrior for frontier conflicts, and the Field Medic for wartime scenarios, alongside modified equipment lists reflecting technological limitations, like black powder firearms and period armor. Sample campaign models included "Age of Adventure," emphasizing global exploration and piracy in the ; "Shadow Stalkers," a horror-tinged Victorian setting with secret societies and threats; and "Iron Imperative," depicting gritty espionage and combat. These elements allowed gamemasters to create campaigns prioritizing historical accuracy while incorporating d20 Modern's action-oriented progression, such as adapting action points for era-appropriate challenges like naval chases or . d20 Apocalypse, published in June 2005, equipped players for survival-focused narratives in ruined worlds following cataclysmic events, with rules for scavenging, , and factional warfare in post-apocalyptic environments. Key additions included advanced classes like the Road Warrior for vehicular combat and the Scavenger for , plus mechanics for environmental hazards, effects, and improvised weaponry from junkyard materials. The book outlined three sample settings: "Atomic Sunrise," a Mad Max-inspired wasteland after nuclear devastation; "Earth Inherited," a apocalypse involving demonic incursions post-Rapture; and "Winds of Fire," the aftermath of an with lingering extraterrestrial threats. These frameworks emphasized themes of resilience and moral ambiguity, integrating d20 Modern's skill and feat systems to handle long-term campaigns centered on rebuilding society or nomadic survival. d20 Dark•Matter, issued in September 2006 as an update to the earlier campaign setting, delved into modern-day horror, where players investigated shadowy organizations, alien incursions, and phenomena. It featured advanced classes such as the Infiltrator for and the Psi-Op for psychic abilities, complemented by new feats and equipment like surveillance gear and anomalous artifacts. The setting revolved around the Hoffmann Institute, a covert agency combating "dark matter" entities including extraterrestrials, , and eldritch forces, with plot hooks drawn from real-world tropes like government cover-ups and secret societies. Unlike the overt fantasy of Urban Arcana, d20 Dark•Matter stressed subtle, investigative gameplay, using d20 Modern's core rules to simulate paranoia-driven stories where elements emerge gradually through clues and alliances.

Core Rulebooks

The primary core rulebook for the d20 Modern roleplaying game is the d20 Modern Roleplaying Game Core Rulebook, a 320-page hardcover volume published by Wizards of the Coast on November 1, 2002. Authored by Bill Slavicsek, Jeff Grubb, Rich Redman, and Charles Ryan, it adapts the d20 System from Dungeons & Dragons Third Edition to contemporary settings, enabling campaigns involving espionage, urban intrigue, or supernatural elements in the modern world. The book serves as a self-contained foundation, covering character creation, gameplay mechanics, equipment, and gamemastering tools without requiring additional purchases for basic play. The rulebook's structure emphasizes accessibility for players familiar with fantasy RPGs while introducing modern-themed innovations. It begins with foundational rules in chapters on abilities, races (primarily humans with optional variants), and classes, including six base classes—Strong Hero (focused on physical power), Fast Hero (emphasizing agility), Tough Hero (for endurance), Smart Hero (intelligence-based), Dedicated Hero (willpower and healing), and Charismatic Hero ()—each offering 10 levels of progression with unique class features like bonus feats or skill emphases. Starting occupations, such as Academic or Criminal, provide initial skill bonuses, while allegiances and mechanics add narrative depth by influencing social interactions and NPC responses. Subsequent chapters detail skills (over 30, including Drive, Investigate, and variants for modern topics like or current events), feats (such as Point Blank Shot for firearms or Personal Firearms Proficiency), and , with wealth tracked via a score system rather than gold, allowing purchases of weapons, vehicles, and gadgets through Difficulty Class (DC) checks. Combat rules adapt the for ranged firearms and vehicles, incorporating initiative, attack rolls, damage types (e.g., ballistic vs. slashing), and special maneuvers like autofire or cover. A dedicated chapter on vehicles covers civilian and military options, including chase rules, collisions, and repairs, while advanced topics introduce optional supernatural elements like spells, , and creatures (e.g., or aberrations) for genre flexibility. The book concludes with gamemastering guidance, including campaign models (e.g., espionage thriller or post-apocalyptic survival) and challenge creation, supported by appendices with tables for quick reference, such as equipment stats and carrying capacities. Action points—a resource for heroic surges, granting rerolls or bonuses—distinguish progression, accumulating based on level to enhance cinematic play without altering core d20 resolution (d20 roll + modifiers vs. DC). This single volume encapsulates the system's emphasis on adaptable, narrative-driven adventures in realistic or fantastical modern contexts.

Supplements and Accessories

Wizards of the Coast released a series of supplements for d20 Modern between 2003 and , expanding the core rulebook with additional content for character options, equipment, monsters, and campaign settings. These supplements built on the d20 System's adaptability, providing tools for various modern and genre-specific scenarios while maintaining compatibility with the base rules. By , at least ten such books had been published, focusing on themes like weaponry, apocalyptic events, historical recreations, and futuristic elements.

Reception

Critical Reviews

Critical reception to d20 Modern was generally positive among RPG reviewers, who appreciated its adaptation of the for contemporary settings while highlighting its versatility for genres beyond fantasy. Reviewers noted the core rulebook's comprehensive 384-page structure, which includes detailed sections on character creation, skills, feats, , and gamemastering, making it accessible for both new and experienced players familiar with Dungeons & Dragons 3rd Edition. The system's modular design, allowing for easy customization across modern, , and sci-fi campaigns, was frequently praised as a strength that elevated the d20 mechanics for non-medieval play. Key innovations such as the six basic hero classes (e.g., Strong Hero, Fast Hero), tied to primary ability scores for streamlined progression, and the introduction of action points—a pool of non-regenerating bonuses to enhance rolls—were lauded for adding cinematic flair and player agency without overcomplicating the rules. The abstract wealth system, using a bonus and purchase DCs instead of tracked , was seen as a clever solution to modern , reducing the tedium of tracking. Advanced classes, resembling prestige classes but accessible earlier, further expanded character options, with reviewers highlighting their thematic fit for roles like or . Production quality, including clean layout and effective tables, also received commendations, though artwork was described as high-quality yet uninspired and inconsistent across contributors. Criticisms centered on lingering elements from D&D that felt mismatched for modern realism, such as the hit point system, which reviewers argued inadequately simulated injury and lethality in firearm-heavy scenarios. Firearm rules were faulted for lacking damage variety, diminishing incentives for diverse weapon choices, while nonlethal damage mechanics were deemed ineffective and unbalanced, often failing to penalize combatants realistically. Some found the included campaign models, like Shadow Chasers, too derivative of D&D tropes, limiting the system's departure from fantasy roots, and the index was criticized as insufficient for the book's scope. Overall ratings ranged from 4/5 to 5/5 on review sites, positioning d20 Modern as a solid but not revolutionary entry for d20 enthusiasts.

Player and Community Feedback

Player feedback on d20 Modern has been generally positive among those familiar with the , with users appreciating its adaptability for contemporary settings like urban intrigue or near-future adventures. On RPGGeek, the game holds an average rating of 5.70 out of 10 from 90 user ratings, reflecting a solid but not exceptional reception in the broader RPG community. Players often highlight the core rulebook's modular class structure—featuring six basic classes tied to ability scores and twelve advanced classes—as a strength, allowing for customizable heroes that blend skill-based progression with level advancement in a way that feels balanced for non-fantasy campaigns. The wealth system, which uses a simple bonus to determine rather than tracking exact , has been praised for streamlining and enabling cinematic action without bogging down play. Criticisms from players frequently center on the game's combat-oriented design, which inherits much of its mechanics from 3rd Edition, leading to perceptions of it being overly skirmish-focused and less suited for pure roleplaying or simulationist modern scenarios. Reviewers note that feats and skills emphasize tactical encounters, with vehicle chases and firearms rules sometimes feeling cumbersome or abstract compared to dedicated modern systems. Advanced classes are often described as niche and power-gamey, potentially limiting character diversity, while the hit point system is seen as inadequate for realistic injury portrayal in a world of guns and grit. Additionally, the lack of extensive official adventure support post-launch contributed to mixed experiences, with many players relying on homebrew content to sustain long-term campaigns. The community around d20 Modern remains niche but enduring, with ongoing discussions and third-party supplements keeping it alive two decades after release. Its core rulebook achieved Platinum bestseller status on DriveThruRPG by 2023, indicating sustained player interest and sales in digital formats. This has fostered a dedicated following that values the system's openness under the , leading to fan adaptations and influencing modern RPGs like Everyday Heroes, a 5th Edition refresh that addresses some original pain points based on community input. Overall, while not as universally beloved as its fantasy counterpart, d20 Modern is regarded by enthusiasts as a foundational toolkit for genre-blending play.

Legacy

Influence on Modern RPG Design

d20 Modern significantly expanded the applicability of the d20 System, originally developed for Dungeons & Dragons 3rd Edition, by adapting its core mechanics to contemporary and urban settings, thereby demonstrating the system's genre-agnostic potential. Released in 2002, it shifted focus from medieval fantasy to modern-day action scenarios involving firearms, vehicles, and urban environments, influencing subsequent RPG designs to prioritize modular rules for diverse narratives. This adaptability encouraged designers to view the d20 framework as a versatile engine for non-fantasy genres, paving the way for hybrid systems that blend tactical combat with everyday realism. A key aspect of its influence stemmed from its integration with the (OGL), which allowed third-party publishers to build upon the d20 System's open content, including elements from d20 Modern. This fueled a boom in d20-compatible products during the early 2000s, with publishers like and Green Ronin creating modern-themed supplements and full games that refined mechanics such as wealth systems and skill progressions for real-world simulations. For instance, d20 Modern's abstracted Wealth mechanic, which treated purchasing power as a score rather than itemized currency, inspired streamlined economic rules in later RPGs to reduce bookkeeping in contemporary campaigns. In terms of character design, d20 Modern introduced "hero classes" and action archetypes—broad categories like Fast Hero or Tough Hero—that emphasized role flexibility over rigid fantasy tropes, influencing modern RPGs to adopt similar progression trees for versatile protagonists. These elements addressed the challenges of balancing with everyday abilities, such as or hacking, and were echoed in games seeking cinematic yet grounded playstyles. Co-creator highlighted this enduring impact, stating that d20 Modern "did for the D&D of its age" what updated systems could do for evolving traditions. The game's legacy persists through direct successors like Everyday Heroes (2023), developed by original d20 Modern designers including Grubb, which merges its thematic focus on modern heroism with Dungeons & Dragons 5th Edition's streamlined rules. Lead designer Sigfried Trent described it as combining "the theme, the setting, the mood, the feeling of d20 Modern" with 5e's modularity, resulting in a system that supports licensed properties like Rambo and Highlander for action-oriented adventures. This evolution underscores d20 Modern's role in bridging tactical d20 gameplay with accessible, narrative-driven design in contemporary RPGs.

Successors and Adaptations

Following the release of d20 Modern in 2002, the Open Game License (OGL) facilitated a wide array of third-party adaptations and expansions, allowing publishers to build directly on its core mechanics for diverse settings. One prominent example is the sixth edition of Gamma World (2004), published by Sword & Sorcery Studios under license from Wizards of the Coast, which adapted the post-apocalyptic role-playing game to the d20 Modern system. This version incorporated d20 Modern's hero classes, action points, and equipment rules while introducing mutation tables and technological artifacts unique to the Gamma World universe, enabling campaigns in a ruined future Earth blending science fiction and fantasy elements. Other third-party works leveraged d20 Modern for genre-specific content, such as d20 Apocalypse (2004) by Crafty Games, which provided rules for survival in post-catastrophe worlds, including scavenging, radiation hazards, and improvised weapons, further extending the system's versatility beyond urban contemporary settings. These adaptations highlighted d20 Modern's , influencing indie publishers to create compatible supplements for horror, , and historical themes without official endorsement from . In more recent years, Everyday Heroes (2023) emerged as a , developed by Evil Genius Games with contributions from original d20 Modern designer . This standalone role-playing game updates d20 Modern's contemporary framework to the fifth edition Dungeons & Dragons ruleset, featuring six core archetypes (e.g., Strong Hero, Agile Hero), 20 specialized classes (e.g., , Martial Artist), and mechanics for modern combat, chases, and wealth management tailored to real-world and cinematic scenarios from the 1900s to near-future settings. The system supports licensed adventure modules based on action films like Rambo and Total Recall, preserving d20 Modern's emphasis on heroic action in everyday environments while streamlining combat and progression for broader accessibility. However, the legacy of Everyday Heroes has been complicated by controversies surrounding its publisher, Evil Genius Games, in 2024 and 2025. Multiple employees resigned in early 2024 citing ethical concerns, including the company's involvement in NFT and promotions despite stated policies against them. The publisher also faced a lawsuit from over a canceled RPG adaptation, which was amicably settled, and drew criticism for attempts to suppress negative coverage through legal threats and demands to remove online posts. As of November 2025, these issues have impacted the game's community reception and ongoing development.
