d20 Modern is a roleplaying game designed by Bill Slavicsek, Jeff Grubb, Rich Redman, and Charles Ryan. It was published by Wizards of the Coast in November 2002, and uses the d20 System. The game provides a toolbox for staging campaigns in a range of modern settings.
A d20 Modern character can later, after meeting certain requirements, take levels in advanced classes. The advanced classes are much more specifically focused; examples include Soldier, Field Medic, and Techie.
There are prestige classes as well; these have stricter requirements, which are most likely arrived at through at least one advanced class, and are even more tightly focused in their roles, but these are not found in the core rules.
Feats are special abilities a character gains. Feats are less readily described because of the sheer variety of abilities they can grant the character. Unlike skills, feats do not have "skill points", but are rather a single thing you take that grants a bonus of some sort. A feat could allow a character to perform a special combat maneuver, enhance the use of one or more skills, or have some other more exotic effect.
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 of 2006. It is a remake of the Dark•Matter campaign setting for Alternity. It utilizes 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.
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 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 (film) (and its later follow up/remake 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.
