GURPS Infinite Worlds is a supplement for the Fourth Edition of the GURPS role-playing game, published by Steve Jackson Games in 2005. Written by Kenneth Hite, Steve Jackson, and John M. Ford, it expands upon the campaign setting of conflict between the Infinity Patrol and Centrum across a multiplicity of alternate history Earths presented in the Fourth Edition GURPS Basic Set (and originating in the Third Edition supplements GURPS Time Travel, GURPS Alternate Earths, and GURPS Alternate Earths II). Several of the parallel Earths in the Alternate Earths volumes reappear - sometimes in slightly altered form - in Infinite Worlds: Reich-5, Caliph, Dixie, Ezcalli, Gernsback, Roma Aeterna, and Shikaku-Mon.

Armada-2

So named because it is the second world discovered by the Infinity Patrol in which the Spanish Armada was victorious over the English in 1588, Armada-2 is a world just now (in "current year" 1812) emerging from the shadow of Catholic Spanish hegemony, with Sweden and industrialised Egypt and Huguenot Nouvelle France. The Spanish Armada (Old Spanish: Grande y Felicísima Armada, large and most fortunate fleet; but called by the English, with ironic intention, la Armada Invencible, the Invincible Fleet) was a fleet sent by King Philip II of Spain in 1588 in a failed attempt to bring an end to... In the 16th and 17th centuries, the name of Huguenots came to apply to members of the Protestant Reformed Church of France. ...

Attila

A parallel where city-razing Mongol hordes under Genghis Khan destroyed first Beijing and then all the cities of Europe, where now their descendants (in "current year" 2004) rule an entirely nomadic Europe. The world was mistakenly named for Attila the Hun by early Infinity Patrol researchers who were confused as to which nomadic leader was responsible.

Azoth-7

When Isaac Newton discovered the secret of the philosopher's stone in 1693, he paved the way for an Alchemical Revolution that has left Azoth-7 dominated by the magical might of Britain, Venice, Prussia, and Spain by "current year" 1780. bitch!11 ... The philosophers stone, a longtime holy grail of Western alchemy, is a mythical substance that supposedly could turn inexpensive metals into gold and/or create an elixir that would make humans immortal. ...

Bonaparte-4

In Bonaparte-4 the French emperor Napoleon sacrificed the romance of an Egyptian campaign (which he conducted in 1798 in our timeline) for a stealthy invasion of Ireland, granting him victory over Britain. By "current year" 2024, the world is divided between French, Japanese, Russian, and Brazilian Empires, along with the United States and the Russian Republic, and the world has achieved a stage of technological achievement and social disaffection and tension reminiscent of cyberpunk fiction.

Britannica-3

The success of the rebellion of James, Duke of Monmouth against James II of England in 1685 is the point of divergence between our own world and Britannica-3; wiser and more Protestant rule in Britain meant that tensions with the North American colonies never reached the point of rebellion as they did in real history. Despite the rise of other strong European powers, the world is free of major conflicts, which can be attributed to the strong influence of Centrum in this parallel. James Crofts, later Scott, 1st Duke of Monmouth, 1st Duke of Buccleuch (April 9, 1649–July 15, 1685) recognised by some as James II of England and James VII of Scotland, was born in Rotterdam in the Netherlands, the son of Charles II and his mistress, Lucy Walter, who had...

Campbell

Named for the early death of influential science fiction editor Joseph W. Campbell which occurred in this parallel but not in real history, Campbell is a world notable for the poverty of its scientific advancement. While military applications of scientific research advanced rapidly enough, science as an intellectual pursuit became associated exclusively with death, destruction, and catastrophe, leading to an anti-scientific wave of pacifist Luddism and charismatic religious revival in the 1960s. Lacking the positive fruits of scientific inquiry, the world heads (in "current year" 2004) through ecological disaster and failing economies to a nigh-inevitable showdown between its capitalist and communist societies. Science fiction is a form of speculative fiction principally dealing with the impact of imagined science and technology, or both, upon society and persons as individuals. ...

Centrum Beta

One of the most important parallel Earths from the Infinity Patrol's point of view, Centrum Beta appears to be an exact copy of the home parallel their great rival Centrum - except that the "current year" is only 1895. Understanding Centrum Beta as it is now might give the Infinity Patrol the key to understanding and besting Centrum proper.

Friedrich

This parallel world is named for the Holy Roman Emperor Friedrich I Barbarossa, who in this timeline managed to be the great imperial unifier and conqueror that the vagaries of fortune prevented him from being in our history. In "current year" 1219, seventeen years after his death, Friedrich is notable for being a hotbed of activity by the SS Raven Division from the Nazi-dominated parallel Reich-5, who seek to turn his Holy Roman Empire into a First Reich and breeding ground for Aryan warriors. Frederick in a 13th century Chronicle Friedrich I. von Hohenstaufen (1122 – June 10, 1190), also known as Friedrich Barbarossa (Frederick Redbeard) was elected king of Germany on March 4, 1152 and crowned Holy Roman Emperor on June 18, 1155. ...

Gallatin

Gallatin is named for Albert Gallatin, the dominant member of Thomas Jefferson's government in the absence of Alexander Hamilton. Without Hamilton to defend and explain the Federalist Papers, the U.S. Constitution of 1787 was never ratified and the independent colonies Balkanised into nine separate republics across the continent by 1860. In "current year" 2004, Gallatin's great powers include Texas, German-dominated Europaverein, the British Empire, the Soviet Union, and the Japanese Empire, with the peace maintained by the fear of mutual destruction in an atomic war.
