Infinite worlds cover

There are hundreds or more alternate worlds in the GURPS Infinite Worlds multiverse. Most of GURPS settings can be easily adopted as part of the Infinite Worlds settings which includes Infinity Unlimited. Note that GURPS 4e (2004) is not entirely consistent on how it uses the "^" (superscience) notation and "^" didn't exist in GURPS Classic at all. This coupled with changes in the GURPS TL scale means that TLs from sources before 2004 may not be at the same TL in 4e.

Random Generators for GMsEdit


Sourcebook names abbreviationsEdit

There are also references to Atomic Horror (AH), Atlantis (AT), Banestorm (BA), Black Ops (BO), Camelot (CA) Dragons (DR), Fantasy for 3rd Ed (F3rd), Fantasy II (FII), Goblins (GB), International Super Teams (IST), Reign of Steel (RS), Steampunk (STM), Terradyne (TE) and WWII:Weird War II (W:WW). See the official Steve Jackson Games Abbreviations for GURPS Titles page for details. Books not abbreviated on that page have been cited under their full titles.

Additional informationEdit

Timelines are listed by quantum. The number known is the number of timelines known to Homeline. Some timelines have moved quantum and a few even changed "local present" in 4th edition; those with only Classic sources are marked with "*". Tech Levels for uninhabited worlds are listed "NA". Due to the changes in Tech Level between Classic and 4e the TLs for 8+ from Classic material is not quite right. When possible the TL is updated to 4e (using the lowest TL possible) and in bold.

This topic is based on the lists formerly posted as Timeline Map for the Infinity Unlimited Campaign and Timeline Map, Infinite Worlds Wiki both of which are preserved thanks to Internet Archive. It is being updated to bring it in line with the GURPS 4th edition Infinite Worlds book and subsequent releases.

The number of realities for Classic and 4e is listed on the Known Realities page.

Some additional details regarding some of these worlds can be found at

Important note on the yearsEdit

While the present for Homeline is roughly the same as ours (23-24 years from the relevant book's present and the same present as Merlin-1) most of the worlds haven't haven't seen the relevant number of years pass for them (Alternate Worlds 1 and 2 still have Homeline's present at 2015).

For example, Cherokee is still in 1930 and Holly is still in 1989 despite Merlin-1 keeping up with our present.

Three other issues are when Centrum discovered Homeline, when Homeline learned of Centrum; and Centrom-Beta which lost 15 years going from 1910 to 1895. These three things are the "smoking guns" confirming the Homelines of Classic and 4e are different though very similar.

One can easily hypothesize a Homeline-2 as representing the Homeline of Classic.

Worlds that have the same year in Classic and 4e are in bold.

Note 1: 12 listed above.

Note 2: Known generally as "Deadly Settings", "Reality Vanish" or just "Vanish ", there are at least 41 parachronic coordinate settings where people or objects sent into them never return. These are assumed to be worlds where the laws of physics are sufficiently different from that of our own universe to kill visitors and/or cripple their equipment (IW141).

  10. Time Travel p. 89
  11. It was established in GURPS Alternate Earths 2 111 that 1902-1912 was when Centrum's last war was.
