24XX is the free version of the rules used by the 2400 series of RPGs. The SRD is released under a Creative Commons Attribution 4.0 license. Materials include:

  • Plain text system reference document (SRD)
  • PDF versions for layout reference
  • Affinity Publisher version for use as template
  • Vector logo usable in 24XX compatible games
  • Google Sheets version for use as template

24XX games prioritize description and narrative positioning over detailed rules processes, taking the highest die rolled over mental arithmetic, and polyhedral dice over only one shape of die (because funny-shaped things are fun to roll). While 2400 is a sci-fi series, you’re welcome to use these rules for whatever setting you like. And if you use any of this material in your own games and hacks, please get in touch to let us know!
