A downloadable TTRPG

Buy Now$15.00 USD or more

Hey, folks! Rainworld and all of its expansions are currently in a bundle: itch.io/b/824/save-tks-teeth-bundle to help out another RPG creator. If you're thinking of buying a copy, please check that out!

My first and flagship game, Rainworld is in many ways a love letter to janky early-90s rules, dystopian SF settings, and dad jokes disguised as flavour text.

Catgirlspersons! Psionics! Biotech combat androids! The gig economy! A cyberpunk gear list with as many evening dresses as shotguns! Six Seven pamphlet-sized supplements for it already!

The internet's finest* dystopian cyberpunk McJob TTRPG!

(*according to: me.)

Two centuries into terraforming the New Republic of Libertaria, the planet is nice enough — well, liveable enough — as long as you live within a few dozen klicks of one of the sky-high toadstool-shaped atmospheric processors. And lucky you, you do, in the urban sprawl around the base of the New Shenzen processor. The daily rains are a side effect of terraforming — should calm down in another few hundred years. The main thing is, your ancestors escaped from the Commonweal's long nightmare of peace and prosperity to found a society based on the real principles of real men — the capital-F Freedom to sell yourself into indentured servitude, own a different military assault weapon for every day of the year, and die from a minor infection because actually seeing a doctor is a deluxe premium optional extra for your medical insurance.

Breathing the air is still free at point of use, but trust me, they're working on it.

Rainworld is currently in development — the art isn't all there yet, and there may be remaining typos. (Tell me about one, and I'll credit you for proofreading!)

Rules plugins:

A set of pamphlet-sized expansions to the Rainworld rules is underway.

Currently available:

  • Cyberdeck — cyberpunk hacking rules

  • Toxcrawl — wilderness exploration in the toxic apocalypse beyond the atmospheric processors
  • Catwalk — expanded gear and fashion to keep your operative on the cutting edge of style
  • Draculoid — simultaneously a joke and a supplement you can run entirely seriously as part of your Rainworld game (yes, really): Dracula for Rainworld!
  • Control — more sample RFWs, the Department's inner workings, Rainworld's calendar, and guidelines for naming Rainworld's places and people
  • Offworld — expanded character creation options for characters originating in the wider Interstellar Commonweal

I'm still making my way through the rulebook but
1) Could I play this through discord? Or do we have to be in the same room?
2) There's no GM for this game, right?


It's designed for a GM - the role that the rules refer to as "Control".

The combat rules are maybe a little bit crunchy, as written, to run entirely without a map grid - but if you handwave the weapon range rules, there's no reason you can't run it as pure theatre of the mind. (I certainly don't see a problem running it unmodified in something like Roll20.)

Thank you so much for the quick reply and clarification!

No problem!


Er... There's already a game called Rain World.


There is indeed a platform video game named "Rain World", which has no connection with this pen & paper RPG named "Rainworld". I hope that clears up any confusion you had!


I wasn't confused, I was pointing out that it might cause other people confusion.




These rules have such a great section on safety that I'd like to ask if I can re-use it verbatim, with credit, in the RPG that I'm planning on releasing.


What, really? Sure!


Thanks - much appreciated. I'll drop you a line when it's out.


Cheers! 👍
