The year is 3200 and mankind's empire lies in ashes.

The Jump Gates fell six hundred years ago, severing the links between the myriad worlds of the human diaspora.

Now, the long isolation of the Silence falls away as men and women return to the skies above their scattered worlds.

Will you be among them once more?

Stars Without Number: Revised Edition is an old-school-inspired game of sci-fi adventure, one built from the ground up to encourage sandbox play and simplify a GM's job in providing it. Familiar mechanics are employed to forge new worlds and explore new possibilities, guidelines built on long experience used to help a group venture in wholly new directions. Within the full-color pages of Stars Without Number: Revised Edition, you'll find… .

  • Backwards compatibility, as the Revised Edition is built to work cleanly with existing Stars Without Number supplements and materials. The new systems slot in smoothly, and you can take or leave them individually as your group prefers.
  • Expanded character creation, with PCs now customized by special talents and character foci, new options for psychic characters, and new ways to make your hero mechanically distinct. Yet the process is still smooth and quick, with a special quick generator spread to create a hero from nothing more than a half-dozen die rolls.
  • Refined psionics, with more options to distinguish your psychic hero's powers and more flexible choices for their abilities. Tailor your psychic to your concept, whether as a cynical gunslinging brainguard or an ascetic psychic healer from a world of austere psionic scholars.
  • Improved starship combat, with decisive roles for every member of the party. Build your own starships with the included system and employ new hardware and new starship mods to make your ungainly crate the fastest contraband runner this side of the Veil Nebula.
  • New systems to support additional types of play, including rules for hacking, remote drones, and expert technical modification of gear and starships.
  • Upgraded tools for sandbox sector creation, with forty new world tags to help define a GM's stellar creations, guides for adding additional system points of interest, and material to help a GM define the interesting traits of the worlds they create. These tools aren't just a clump of random tables, they're a framework to boost your own creativity and help you make fast, good, playable material for your game.
  • Augmented adventure creation guidelines. Aside from a hundred piping-hot adventure seeds that mesh smoothly with the world creation tools, Stars Without Number: Revised Edition also includes content to help you turn your vague ideas into a playable evening's adventure. Guidelines on challenges, rewards, and complications in play are all aimed toward the working GM, the man or woman who's not just theorizing their adventures, but actually responsible for making something fun for the whole group.
  • Tools for creating aliens, Virtual Intelligences, and hostile human foes, with guidelines for handling potentially-hostile encounters and creating the kind of fearsome xenobeasts that can challenge the doughtiest explorer. Or perhaps you want to be an alien or robot? You'll find the tools for that in Stars Without Number: Revised Edition.
  • Faction rules, for handling the background warring and intrigues of hostile groups. Need to add life and motion to your stellar sectors? Sprinkle in a few factions to make news for the PCs to respond to, or use these rules to handle the colonies, spy agencies, mercenary companies, or other enterprises your heroes establish.

And these things? They're all in the free version. Yes, just like the original edition, Stars Without Number: Revised Edition has a free PDF edition to share with your friends and pass around to interested parties. Those daring stellar freebooters who purchase this deluxe version will get...

  • Transhuman tech, with rules for bodyswapping, digital identities, post-scarcity economics, and just as importantly, GM guidelines on making exciting adventures when all the old pillars of familiarity have fallen away.
  • True AIs, the vast and terrible intellects that can bring forth wonders and ruin in equal measure. Playing a synthetic VI or aspiring organic godmind? Learn how your PC can accumulate the tech they need to ascend to this new plane of being.
  • Mechs, for those GMs who relish the thunder of steel titans on their far-future battlefields.
  • Heroic PCs, for groups that want to trade the gritty, lethal tone of a standard campaign for classic space opera, with larger-than-life heroes and superhuman skills.
  • Society creation, customizing a world or a hab with its own culture and history, pre-designed with fault lines and conflicts to engage your heroes. You'll get more than a dry recounting of details; you'll get the information you need to build adventures that fit with this world's smouldering tensions.
  • Space Magic, with rules and guidelines for introducing sorcerous powers and old-school magic into your starfaring adventurers, with sagacious Magisters, versatile Arcanists, and Adepts graced with supernatural powers.

So leap forward, brave adventurer! The stars await you, and the wild glories of an untamed sky!

Has anyone tried to re-create the Therian factions from AT-43 using these rules? I was looking through the Phone version and couldn't find stuff like "optical holoflage" or "nano-munitions" as described in the AT-43 books so I'm looking for inspiration from the tinkerings of others.

maybe a dumb question but why does the book stipulate that nukes are useless in ship to ship combat?

maybe a dumb question but why does the book stipulate that nukes are useless in ship to ship combat (page 102)?

Because there is no fire in space and ships are designed to protect from the void, so keeping out radiation from a nuclear blast is easy.

The radiation from a nuclear blast is several orders of magnitude greater than the normal background radiation of space. Even if the ship survives the blast, there is a fair chance that the crew got lethal radiation poisoning.

Here's more info than you'll ever want to know about nukes in space:

By the way, is an amazing source of free information for anyone who wants to run realistic sci-fi games.

Is there a list of pre-made adventures for SWN Revised edition, available?
Customer avatar
Jeremy H March 07, 2022 2:57 am UTC
I remember a lot of people used the original edition (1e) of SWN for fantasy campaigns. Have any of you attempted a similar campaign with 2e? Which do you recommend for a really diverse campaign (lots aliens/races, etc.) SWN (2e) or WWN? Also, are Kevin's books A4 or Legal sized? Thanks in advance.

Where can I buy the physical Original Edition book? The physical Revised Edition one is too expensive, I'm looking for a cheaper one to buy. Thanks.

Do note that it's strictly paperback now. You can no longer buy the hardcover version.

Nice game!
But, I can't find an answer to my question. Does Fray Die roll affect NPCs' hp or hit dice?

Jordan B January 04, 2022 6:49 pm UTC
its from "Worlds without Number" which is the fantasy version of Stars without number but its what I had open so...
"Once per round, as an On Turn action, inflict 1d8 damage plus your level to any one target within reach of any of your Readied weapons, provided they have equal or fewer hit dice than you have levels. This damage is not modified by any ability or bonus, and can affect any creature who could be hurt by that Readied weapon."
This implies it goes to HP to me and not hit dice. Otherwise a warrior would be able to knock out a bear as an incidental if he was level 6. Level 6 guys are tough but not *that* tough. I think only Scarlett heroes uses the hit dice damage system.

adding classes in the deluxe edition that require spells, and then not including spells in the book, seems a bit misleading. you're giving us classes, sure, but they're impossible to play without going out and finding other books to get spells from.

Could someone give me and example of how the magic works in this?
I'm trying to find a system with high gear customization and a robust but not overpowering magic or psionics.

I'd recommending perusing the Free edition. The full PDF you can purchase here has additional rules but the full Psionics class is laid out in the Free version.

Quick example for psionics:
I pick the psi-focused class. Get 1 free point worth of one of the psi skills: healing, precognition, etc. I pick Teleportation. That gives me a basic ability: "Warp 10 meters". With my starting feat-equivalent (Focus) I take an upgrade that gives me more mind power, and put that into the same ability. For hitting level 1 (starting at 0) I now also get a free power besides boosted range. I pick "Warps of under 10 meters are free and are a move action". Instead I could've picked "the warping power can be used as a form of omni-directional vision".
The powers run on Effort, a very small pool such that using any ability usually requires "committing effort" during use/for the scene/for the day. For Teleportation it's "for the scene", and with my starting Effort pool of 2 that means two teleports per scene, enough to be cool and useful but not a constant ability. The upgrade makes short warps free and fast, significantly changing...See more

I'm looking to run a game that is similar in human development to the Expanse, but with my own homebrew setting. Would the mechanics of this system fit?

I see now you're asking about the deluxe-exclusive charts, my mistake. There's about 25 tables of society variables split up across origins, rulership, and cultural flavors. Permutation set exceeding 9.28789 x10^23

The hardcover “Deluxe Edition” is wonderful, with a solid binding. It’s a fair size that will impress.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
