Alternity Core Rulebook

Watermarked PDF

Strange new worlds and deadly aliens? Mercenaries for hire? Post-apocalyptic survival? Explore your favorite visions of sci-fi adventure in the new Alternity Science Fiction Roleplaying Game from Sasquatch Game Studio. Alternity is a sci-fi roleplaying game system suitable for a wide range of genres. Designed with modularity in mind, Alternity campaigns can be set across the spectrum of sci-fi genres: from hard sci-fi to space opera, or post-apocalyptic wastelands to alien conspiracies.

The Alternity Core Rulebook features a modular toolkit that you can use to build great characters and adventures in your favorite sci-fi universe—or in a universe of your own creation. It starts with the Alterntiy Core Rulebook, which covers character creation, futuristic technology, and adventure design, and includes a selection of dangerous aliens and villainous adversaries, as well as guidelines for building the universe that you want to run. Inside you'll find:

  • Six species, seven archetypes, skills, and special talents to build your science fiction hero.
  • A fast-paced combat system perfect for bringing cinematic action scenes to life.
  • All the hazards, set-pieces, and adversaries a game master needs to create sci-fi adventures.
  • Campaign design guidance, discussing genres and tech levels.
  • Dozens of ready to use adversaries, and quick rules to make your own.
  • And much more!
If you want to take a look at the rules, check out the free Alternity Quickstart Guide in the Alternity Demo Pack.
The Alternity Core Rulebook is the first product in the Alternity line, and upcoming releases will add even more options to your Alternity game. Be on the lookout for:
  • Protostar Mission Guide: An introduction to the hard sci-fi Protostar campaign setting with a series of adventures that explore the worlds beyond the wormholes of the Protostar Nexus. In the 23rd century, governments and corporations vie for control of the corridors between our solar system and the resources of the worlds beyond the gates.
  • The Shipyard: Starships for all tech eras, with rules for crafting ships and building characters to pilot them.
  • Xenologist's Guide: Even more adversaries and aliens to populate your campaign and antagonize your heroes. Plus rules for building PC species and expanded rules for creature creation.
  • Dark Nebula Mission Guide: An adventure series set in the Dark Nebula campaign, a far-future setting in which slowly decaying, milennia-old empires clash while distant stars are being extinguished by some unknown force.
About Alternity: In 1997, Bill Slavicsek and Richard Baker created the original Alternity game - a tabletop RPG engine for science fiction adventure across a wide range of genres. Now, twenty years later, Richard and fellow Sasquatches David Noonan and Stephen Schubert have created a new sci-fi RPG inspired by the original game. We've rebuilt the game mechanics to take advantage of 20 years of advancement and experience in the art of game design. A crowdfunding success, the Alternity line includes a number of upcoming supplements: the starship focused Shipyard; more aliens and adversaries in the Xenologist's Guide; the campaign setting/adventure series of the Protostar Mission Guide; and more to come!

I went to your website and saw the Voyager - Complete PDF Bundle for sale. Is that only available to Kickstarter backers? I doubt it since it let me add it to the cart. But it charged $8 for shipping & handling. For PDFs. Is that a glitch? If you could get back to me I'd appreciate it. Thank you.

I am disappointed that there aren't any rules for ship vs ship combat in the core book. Considering the game's pedigree I'm surprised. When will the Shipyard book be coming?

I just picked up the hardback. The system is workable and the basic rules make it possible to run campaigns in several different settings. It will benefit from future world-books, however. There are a few sci-fi tropes that either aren’t covered or aren’t given a very deep treatment (Mecha, alternate dimensions, cybernetics). That’s to be expected, though, and overall, I am very happy with the product.

I'm gradually going through the pdf, and to be honest the layout could be better...headings for a subject at the bottom of a page is the most obvious one atm.....that's after a brief perusal.

Will there be a Conversion Guide for previous Alternity characters, etc.?

Any word or idea if there will be a dead tree version at some point? I dislike going purely digital if I have the choice but thoroughly loved the original Alternity back in the day.

I don't know if they plan to sell them through RPGNOW, but hardcovers already exist; some people got to buy them at GenCon, and they're on their way to those of us who Kickstartered the game for the most part.

I bought this product on a whim, because I liked the original Alternity - owned every book of the line - and was curious.
As far as I can tell, it delivers on the designer's promise: To provide a modular game system that can be used for all sorts of science fiction. The mechanic is a polished version of the original Alternity, layout is easy on the eyes and the entire book is well written, providing hints and tips where you expect them and when you need them.
Artwork, while sparse, is of decent quality and does not get in the way.
Overall, a nice product and a good buy.

how good would you say it is at running previous edition campaigns?

I have a suspicion this one has better mechanics but the older ones better lore and adventures...

I'm a kickstarter backer and already love this book. The pages are good for people whom have a hard time to see due to near blindness and the system is polished compared to the old one.

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.
