Alien Bestiary (Starfinder)

Watermarked PDF

It Came from the Stars!

The Alien Bestiary brings you an incredible array of sci-fi and space-themed monsters and menaces for the Starfinder Roleplaying Game! The creatures you’ll find within are perfect for whenever your heroes venture into the dark tapestry of space or have to defend their homeworld from alien invasion by eldritch horrors from beyond the stars, whether you use the official Starfinder setting, a universe of your own design, or a dedicated sci-fi saga like the Legendary Planet Adventure Path or in the Aethera Campaign Setting!


You’ll find allies and adversaries within these pages, from playable races for your sci-fi game to cosmic horrors and apocalyptic enemies inspired by classic themes of science fiction. This volume collects nearly 300 monsters from CR 1/2 to CR 30, including template grafts and starship-level creatures from tier 4 to 18. You’ll find residents of the Legendary Planet and Aethera settings, Starfinder versions of classic creatures like the myrmidon robot, plasma ooze, and star-spawn of Cthulhu, alongside brand-new never-before-seen monsters like the asteroid worm, star fairy, meteor dragon, and supermassive singularity!


The Alien Bestiary is more than just monsters too, with appendices devoted to cults of the Great Old Ones, creatures of the Aethera system, creature indices by type and CR, high-tech traps and hazards, and spells, feats, and expanded rules for aetherite radiation, vacuum, and more! The PDF version, of course, is hyperlinked and bookmarked for your convenience, and the book is packed with incredible artwork and delightful design by some of the best authors in the business. These monsters are dynamic and cinematic in how they play at the table, with ecology, history, and lore that are a pleasure to read.


Don’t let your Starfinder Roleplaying Game campaign get lost in space or just be a trek among the stars! Grab a copy of this incredible 448-page monster accessory today and Make Your Game Legendary!

QUESTION: Are community content creators allowed to use the monsters in your book in their published adventures (giving credit of course)!

This is a fantastic book to own in both print and PDF (print is available at Legendary Games' website). A must have for Starfinder GMs. I have my PDF here but for some reason no option is being given to leave a review, so posting here.

I figured out I can't leave reviews as a publisher, so here's my off-site review:

I'm really disappointed that almost every piece of art is republished, except for a few. I know it's expensive and time-consuming to make, but it's a major blow when one of the main appeals of these books is the art.

Art is expensive. If the authors were to commission every piece of art, they would be losing money in putting this product out.

Also wondering if there will be a Print On Demand offering in the future.

We are doing a traditional print run of this book, with the books expected to arrive probably in November. You can preorder the print book or print/PDF bundle at the Legendary Games webstore.

Not sure if it's made it through to the final version, but the Change Shape entry for the Aboleth Veiled Master in the Full-size preview just has the definition of the Change Shape ability, with nothing to indicate what this particular monster can change into.

Thanks for letting me know. I'll double-check that with layout before the final print files are approved.

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.
