Welcome to Gathox Vertical Slum, a far out, gonzo science fantasy campaign setting for Swords & Wizardry White Box Edition and other classic tabletop role playing games.

Aliens, mutants, spellslingers, and hardened criminals struggle for dominance in a lawless city built upon the back of a wandering, world-hopping godling. Inside this tome you’ll find:

* A fully mapped and fleshed out Vertical Slum, stuffed to the gills with greedy factions, hook-laden NPCs, and seedy locations.

* A new gangland system for running domain-level games at level 1.

* 43 fully illustrated strange and inimical monsters to spring on unsuspecting players.

* New classes, skills, ability checks, hirelings, and gear for players to work their will across the mean streets of the Great Spire.

* A vertical dungeon introductory adventure to test the skills and resourcefulness of new and seasoned players alike.

* Over a hundred lavish interior illustrations by D.L. Johnson.

* Five pieces of interconnected chapter fiction contributed by Josh Wagner.

The Chapter 2 maps of each area (pg.16,26,36) are low quality - can't read the street names very well for the Kettle and Favela. Are there higher quality versions available?

Hi Schtt, this is Dave, the creator of Gathox! I still have my highest-res files for each of the maps, if you email me at:, I can email you the files I have. Hopefully they'll be high enough resolution for your needs! Cheers and thanks for your support!

Will there be a hardcover version?

Thanks for the question, Thilo! As of right now, we haven't planned on a hardcover version. We've had some talk about doing a deluxe hardcover edition down the road after we've released more modules for Gathox. The next module, "GVS2: Quake Alley Mayhem!" is designed for tournament play and will be out in March! Cheers!

Agreed. This edition will stay softcover, but a hardcover edition may very well be in the future.

Yes, the POD is in the works! Mike Evans is proofing the print files as we speak, should be in a couple weeks. Also, anyone who buys the PDF will get an equivalent discount emailed to them off the price of the bundled POD when it drops. Thanks for the comment!

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.
