Hull Breach Vol. 1


Brace for impact with the premier module anthology and sandbox campaign setting for the Mothership Sci-fi Horror RPG 1e. Eclectic yet intertwined scenarios, locations, toolkits and terrors.

Hull Breach Vol. 1 is a massive collection of 26 adventures and supplements spanning over 200 pages of all-new content, brought to you by a killer international crew of 3rd party Mothership authors, designers and artists. It’s everything you'll need to run Mothership 1e for years to come!

“Hull Breach is a stunning achievement by an insane team of creators. If you're a fan of sci-fi horror, I think this is one you can't miss.”

  • Sean McCoy (Mothership)

“One day I’ll run a Mothership campaign, and I can’t imagine doing it without this.” 

  •  Johan Nohr (Mörk Borg)


Curious about what’s inside? Let’s take a look at a few Hull Breach modules:

Manhunt by Ian Yusem (The Drain)
A Mothership system hack where you play the aliens! All new classes and rules for running creatures from beyond the stars, pitted against monstrous human foes.

Vibechete! by Joel Hines (Desert Moon of Karth)
Corporate scions party their last aboard an abandoned luxury space station in this twist-filled slasher adventure! 

Residue Processing by Daniel Hallinan (Bloom)
Run hapless test subjects through a sinister artifact experimentation gauntlet in this Portal-inspired funnel adventure, for science!



To help you find precisely what you need on game night, we’ve divided the book into 5 convenient chapters:

  • INTEL: Level up your Warden skills with essential toolkits, mechanical innovations and theory columns from veteran horror GMs.
  • MISSIONS: A thoroughly playtested stable of adventures ready to rock your next one-shot or re-fill your seasoned crew’s job board.
  • LOCATIONS: Stations, planets and more to vibrantly populate your campaign world.
  • ENTITIES: Drop-in NPCs and extraterrestrial horrors to stalk your players’ dreams.
  • ASSETS: Loaded for bear with cassette-futurist tech, weapons and survival gear.
Though explicitly designed and statted up for Mothership 1e, Hull Breach contains plenty of resources and content applicable to any sci-fi RPG. No matter how you play, Hull Breach will work for you!


But that’s not all. There’s a secret book within our book, an invisible world lying just beneath the surface. Hull Breach articles weave an interconnected web of hooks, rumors and crossovers dangling for players to tug upon. 

Appendix materials like our sector map, conspiracy board and corporate factions outline an expanse of space dominated by the Publico megacorporation, and arm you with tools to effortlessly run a campaign therein.

It’s a complete campaign package when you need it, and an eclectic assortment of shiny toys when you don’t.



Our extensive digital asset pack includes printable handouts, tools and resources for online play, plus VTT-ready maps, tokens and more.

We also created an online planet generator based on a Hull Breach module as a companion website enabling interstellar exploration-based play. Our Rimspace Planet Generator won a Gold ENnie for Best Aid/Accessory (Digital) 2023.

Printed in Canada with extravagant paper stock, cover treatments and book ribbon.
Fully hyperlinked, bookmarked and screen-reader ready PDF included.

This book is amazing. First It takes some time to find your way through it, since there is a lot of stuff, ready to go missions, modules etc. When you know where to find what, you end up with a whole metaplot to play.

There's a lot going on with this book etc and it's beautifully done. I can honestly say that the extras and physical products that came from the kickstarter are some of the best I've seen. It's smashing. They said they have some overruns for sale from the original print run and I cannot suggest it more strongly.

And Breach of Contract is just freaking brilliant. Very, very, very satisfied <3

This book is easily the best RPG supplement I own. The content is all captivating while also managing to be extremely playable. The art quality is also supreme, I haven't looked at a single piece of art and thought "they cheaped out on that one".

I backed this on kickstarter and am very impressed with the entire project. The book itself has a juicy anthology feel, and the extras like maps and planet generator just show their commitment to terrifying me in space. Great stuff.

I was an early backer of the kickstarter and am thoroughly impressed with the product. There are oodles of things to help not only Mothership game masters, but any sci-fi space related game. I particularly enjoy the artwork and design aspects. They help tell the story alongside the author's writing.

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.
