Awesome Expeditions Through Uncharted Territory!

It is said it is the journey rather than the destination which is more important and Achtung! CthulhuUnexplored fills in the blank spaces on the map, agents often simply “redline” through before their next epic encounter.


No corner of the globe is safe from the unholy alliance of cultists and the Mythos, and agents should be prepared to traverse all kinds of dangerous terrain to carry out their assignments. 

From the dark depths of perilous caverns to the sweltering jungles of the tropics, from the peaks of snow-capped mountains to the merciless sands of the desert, Unexplored allows you to traverse six separate biomes, randomly generating missions, challenges and adventures, with exciting expeditions through unknown territory.

Create endless forms of wilderness adventure, either on the fly, in preparation for a game session, or as inspiration for adventures of your own. 

Discover how weather, hazards and environmental conditions will affect each expedition, explore creative uses for Threat, detect new NPCs and deploy dangerous denizens like panthers, cougars and alligators! 

Each chapter concludes with four detailed locations with a main mission and a host of adventure seeds to use as the climax for each journey, or provide an entertaining diversion along the way. 


This 144-page, full-colour, softcover book features:

  • Full rules for wilderness traversal, supplies, weather, and survival
  • Six challenging biomes: Caves and Caverns, Deserts, Forests, Jungles, Mountains and Hills, and Plains
  • Unique events, challenges, and encounters for each environment
  • Hazards, terrain, easter eggs, and even special effects unique to each biome
  • Detailed mission locations and adventure seeds for every biome!

The threat of Black Sun, Nyarlathotep, and the Old Ones can’t be ignored, yet from the highest peaks and deepest oceans crawl a myriad of new terrors awoken by this terrible conflict. We must be vigilant, and that means taking the battle to those little-explored places!

Requires the Achtung! Cthulhu 2d20 core books to run.

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.
