Achtung! Cthulhu 2d20: The Stuff of Nightmares (PDF)


Trapped Inside Your Own Mind!

It is July 1941 and several brave Allied agents awake inside an underground research facility in central Europe, tied to chairs, with no idea how they got there and even worse, no memory of the past two weeks. 

So begins a virtual nightmare as the agents escape their confinement only to experience a series of strange circular events, ghostly apparitions, non-existent rooms, and corridors that endlessly turn back in on themselves. 

Escape seems impossible as they are caught in a repeating loop which makes no sense. 

Only by gathering clues and evidence, talking to fellow prisoners and putting together the disparate pieces of this psychological puzzle will they learn to navigate this strange new reality.

But even then, after they discover the truth about their unusual imprisonment, they still face several daunting challenges. 

Can they counter a powerful ritualistic spell to break their captivity, and foil a plot by the loathsome Reiner Lang, Prior of the Black Sun? Can they escape from this living nightmare, or, with time running out, will they finally succumb as a powerful mythos entity begins to feast on their minds?

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.
