More About Achtung! Cthulhu

Discover the secret history of World War Two - stories of the amazing heroism which struggled to overthrow a nightmare alliance of science and the occult, of frightening inhuman conspiracies from the depths of time, and the unbelievable war machines which were the product of Nazi scientific genius - and how close we all came to a slithering end!

Play a huge range of classic wartime heroes such as Russian political officers, German U-Boat commanders, British commandoes, RAF pilots, US rangers, Washington investigators, London journalists, Hollywood starlets, and resistance fighters from all across Europe, who must all unite in the battle against the darker side of World War Two. Play a full campaign leading from the opening shots of the War in 1939, through intrigue and adventure in Occupied Europe, the siege of Berlin in 1945, and finally the cold wastes of Antarctica in 1946!

Featuring stunning art by illustrator Dim Martin, each Achtung! Cthulhu release will be packed full of evocative and inspirational scenes and is designed to be a totally standalone product letting you jump right in to tentacle fueled wartime adventures! 

Written for the popular Call of Cthulhu roleplaying and Savage Worlds games, Achtung! Cthulhu will thrust your characters in to the midst of a dark and desperate struggle, as Cthulhu's minions take advantage of the chaos wrought by the Third Reich to topple civilization! The massive world-spanning Achtung! Cthulhu setting features occult conspiracies, terrifying Nazi war machines, and an ancient evil so powerful that it threatens to tear the world apart!

My copy is missing some numbers on the map of the Castle. The numbers 6 and 10 are missing. Is this a typo? Can I get an update or corrected page?

I guess Modiphius will never answer this and the map remains broken.

What happened to the non-revised version of this? is it not offered as a standalone thing anymore? I think it was in one or two bundles, but why is it not still available as a standalone thing? It is probably not too big a deal either way, but I would like to know.

Also, is there an estimated release date for the noted adventure "Code of Honour" at this time (either for Realms of Cthulhu or the true Achtung! Cthulhu setting, or both)? And will there be more adventures in this campaign?

However it goes, I look forward to future output from this setting and related works.

The non-revised version is here still:

We have the art ready for Code of Honour, just waiting on Sarah Newton finishing the writing, it's close but please encourage her :-) Yes she does plan more adventures in that series. For other big adventure series see Shadows of Atlantis

Oh. Alright, I guess I keep forgetting about DriveThruRPG. I actually prefer this site for the incredibly petty reason of I like its color scheme better. I guess it just seemed strange that it wasn't on this site, but is on that site.

No big deal, and thank you for your prompt reply. I believe I got the item through a bundle anyway.

I am a little confused. As an owner of Three Kings, what is in the revised edition that would make me want to spend $10 to purchase it a second time?

If you own it already you can download the updated version for free via your DriveThru RPG Library. Just sign into your Account and check your Library, the new content will be there.

The revised edition brings the Three Kings material in line with the Keeper's and Player's guides plus I'm pretty sure it brings some small tweaks to NPC's and the pre-generated characters...

I purchased Achtung! Cthulhu: Three Kings - Savage Worlds, which shows in my library (and was not recently updated). The product above is a different listing. Generally, when a product is updated, a new listing is not created (a new file simply replaces the original). In this case, the Revised Edition requires a new purchase and I am curious as to why.

Chris B June 21, 2014 2:15 am UTC
We're not changing the original listings Joseph as they're for stand alone versions of Three Kings that don't require the Keepers & Investigator's Guides. This is a new version so people can choose which they want. However you should have received a code to download this for free - everyone who purchased this is getting it for free through our site, Kickstarter or RPGNow/DriveThru. If you haven't received the mail please check if your privacy settings are set not to receive emails as that may be why you've not had it, let us know :-)

Hi Chris, I've had only a cursory glance at both editions side by side, and I can't for the life of me find a difference. I received a mail, and i see links to updated downloads, but they still appear identical? A couple comments have stated that the revised is more in line with the IG and KG, but I'm not seeing a difference. unless somehow I've just re-downloaded the old files, but there's nothing else available unless I checkout with a $9.99 price tag? Sorry, confused and feeling dumb :) Is there specific info on what's different somewhere? cheers!

It seems a shame that those who supported the Kickstarter and purchased the original Three Kings now have to pay $9.99 to get the revised version.
Customer avatar
Chris B June 20, 2014 3:06 pm UTC
Kickstarter supporters are also getting it free Robert! Just uploading the file and sending the update!
Customer avatar
ROBERT D June 20, 2014 3:08 pm UTC
Then please accept my apologies Chris for jumping the gun on this.
Customer avatar
Chris B June 20, 2014 3:10 pm UTC
No problem - with several places to update at once not everyone hears immediately!

File Size:

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.
