Direct the course of the new Secret War!

 Welcome to the Secret War in this fast-paced pulp-influenced rollercoaster of an RPG that nimbly mixes the sanity-challenging terror of Lovecraftian cosmic horror, with the chaos and heroism of World War II. 

As a gamemaster you will bring to life this pulp-influenced world of brave Allied heroes and dauntless two-fisted adventure, guiding the heroic actions of players while also directing the twisted might of the Nazi occult: the Cult of the Black Sun, who wield foul magic and summon captive horrors and Nachtwölfe, their rivals who place their trust in Atlantean technology, weird science, and strange wonder weapons. 

You will shape a world where dread secrets and powerful artifacts lie forgotten in ancient ruins, where dusty tomes are replete with eldritch knowledge, and you’ll arm players with experimental technology, deadly weapons, and powerful magic, to do battle with this uncanny threat. 

You’ll bring to life exotic races like the Deep Ones, undersea worshippers of the dreaming god Cthulhu, or the strange Mi-Go, fungoid-insectoid beings who have come to Earth for an unknown purpose. You’ll also control the sanity-sapping monsters, entities, and gods of the Mythos themselves, who seek to take advantage of the chaos of the second world war to extend their dominion over the minds of men. 

Will your players prevail against all odds, or will they, like so many others before, fall to the malign influence of the Mythos? That is your story to shape and tell… 

Inside this Gamesmaster's Guide 260+ page full color US Letter sized hardback you’ll find: 

  • Dedicated advice on the art of gamemastering including managing the game economy and specific tips for creating memorable characters, adventures, and campaigns to thrill and delight your players. 
  • Major new lore and detailed background information on the six major factions contesting the Secret War: Section M, Majestic, Black Sun, Nachtwölfe, the Deep Ones, and Mi-Go including their backgrounds, history, hierarchy, secret bases and missions, and goals. 
  • A vast repository of hidden lore and forbidden magical knowledge including new Mythos books and tomes, powerful ritualistic magic, plus the damnable spellbooks of Nyarlathotep, Yog-Sothoth, and dread Cthulhu himself! 
  • Arm your players with a wealth of new weapons and espionage devices from secret government labs and classified research departments with the Secret Weapons of the Secret War chapter. 
  • Complete profiles and statistics for the powerful heroes and villains of the Secret War, the men, and women who do battle for the fate of mankind, plus a huge bestiary brimming with all the terrifying gods, monsters, and entities of the Mythos themselves.

You'll receive a FREE GM's Guide PDF right away. 

NOTE! The Achtung! Cthulhu Player's Guide contains the full core cinematic 2d20 rules for actual play and you’ll require that to play the game.

What is Achtung! Cthulhu?

Achtung! Cthulhu is a setting for Lovecraftian roleplaying during World War II, which allows players to discover the truth behind the malign influence of the Mythos on the Nazi war machine and beyond, as conflict engulfs the globe from 1939 to 1945.

In this pulp-influenced world of brave Allied heroes and dauntless two-fisted adventure, players will take on the roles of Allied servicemen and women, secret agents, members of the resistance, or even hapless civilians caught up in the wider conflict. All stand firm against the twisted might of the Nazi occult: the Cult of the Black Sun, who wield foul magic and summon captive horrors in their bid to unleash Yog-Sothoth and Nachtwölfe, their nominal allies and rivals who place their trust in Atlantean technology, weird science, and strange wonder weapons to prevail.

Players will experience a world where dread secrets and powerful artifacts lie forgotten in ancient ruins, abandoned sites, and forgotten cities, and peer deep into dusty tomes and manuscripts seeking to understand eldritch knowledge that was never meant for the sight of mortals. They’ll arm themselves with experimental technology and deadly weapons and learn to wield powerful magical spells or harness potent psychic powers to fight against this uncanny threat.

They’ll also encounter exotic native races like the Deep Ones, undersea worshippers of the dreaming god Cthulhu, or the strange Mi-Go, fungoid-insectoid beings from the furthest corners of the solar system who have come to Earth for an unknown purpose. Towering over them all are the monsters, entities, and gods of the Mythos themselves, who seek to take advantage of the chaos of the second world war to extend their dominion over the minds of men.

Will your heroes prevail against all odds, or will they, like so many others before, fall to the malign influence of the Mythos? That is your story to tell…

This is actually a fantastic dog toy!
Color: Large size (ø 7.4")
I originally got this for my golden retriever. He loves all things ball-shaped and I figured the handles would make this really easy for him to carry and for me to tug. It was a fantastic hit not only with the retriever but my lab and even my older Great Dane also love this toy. It's about the size of a soccer ball and covered in a nice rubber that can be chewed off if you have a destructive player but is more than durable enough for tossing around the house or even in the yard. Chewability-wise, The Dane managed to chew a couple of chunks off the handle part but he's probably a pretty extreme example. I think this would hold up just fine for most dogs' play. I just have to supervise it with my Dane so that he doesn't chew it into a pile of rubber. The biggest surprise of this ball was the fact that it has one of those slide whistles in it that makes a noise as it tumbles and rolls around. This proved irresistible to the Golden Retriever and the Lab. Every time they hear the slide whistle inside, they get up from wherever they are and focus 100% on this ball. It has some heft to it and it bounces a little but not as much as a regular ball its size, it's fun for the little ones to play with inside but it's primarily an outdoor dog toy. The handles are big enough for a human hand to hold them comfortably. It rolls in a hard-to-predict way that is extra helpful for the smaller dogs to chase.

Aggressive chewers have met their match.
Size: 10.5 inch Rubber Flex Tread
We purchased this toy in 2022, it finally broke last night. Four years of rough play with 2 boxers who are aggressive chewers. They would tug together, gnaw on it for hours, and often leave it outside exposed to the elements, but this toy just kept going. It was by far their favorite toy, it kept them busy for hours. I just ordered a replacement. Well worth the money, perfect size. Highly recommend.

Durable, fun, and safe for my dog
Size: 10.5 inch Rubber Flex Tread
I have a 10 month old, 50 lb mutt who has the musculature of a pit bull and the muzzle of a GSD. Buttercup’s favorite past-time is shredding toys into teeny tiny bits, but sometimes those bits don’t come back out of her mouth. She can’t have tennis balls, stuffies, anything with a squeaker, silicone toys, plastic toys, rubber toys with spikes or small appendages, anything with rope, or most chews & bones. She chewed her first and only $8+ XL bully stick like a corn chip. Finding indoor enrichment is a challenge. Buttercup is extremely pleased with this tire tug thingy, it is very ergonomic for both her and me to get a handle on it, it has more movement than any other toy she can safely have, and it’s very durable. After more than a week, there’s only a little bit of tread missing, which is definitely the best-case outcome with a super chewer. I think this is a good alternative to GoNut toys because it’s solid & dense while also a little bit easier & more interesting to play with, and very unlike GoNuts, this Tonka toy is very reasonably priced. I also think this it’s a good size for almost any breed of dog—I could definitely picture a little Boston or Frenchie dangling from one end. Highly recommended!

Dog loves it
Size: 10.5 inch Rubber Flex Tread
I would buy this again and again. It’s extremely durable and has held up great with my 9 month old Saint Bernard puppy. We even call it his “pacifier” because every night he grabs it and chews on it until he falls asleep. Definitely a favorite in our house!
