All good things must come to an end. That includes even Achtung! Cthulhu's Secret Wars. It has all been leaning up to this. All the crazy madness and exploration has led you to one of the most iconic places in the Lovecraftian world. Now it's time to launch the Assault on the Mountains of Madness... since, y'know, the book's now available.
The book includes 7-part adventure that takes players from the mid-Atlantic all the way to Antarctica. The British and Americans have teamed up with the Soviets in a race against the Third Reich as they attempt to uncover and use the terrors of the Ancient Ones against the Allies. Things will be getting rather cold, so make use of new cold-weather survival skills and gear. Of course, there will be plenty of new horrible monsters to take out. Will you be able to beat out Hitler and save the world from more than just the iron heel of the Germans? Only if you can keep sane.
