In Assault on the Mountains of Madness, Achtung! Cthulhu players will follow in the snowy footsteps of the Pabodie expedition from HP Lovecraft's At the Mountains of Madness and take part in an epic, full-blooded campaign at the far flung ends of the earth.

There you'll discover the secret history of the final days of World War Two, when the Allies join forces with the Soviets to battle the Third Reich in the most dangerous theatre of war yet... the snowy plains, icy mountains, and subterranean tunnels of Antarctica.

Together, your brave soldiers must battle Nazis, occult conspiracies, monstrous foes and ancient horrors, as well as the very land itself. At stake is not only your own survival, but the very fate of the world itself!

Assault on the Mountains of Madness brings the Secret War to an earth-shattering conclusion, and includes:

A terrifying World War Two campaign, fully compatible with the Call of Cthulhu, Sixth Edition and Savage Worlds roleplaying games
A SEVEN-Part Adventure taking the investigators from the mid-Atlantic to the centre of Antarctica
Become part of a multinational military force transported aboard an experimental aircraft carrier
A branching plot structure allowing investigators to participate in all phases and fronts of the assault
The rise of a long-vanished civilisation and the unearthing of its greatest mystery
New skills and rules for exploration and cold-weather survival, new monsters, new horrors, and hideous twists!
Assault on the Mountains of Madness is a vast 248 page colour hardback campaign written by acclaimed author Jason Durrell and boasts a wealth of fantastic cover and interior art from some of Modiphius' finest illustrators like Dim Martin, Pierre Droal and Yap Kun Rong.

It's designed to be the climax to the entire Achtung! Cthulhu Secret War campaign and will send your investigators on an adventure to one of the most remote places on earth, where they'll face enemies from both this world and aeons past. Achtung! Cthulhu fans are advised not to miss this spectacular conclusion to the Secret War!

To him and the friend of his friend;
But never a man
shall friendship make
With one of his foeman's friends.
