Achtung! Cthulhu

From website:

Welcome to the Secret War in this fast-paced pulp-influenced rollercoaster of an RPG which nimbly mixes the sanity-challenging terror of Lovecraftian cosmic horror, with the chaos and heroism of World War II. Enter a world of audacious Allied agents, malicious Nazi villains and the unfathomable gods and monsters of the Mythos themselves, each striving for supremacy in mankind’s darkest yet finest hour!

Answer the call with the dauntless men and women of the Allied occult forces: Britain’s Section M, the United States’ Majestic, or the brave Resistance, all willing to make the ultimate sacrifice to hold back the legions of the Nazi occult.

Battle the Black Sun, Nazi warrior-sorcerers supreme, who use foul magic and summoned creatures from nameless dimensions to dominate the battlefields of men. Struggle against Nachtwölfe, the Night Wolves, who utilise technology, biological enhancements, and wunderwaffen (wonder weapons) to win the war for Germany.

Can you prevail against such overwhelming odds, or will you succumb, like so many others, to the terror of the Nazi occult or the malign influence of the Mythos? This is your story to tell!

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 during 1939-1945.

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 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 artefacts 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…
