World War Cthulhu


World War Cthulhu is currently unavailable while we retool to a brand new exciting system! It will return!

There’s a lot of old tales, if you know where to find them. Some old buffoons take them quite, quite seriously. Seriously enough to be very careful of talking about them, either from fear of ridicule or from... something worse. But I can trust you, of course. Mad idiot-savants across the ages have predicted the return of ancient evil, of incomprehensible god-beings. Asleep, for now, they say! But as the constellations move inexorably towards a dread alignment, they will begin to stir, and the mental shockwave of their awakening will end us all in some kind of lunatic baptismal self-destruction.

Say for a moment that there is a kernel of truth in these legends. Indulge me, please. I saw many things on the Western Front; the best of man, the worst of man. The question I ask myself about the nightmare situation I described is: will we even make it that far? What if the merest start of these end times is enough to push humanity over the edge? And are the horrors we have seen in this war-blighted century the beginning of our descent?” – Col. Arthur Pickering (Ret’d), Hastings, 17 March 1938

World War Cthulhu is a range of settings and scenarios for the Call of Cthulhu roleplaying game. The core settings will focus on conflicts in the 20th Century, as players struggle against two existential threats – the influence of the Cthulhu Mythos, and humanity’s own darkest aspects. The first core setting is World War 2, the second, Cold War. These are to be followed by the First World War and World War Three.

World War Cthulhu: Cold War

Cold War Packshot550

World War Cthulhu: Cold War is a Call of Cthulhu setting full of thrilling espionage, tense horror and sudden betrayal set at the height of the Cold War in the 1970s. The tangled webs of the spymasters tear and rejoin, double and triple agents make their moves and counter-moves, and it’s hard to be sure which side you’re really working for. Nuclear destruction hangs over everyone, and a few people at the heart of western intelligence continue their personal battle against the insidious influence of a much older enemy…

Western intelligence is possessed. Very few have heard of Section 46, and even fewer actually believe it exists, a loose cabal of agents drawn from across the western powers’ intelligence and military apparatus. Agents who have had a brush with something unworldly, alien and evil. Agents like you.

You work for the shadowy spymaster N against the insidious influence of the Mythos, but the enigmatic H also haunts the dreams of many agents. Active players in the Cold War, you need to maintain the confidence of your ‘home’ agency amid an atmosphere of distrust and suspicion. At any one time you might be engaged in multiple missions for multiple agencies, but not really clear as to where any of them have come from. Which mission objectives are valid and which must be kept deniable? Which are right, which are wrong? And can you really tell the difference?

You are forced to deal with forces the human mind cannot comprehend – the balance of power, the threat of nuclear war, and the ever-present danger posed by the Mythos. You don’t know who to trust any more – least of all yourself.

World War Cthulhu: Cold War is available in stores now, or from our webstore with free PDF, or in PDF alone.

The first supplement, Section 46 Operations Manual is also available.

World War Cthulhu: The Darkest Hour

The forces of fascism have overwhelmed Europe. Britain fights on desperately, and every man and woman must do what is necessary to avoid defeat. In forgotten corners, darkness stirs. The cycles of the ancient god-things are measured in millennia, but those who serve them plot to take advantage of the chaos of conflict to advance their own schemes.

For an unlucky few, the war collides with evils out of time, and they see and learn things that humanity is ill-prepared to encounter. The truly unlucky survive, and come to the attention of a certain spymaster, code letter N, who has plans for them. Pressed into the British Secret Intelligence Service, they are thrown into a desperate two-front war against the Axis forces and the insidious menace of the Cthulhu Mythos.

World War Cthulhu: The Darkest Hour is a World War 2 setting book for Call of Cthulhu from the multi-award-winning team of Dominic McDowall, Gareth Ryder-Hanrahan, Jason Durall, Stuart Boon, Martin Dougherty & Ken Spencer (writers) and Jon Hodgson, Paul Bourne, Scott Neil, Scott Purdy & Steffon Worthington (artists).
