Modiphius has announced the PDF release of Operation Vanguard, the first of our monthly Missions for Achtung! Cthulhu 2d20. A direct sequel to the Achtung! Cthulhu 2d20 Quickstart, this 29-page full-color PDF is available on as part of the Achtung! Cthulhu 2d20 Collection, and on

Discover the Secret of Skellen Island!

It is August 1940 and from the small Dutch fishing town of Nermegen, reports reach Britain’s Section M of a strange installation being constructed on the nearby Skellen Island. They also confirm the presence of Nachtwölfe, the Night Wolves, a Nazi occult organisation devoted to weird science and eldritch technology, who are said to rival Black Sun itself.

Seizing the opportunity, Section M dispatches a covert team by submarine to learn more about Nachtwölfe’s plans. Once in situ, the agents must contact the fledgling local resistance and gather detailed intelligence. Why are Nachtwölfe here? What happened at the forbidden site near the Arn river? What are these Night Wolves doing at St Olaf’s lighthouse?

The agents must piece together several component parts of this mystery, before finding a way to approach the heavily guarded Skellen Island itself. There, they’ll encounter advanced technology, strange, modified creatures, and face a deranged Nachtwölfe commander, intent on completing a bizarre bio-experiment, before confronting the horrifying truth which lies at the heart of Installation 41 itself.

Overshadowing all, is the malice of an ancient undersea race, who, provoked beyond measure by the unwise machinations of man are now ready to strike—a fearsome foe to contend with in Operation Vanguard, a brand new mission for the Achtung! Cthulhu 2d20 RPG!

  • Operation Vanguard is a sequel to A Quick Trip to France, the FREE Achtung! Cthulhu 2d20 Quickstart and follows directly on, for GM’s looking to run a linked narrative campaign.
  • Features a 29-page full colour PDF, with a daring mission for four to five audacious agents set deep behind enemy lines with full enemy profiles, NPCs, maps, and handouts.
  • Action, investigation and mayhem abound, as players first cross swords with Nachtwölfe and become embroiled with the Deep Ones, a major Mythos power.
  • Playable with the Achtung! Cthulhu 2d20 Quickstart rules, although the full Achtung! Cthulhu 2d20 core books are recommended.
