Modiphius LOGO


Today we’re delighted to announce the release of a brand new mission for Achtung! Cthulhu 2d20 with Operation Falling Crystal by Brad Bell making its debut, an adventure where you first face the might of the malevolent Mi-Go!


Operation Falling Crystal is available in PDF only on  DriveThruRPG.com. There’s also a brand new blog over at Modiphius net,  from John Houlihan detailing what you can expect to discover in the Secret Weapons of the Secret War chapter of the Gamemaster’s Guide. An announcement on final release is described as “imminent” and you should check out the blog for further details! In the meantime, here’s the full briefing on Operation Falling Crystal.


Face the malevolent menace of the Mi-Go!


As summer bleeds into autumn in 1940, the Battle of Britain rages over England’s southern skies. As the RAF’s Spitfires and Hurricanes struggle to contain the might of the Luftwaffe’s daily raids, an unusual discovery at a remote Scottish site catches Section M’s eye.


A valuable cache of Blauer Kristall or Blue Crystal has been uncovered during an archaeological dig and this rare substance is known to be coveted by the Nazi occult organisation known as  Nachtwölfe. A team of agents is dispatched to secure this invaluable resource, so it can be studied and analysed by the boffins at Clemens Park.


But what awaits them in the sleepy village of St Abbs is a whole lot more than they bargained for with Black Sun agents, unnatural hazards, Mythos creatures and the machinations of a sanity-defying alien race all laying claim to their treasure. Can your agents prevail in the face of such monstrous odds and what will they make of their first encounter with the malevolent Mi-Go in this brand new mission for Achtung! Cthulhu 2d20?


  • Operation Falling Crystal is a 23-page PDF adventure for 4-6 agents, and comes with both full colour and printer friendly versions, plus three maps, and seeds and advice for continuing the story.

  • Features an intriguing mission which requires a mix of skills including exploration, combat and diplomacy.

  • This sequel to Operation Vanguard can be slotted into your existing early war campaign or played as a standalone adventure.

  • The perfect way to introduce the malevolent menace of the otherworldly Mi-Go into your storylines.

  • Fully playable with the FREE Achtung! Cthulhu 2d20 Quickstart rules, although the full Achtung! Cthulhu 2d20 core books are recommended.

We hope you enjoy this latest Achtung! Cthulhu 2d20 release and look out for more missions and final announcements on launch plans, coming soon!

Best wishes,

Modiphius Entertainment
