This tome is intended as the essential reference work for mixing the Cthulhu Mythos with World War Two - primarily aimed at the GM/Keeper but providing a lot of detailed background for anyone wishing to explore adventuring in a 'weird war' style.
After a brief Introduction by Chris Birch, instigator of the concept, it's on to Chapter 1: From the Shadows. With a brief piece of atmospheric fiction, it launches into an explanation of what this game is designed to present: an alternate history of WW2 in which the Nazis are attempting, through their known interest in the occult, to recruit the forces of the Mythos to aid their quest for world domination. Whilst most of the material is generic, specific game mechanics are provided for both Call of Cthulhu and Savage Worlds, with tags to indicate them in the text as well as game-specific chapters to deal with topics like combat, strategy and Sanity loss. It then jumps into a timeline from 1907 through to April 1945, weaving fact with fiction. It's illustrated with period photographs and snippets of information on various individuals and events - all laid out to give the impression of a dossier - and is designed so that you can set your action whenever you choose. Of course, later events may be somewhat different depending on the outcome of your group's adventures.
Next, Chapter 2: Inside the Reich deals with the notion that this is an historical horror game and hence delivers some (mostly) historical detail. This type of game works best when you have a good grasp of the real-world history on which your alternate history is based and covers developments in Germany from 1920 on. It looks at the potentials for playing German characters and issues the stark reminder that the Nazis were nasty enough without help from the Mythos. Not everyone will be comfortable playing a German character - although again it must be remembered that not all Germans were as evil as Hitler... war is not football, you do not get to choose which side you support. Notes here make a good job of picking their way through propaganda to give a clear picture of what the average German, especially the average German soldier, was really like. It is an interesting argument which boils down to the concept that the Nazis were not evil due to Mythos influences even in this game, they were evil enough to seek out and attempt to weaponise the Mythos.
Chapter 3: Might Makes Right? moves on from general discussion of German history to talk about the military. Everything is covered from organisation to uniforms to everyday life in the ranks, giving a good impression of the German war machine of the time. There's quite extensive discussion of prisoner-of-war camps which may come in useful should Allied player-characters fall into enemy hands! This chapter ends with a wide selection of sample stat blocks for both German and Allied military personnel. Many real-world units are included, complete with historical notes.
Chapter 4: The Other Secret War then looks at the Great Game, the role of intelligence agencies, spies, signal interception and the like that went on behind the scenes. Here the history and operations of the real-world British, French, American and German intelligence services are covered in quite some detail. The 'Secret War' that is the main thrust of Achtung! Cthulhu is handled in the following chapter, Chapter 5: Secret and Occult Societies. This details many such societies in different countries around the world, mixing known occultists with invented ones quite seamlessly. Organisations and individuals (all with dual stat blocks) provide a ready source of contacts and ideas for adventures, as do the more detailed accounts of some of the ongoing operations, particularly those conducted by the Germans.
Next comes Chapter 6: Planes, Trains and Things That Go Bang. It is much more than an equipment list, with notes on travel by air, sea and land - including border crossings other than the conventional stroll up and present your passport - as well as details of military vehicles and vessels (in enough detail to keep the average wargamer happy) and equipment. The equipment covered here is German, British and Allied equipment is covered in the Investigator's Guide. More esoteric devices invented by German occultists are also included here. Every item is, of course, provided with both Call of Cthulhu and Savage Worlds statistics.
Chapter 7: Into The Fray opens with the immortal words "In case you hadn't noticed, there's a war on" and proceeds to discuss the perils of attempting to run a conventional role-playing style adventure in a combat zone as well as translating common battlefield events into convenient role-playing terms so that if your characters get involved, for example, in an aerial dogfight, you now have the rules to make it all happen within the context of the game. Chapter 8: Rules of Savage Engagement provide additional Savage Worlds game mechanics for use in military combat situations. This being a Mythos game, there is also a table for Sanity loss for those who find themselves caught up in the horrors of war.
This is followed by Chapter 9: Artefacts and Tomes which looks at some of the potent items and books that are around, particularly in Germany, to threaten or entertain the inquisitive seeker of occult knowledge. Several are based on real items held to be of almost-mystical significance by the real-world Nazis, now neatly embuded with power for game purposes - the Blutfahne and the SS Totenkopfring for example. There's a good library of dark and dangerous tomes too, some will be familiar to Call of Cthulhu veterans, but here they are provided with Savage Worlds stats (get the CoC ones from the core rulebook). Now you have all that occult knowledge, Chapter 10: Deadly Illusions and Cursed Knowledge shows you how to use it - in particular, how to cast spells and use artefacts to their full potential, as well as how to use the Knowledge (Mythos) skill to good effect as you try to puzzle things out, preferably before going insane or getting eaten. Budding spellcasters will find a goodly grimoire of spells here. Most are standard ones, so presented only with Savage Worlds mechanics, but there are some new ones with the mechanics for both game systems provided. If that's not enough, Chapter 11: Horrors and Monstrosities provides a vast array of monsters and worse with which to bedevil investigators. There's also a good overview of the Cthulhu Mythos for those new to it.
Next is Chapter 12: Allies and Nemeses, which introduces a wide range of notable individuals the characters might have an opportunity to meet and interact with during the course of the game. Many are real-world historical figures, others feature in Achtung! Cthulhu adventures or feature in this alternate history. Yet others are examples of ordinary people whom they might encounter. There is also a collection of choice generic locations that might come in handy. And now you have people and places, all you need is Chapter 13: Adventure Seeds to start coming up for ways to use them. Some nice ideas here, but you'll have to flesh them out to make full scenarios of them.
Chapter 14: Quick Play Guide is a useful ready-reference for Call of Cthulhu Keepers as to where they can find all the rules they'll need (Savage Worlds referees have all the Cthulhu-related rules they need in this book, of course, and the Savage Worlds rulebook for everything else). Finally, Chapter 15: Suggested Resources provides inspirational references to books and films - even a list of museums you might want to visit.
Presented in a style that suggests a sheaf of government paperwork, adorned with annotations and clipped-in phots and sketches, this book is a masterful exposition of how to weave an alternate history around the Second World War, and should put even the newest Keeper/Referee in a position to run an Achtung! Cthulhu game well.
