OSR Campaign Slab - Amazing Adventures Rpg - Weird War II Campaign

One of the OSR campaigns that I've been tossing around is a Weird War II Amazing Adventures campaign setting. 

Amazing Adventures is having  Codex Monstorum Kickstarter style campaign & to get ahead of the curve I decided to kick up a Weird War II campaign. Here's what I've got so far in my notes and such. 

 Troll Lord Games’ Amazing Adventures (built on the SIEGE Engine) is ideal for a Weird War II campaign, blending gritty 1940s military action with occult horror, superscience, and dieselpunk elements.

Campaign Overview: Operation: Götterdämmerung

• Tone: Gritty survival horror meets high-pulp action (Wolfenstein meets Where Eagles Dare).

• Core Conflict: As the axis forces face conventional collapse, their clandestine occult wing—the Ahnenerbe—and their military science division—the Waffen-SS Wunderwaffe Directorate—unearth ancient horrors and alien technology to rewrite the war's outcome.

• Player Character Roles: An elite joint-allied unit (OSS agents, British SOE operatives, resistance fighters, defector scientists, and occult investigators) tasked with sabotage, asset retrieval, and neutralizing paranormal threats.

Key Campaign Mechanics (SIEGE Engine Adjustments)

• Sanity / Stress System: Exposure to eldritch horrors or resurrected legions requires a Wisdom Check (Challenge Base 12/18). Failure incurs temporary insanity, phobias, or cumulative Willpower penalties.

• Guns & Steel: Firearms follow standard Amazing Adventures modern weapon rules, but Wunderwaffe weapons (Vril-blast rifles, tesla cannons) add dynamic energy damage types and hazard risks on critical fails.

Timeline of Events (1939–1946)

Year	Event Name	Campaign Lore & Mission Hooks
1939	The Thule Excavations	The Ahnenerbe begins massive archaeological digs in Antarctica, Tibet, and Norway, recovering hyperborean artifacts, precursor metals, and black-earth rituals.
1940	The Black Sun Rises	Heinrich Himmler consecrates Wewelsburg Castle as an occult nexus. Axis occultists summon the first batch of bound entities to serve as night-guards and infiltrators.
1941	Operation: Necromancer	During the invasion of the USSR, specialized SS units use dark rituals to reanimate fallen soldiers on the Eastern Front, creating the first Nacht-Grenadiers (undead shock troops).
1942	The Vril Breakthrough	Nazi scientists successfully harness Vril energy from precursor artifacts, powering jet prototypes, early walker-tanks (Panzer-Mechs), and directed-energy weaponry.
1943	The Oslo Incident	Campaign Mission 1: Allied intelligence learns of a heavy-water facility in Norway that isn't making atomic weapons, but opening a rift to a dark dimension. PCs infiltrate to sabotage the gate.
1944	D-Day & The Blood Moon	Normandy landing forces encounter not just pillboxes, but chemical-beast hybrids and mechanized exosuits. Allies establish the Special Occult Taskforce (SOT-8).
1945	The Berlin Eclipse	As Soviet and Allied forces close in on Berlin, Hitler retreats to an underground bunker complex housing an ancient subterranean temple. The Nazi leadership attempts a ritual to pull Berlin out of linear time.
1946	The Weird War (Alternate Continuity)	Berlin is encased in an impenetrable black barrier. The war drags on as Allied forces battle mutant-plagued battlefields, V2 rockets bearing occult payloads, and rogue warlords wielding alien technology.

Major Factions

• The Special Occult Taskforce (SOT-8): The PCs' sponsor organization, combining OSS field agents, British decipherers, and esoteric scholars.

• The SS-Ahnenerbe & Order of the Black Sun: The primary antagonists, led by high-ranking occultists seeking divine ascension and demonic bargains.

• The Iron Legion (Eisen-Legion): Mechanized infantry units utilizing Vril-powered armor and cybernetic augmentations.

• The Underground Resistance: European partisans who have adapted to fighting both conventional occupiers and unnatural monstrosities.

The Forgotten Science Fictions Author & the Forgotten Earth -John Brunner As Hostile Rpg & Earth Sector Rpg Inspiration

 There are three Science Fiction  books that carved up the Nineties for a young college student that were found in a nameless box at a .25 cent book sale. These are John Brunner's Apocalpyse classic trio. These lovelies were decades ahead. Everyone claims William Gibson is the father of Cyberpunk but John Brunner was there already way ahead of the curve. John Brunner wiki entrygoes into the basics;  ;"John Kilian Houston Brunner (24 September 1934 – 25 August 1995) was a British author of science fiction novels and stories. His 1968 novel Stand on Zanzibar, about an overpopulated world, won the 1969 Hugo Award for best science fiction novel, and the BSFA award the same year. The Jagged Orbit won the BSFA award in 1970." Let me first say that this is not our Earth in anyway but the Earth's past of our Shoulder of Orion campaign. 

According to John Brunner's Wiki entry; "His 1968 novel Stand on Zanzibar exploits the fragmented organizational style that American writer John Dos Passos created for his USA trilogy, but updates it in terms of the theory of media popularised by Canadian academic Marshall McLuhan, a major cultural figure of the period.

The Jagged Orbit (1969) is set in a United States dominated by weapons proliferation and interracial violence. Its 100 numbered chapters vary in length from a single syllable to several pages. The Sheep Look Up (1972) depicts ecological catastrophe in America.

Brunner is credited with coining the term "worm" (in computing) and predicting the emergence of computer viruses^[4] in his 1975 novel The Shockwave Rider, in which he used the term to describe software which reproduces itself across a computer network. Brunner's work has also been credited for prefiguring modern developments such as genetic engineering, same-sex marriage, online encyclopedias, the legalization of cannabis, and the development of Viagra.^[5]

These four novels Stand on Zanzibar (1968), The Jagged Orbit (1969), The Sheep Look Up (1972) and The Shockwave Rider (1975), have been called the "Club of Rome Quartet", named after the Club of Rome, whose 1972 report The Limits to Growth warned of the dire effects of overpopulation"  If your thinking that this sounds like the 00's John Brunner was a   decade ahead of his time; "

"Cyberpunk, population stresses, environmental disaster...

Also had antibiotic resistant germs, mass-shooters being a multi-daily occurance so only the ones with exceptional body count or cruelty stand out, China replacing Russia as the threat to the USA, rise of racism after a period of decline, overpopulation and rent/housing stress but also with empty areas..." 

But what does a Science Fiction author whose passed into the great beyond have anything to do with 2d6 action of Hostile & Independence Games Earth sector?! A bit of everything really, this is an Earth bursting at the seams just before the discovery of FTL & hyperspace that changes everything. 
The world of John Brunner would be perfect for Independence Games Diverse Roles where the careers of your PC's help to fuel the future. 

John Brunner's Earth is a world in the later 00's struggling to find it's place in the universe. And super soldier programs are just starting to see fruit here. And the seeds of the altered humans movement is taking hold and here's where Tree of Life: Altrants in Clement Sector comes into play. We also see the results of early uplift experiments in the Shock Wave Rider which is perfect for Wondrous Menagerie to come into play. 
The retro technology of Hostile is at play in all three of the Apocalpyse triology. And perhaps more so with two story tall A.I. and the like. The baby steps of the synthetic's movement are being made. But clone soldiers are certainly available. 

How could the works of John Brunner be used for 2d6 OSR gaming goodness?! Easily the works of JB could be used as an alternative Earth for a time travel adventure or even a mini campaign. And the issues he confronts could become ancient history for the PC's as they struggle to get back to their own Earth timeline. Another possibility is to actually travel back in time to avoid the ecological disasters that befall the poor SOB's in 'The Sheep Look Up' if it's even possible.
