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.
