Hearts of Iron: Oil-Free Era

God made a bad joke: In this reincarnation, the earth has no oil. In 1918, the First World War did not end, it just changed its form. The great powers fell into crazy "genital worship": building bigger boilers, casting thicker gun barrels, and pushing hundreds of tons of steam mechas onto the battlefield. They think this is the truth. Only Heinrich von Gudemann knew that this was just the zombies of the old days dancing. He is a major general in the empire and a calm watch repairman. He doesn't need a god, he just needs gears. In the basement of Zurich, he used alchemy to ignite the blue fire of alcohol; on the train retreating from the front, he recruited pianists who coughed up blood and future famous generals. Others are competing for tonnage, while he is weaving rules. When the ghost army on bicycles overturned the steam behemoth with wrenches and high-powered internal combustion engines, the old gods realized that not only gods could overlook the world, but also watch repairmen.
