Dieselpunk
Dieselpunk is a retro-futuristic style developed from the industrial and wartime technologies of the 1920s to 1950s. It features heavy machinery, riveted armor, propeller aircraft, diesel engines, and militaristic industrial aesthetics. Commonly used in alternate history, war-themed science fiction, and retro-future settings, it conveys a rugged, hard-edged atmosphere filled with historical tension.
