Wolfenstein: The Rising Sun

(A/N: Based on a map I found titled 'Japanese Wolfenstein' on DeviantArt. As the name implies, this is an alternate version of the Wolfenstein series where it is the Empire of Japan that rules the world instead of Nazi Germany. My main OC faction is the Union of American Continents which you can find in my story book titled 'My Military Factions (Heroes)' to learn more. My main OC character is John S. Grant who you can find in my book titled 'My Hero Characters' to see more.)

Summary: It is the year 1981 and the Japanese Empire rules the world with an iron fist. No one knows how it happened, but by 1946, the allies were being viciously pushed back by technology and weapons that were way ahead compared to what any nation could ever create. Not even Nazi Germany could even reach the technological level Japan was currently at. After failing to destroy the Unit 753 main HQ, both the American Pacific Fleet and the Royal Navy's Pacific Fleet were decimated and destroyed, allowing the Japanese to begin overrunning the Pacific. With no one to stop the Imperial war machine, nothing stopped Japan from conquering the entire world. Even Germany and Italy, Japan's 'allies' were betrayed and their nations annexed. B.J. Blazkowicz, 14 years after WW2, has awoken in Korea where the world is forced into submission by the Imperial Empire. Despite starting a new resistance movement and kickstarting a revolution in hopes of toppling the Imperial regime, the Japanese Empire remains strong, and more dangerous than ever before. But hope was not lost. After the Empire of Japan successfully opened a portal to another dimension, they launched a massive invasion force to conquer the other side, only for their military to be brutally pushed back. It was here that Imperial Japan had made the dumbest mistake of its life and that was angering a slumbering Titan who now wanted revenge. That enemy... being the Union of American Continents.
