Welcome to the Secret War, a fast-paced RPG influenced by pop culture, which combines the horror of Lovecraftian cosmic terror with the chaos and heroism of World War II.

Explore a world of daring Allied agents, malevolent Nazi villains, and the incomprehensible gods and monsters of the Mythos, all striving to prevail in humanity’s darkest yet brightest hour!

Answer the call alongside the fearless men and women of the Allied occult forces: Britain’s Section M, America’s Majestic, or the brave Resistance, all willing to make the ultimate sacrifice to keep the legions of Nazi occultism at bay.

Battle the Black Sun, elite Nazi warrior-sorcerers who wield dark magic and summonings from nameless dimensions to dominate the battlefields. Fight against the Nachtwölfe, the Night Wolves, who harness technology, biological enhancements, and wunderwaffen (wonder weapons) to win the war for Germany. Can you prevail against such overwhelming odds, or will you succumb, like so many others, to the terror of Nazi occultism or the malevolent influence of the Mythos?

This is your story to tell!
