From the release:
They came from a clear sky, without warning. Black parachutes floating serenely from a sky devoid of aircraft.
It was the last serene day we’d ever experience.
We were invaded, from another dimension, by Nazis! Invaders from a universe where the Nazis didn’t lose WWII.
The Invasion of the Fourth Reich mini-setting / adventure provides the setup for a one-shot, short series or ongoing campaign in a world invaded by Nazis from another dimension.
The setting is the Core World (the Earth you live in) with dimensional portals allowing travel to and from Erde – the Earth ruled by the German Fourth Reich.
