Towards the end of World War II the staff of SS officer Hans Kammler made a significant breakthrough in anti-gravity.
From a secret base built in the Antarctic, the first Nazi spaceships were launched in late ‘45 to found the military base Schwarze Sonne (Black Sun) on the dark side of the Moon. This base was to build a powerful invasion fleet and return to take over the Earth once the time was right.
Now it’s 2018, the Nazi invasion is on its way and the world is goose-stepping towards its doom.
What? There are fascists living on the moon? This looks like a job for G.I. Jerry. I need a M1 Garand and a spacesuit quicklike.
