It is December 1944, and the Allies on the Western Front are turning back what appears to be one final Nazi counter-attack. Allied High Command has received word from the codebreakers at Bletchley Park that the much-rumored Nazi research into vril energy may be all too real and could threaten to turn the tide of the war.
Lurking in the depths of Wewelsburg Castle lie the bizarre results of the mysterious Project Vril: deadly machines, monstrous experimentations, and even creatures not of this Earth. With the castle too far from either front for a direct attack and time running out, a crack team, the Reichbusters, is assembled to infiltrate Wewelsburg on a mission to save the world.
