Sitting in a top secret bunker one night puzzling over some challenging physics problems, some futuristic artifacts are amazingly teleported to the player—in the role of a US Army scientist—along with a note that says the artifacts are from the future, a future in which the Nazis won World War II and subsequently were able to enslave the entire world. The scientists who sent the artifacts did so in a hope that the player could reverse the outcome of the war, a war Nazi Germany should have rightfully lost.
