Is it this http://blog.starwreck.com/2009/11/04/iron-sky-operation-highjump-gets-its-game-on/ based on this movie http://www.ironsky.net/ ?
I looked up “Operation High Jump” in a search engine and it has Antarctica at http://en.wikipedia.org/wiki/Operation_Highjump . It reminded me of a conspiracy theory that I also heard that I don’t believe that Americans, British, or Nazis crashed a submarine with The Spear of Destiny into Antarctica. If you’ve played The Spear of Destiny, then the spear of destiny was used to stab Christ on the cross in folklore.
There’s Laz Rojas’ Operation Arctic Wolf: Special Edition for Doom 2. It has Wolfenstein 3D graphics.
Hollow Earth? I haven’t watched the Journey To The Center of The Earth movie in over 20 years, but you may like it.
