Super weapon
A Super weapon was a class of German weapon during World War II. 

After a major explosion in a  holodeck running a World War II simulation, rooms and corridors adjacent to the holodeck became visible to the holodeck characters, and American forces saw what appeared to them to be a mysterious and highly advanced Nazi facility. Upon conferring with Military Intelligence, it was concluded that they may have uncovered an advanced munitions laboratory designed to build some kind of super weapon. ()
