The story so far...
Our hero is Lt. Col. Charles "Chunk" Pylon, secret agent
for U.S. Army Intelligence. Dropped behind enemy lines to investigate an unusually high concentration of troops, Chunk has made a chilling discovery: in order to bring about their quest for world domination, the Nazis have brought together two of their most hideous creations.

Of course, these maps only show the general layout of each floor; they don't reveal the locations of troops, items, or secret rooms, and some details have been left out, or have changed in the years since the castle once again became a military installation. Chunk is smuggled in the back of a
