Munich seems to be a map based on the Olympic Village in Munich, Germany. This map was recreated in the First Strike DLC by Stadium. Most of the buildings are the same but with different color schemes.
The map was apparently scrapped late in the game's development, as vote icons were created for it.
The map seems to be based on the Olympic Village in Munich and site of the hostage taking of 11 Israeli athletes by Palestinian terrorists at the 1972 Olympic games.
