E3M9: The Lost Chord (2002 A Doom Odyssey)

E3M9: The Lost Chord is the ninth and secret map in episode The Evil Unleashed of 2002 A Doom Odyssey. It was designed by Sam Woodman (Metabolist) and uses the music track "Party in Hell" by Paul Corfiatis. In the 10th anniversary edition no geometry changes were made (apart from an increase in vertexes due to node building) and the things distribution remained the same.
