All Nightmare Long is the fifth track and fifth single on Death Magnetic. It appears to contain segments from an unused song from the St. Anger sessions entitled, "Shadows of the Cross." A "Single Collector Package" will be released on December 15. A music video of this song was made in which in the year 1913 the USSR finds a spore that is able to reincarnate the dead. They learn how to control it and in 1949 release the spore on America. The spore causes a zombie apocalypse in the United States. Within days the country and it's military forces are overrun. Russia then takes out the spore and claims America as its own.
