The Prince of Darkness Death Match was when they had the black hoods over their heads so they could not see each other, and that match took place during the 3rd Annual Jim Crockett Sr. Memorial Tag Team Tournament (April 22, 1988 in Greenville, SC).
 
The Tower of Doom Match was the 3 cages stacked on top of one another.  You start at the top and work your way down through the cage.  That match took place in Baltimore, MD at The Great American Bash '88 PPV.
