DOOM GOLD FOUR BRIGHT from ENIGMA-13. This is
THE FIRST sound/lighting PWAD to be created
exclusively for use with commercial DOOM II
Hell On Earth!  This changes a few of the    
sounds in DOOM-II with BETTER sounds, and it
turns the light on too! No IDBEHOLD! :) Try
playing DOOM2 straight first.  Then add in
this PWAD and you'll see the difference! E-13
