This patch employs a completely new approach to playing DOOM II! As in 
the
first version, you still have the "death scream" (which basically clears 
the entire
room at the touch of a button as you point your hand). New features include
inanimate
objects that float around the room until you pick them up. This was done
without
sacrificing the amount of enemies! Weapons include the arachnotron
launcher.
Requires DEHACKED.EXE v2.0 (available in Library 8 (Action Game Aids) as
DMHKUP.ZIP).
