RanDOOM is a utility which will
randomize the placement of objects
in the DOOM playfield. Additionally,
RanDOOM has some smarts about the
manner in which it will randomize
things - it's designed to never
leave you with a pillar blocking
the exit, or a keycard on the
opposite side of the door from where
you start, or to erase all the
DEATHMATCH warp-in spots with other
objects preventing DEATHMATCH
network play, or to replace the
endgame bosses with other objects
(thus preventing the completion of
an episode). In short, RanDOOM should
always leave you with a playable level.
