PC editions of hidden levels in Original-Xbox Ultimate Doom and Doom II
=======================================================================
The Old/Original-Xbox titles "Doom 3: Limited Collector's Edition" and "Doom 3:
Resurrection of Evil" include ports of PC Ultimate Doom and Doom II.  Each port
has all the levels from the original PC game, plus one extra level: "Sewers" in
Ultimate Doom, and "Betray" in Doom II.  These are hidden levels and were never
intended to be a part of normal gameplay.

Official PC versions of the hidden levels can be downloaded in a Zip file here:

WAD FILE INFORMATION
--------------------
The Xbox versions of Sewers and Betray have flaws that could prevent the player
from reaching the exit: In Sewers there is a tiny invisible pit just big enough
for the player to drop into and become trapped; In Betray a teleporter pad that
should work, does not.
SEWERSXB.WAD and BETRAYXB.WAD are the flawed levels in the Original-Xbox games;
SEWERS.WAD and BETRAY.WAD are the corrected editions, and supersede any earlier
PC WAD files for the same levels.

-------------------------------------------------------------------------------
Notes: A level in a WAD file temporarily replaces a standard level in the game.
The "Enemies" entry here shows the total enemies initially present when playing
at Skills 1 or 2, Skill 3, and Skills 4 or 5.  (Any Doom/Doom II level can have
three possible starting-enemy counts depending on the difficulty setting.)
"Secrets" are only those that affect a player's Secret score.
"Par time" is the correct time (Sewers and Betray Par times in-game are wrong).

DEMO FILE INFORMATION
---------------------
The demo files here can be played back using original DOS Doom/Doom II engines,
