-This is a version of Freedoom MAP03 tweaked to fix some errors, including:
-
-1) One unclosed sector
-   Sector 68 consisted solely of two one-sided linedefs outside the valid
-   playing space to the sides of the doors to the blue key.  It has been
-   removed.
-2) Moving doortracks
-   These were on the following linedefs:
-    - 387, 728 (sides of the first door)
-    - 466, 472 (door into secret sector 85)
-    - 529, 530, 531, 532 (doors to the blue key, which were all /Upper/ Unpegged
-                          for some reason)
-    - 1054, 1057, 1060, 1063 (doors activated by linedef 1383
-    - 2021, 2026, 2054, 2055, 2056, 2057 (sides of the door immediately after
-                                          the blue key-locked door; the
-                                          DOORTRAKs were /Upper/ Unpegged)
-    - 2788, 2789 (sides of the door to a secret switch opened with the gunfire
-                  switch; textures changed from DOORSTOP to DOORTRAK)
-    - 2797, 2800 (sides of the door to secret sector 485; textures changed from
-                  DOORSTOP to DOORTRAK)
-3) Inaccessible secret
-   The gunfire switch was only accessible if you had a super shotgun, but the
-   only super shotgun in the whole map is in the secret accessible only with the
-   switch revealed by the gunfire switch.  The gunfire switch has been lowered,
-   so that you can now shoot it with any hitscan weapon.
-4) Lack of multiplayer
-   There were no deathmatch player starts on the map.  I added four of them,
-   shotguns and some shells provided for each position, and some doors in this
-   spots that could not be opened from their other ends now can.
-5) Unmarked locked doors
-   There are now better indicators of which keys are needed to open each door.
-6) Other odd stuff
-    - The door into secret sector 85 was unmarked.  It has now been marked by
-      shifting the alignment on its front side two map units down.
-    - The big crate near the gunfire switch (sector 234) had CRATE3 on the
-      sides, but the sector was raised to the point where the top of the brown
-      crate was clearly visible underneath it, sticking out of the floor.  It
-      has been altered to CRATELIT, with the texture alignment, flat, and floor
-      height changed accordingly.
-    - The yellow key-locked door was textured with BIGDOOR2 despite being only
-      64 units wide.  It has now been textured with SPCDOOR2 instead.
-    - In some places, you climb onto the monitors, which could mess up movement
-      around the yellow key.  This is no longer possible.
-
-Hope I didn't miss anything!
