Description             : Presented as an immediate sequel to Doom ][, 
The Long Trek Back Home sees you through the old levels in reverse order;
Icon of Sin is the first and Entryway the last. Though the
respective areas are familiar, great upheavals have taken place:
destruction and Hellish subversion ensure that there is as much new as
there is old. From the caved-in ruins of Hell to the corrupted cityscape
to the former spaceport suffused in demonic magic, the road home is long...

This is the updated version 1.1, for details please read the included
text file LONGTUPD.txt.

LongTrek is a new 32 level megawad for DOOM ][. It is designed to be 100%
vanilla compatible and balanced for pistol start. As described, the new 
levels are themed after their predecessors from D2, with a major exception
being that you begin from the end and finish where it all started. This
applies to the individual levels as well: the former starting room is now
the goal and the exit is where you now begin. The style can be compared to
that of "Deimos Deja Vu", but the individual areas are now a bit more
accurate in terms of their relative positions with each other. Overall,
hard and fast rules are shunned and the goal is to provide new experiences
that pay tribute to the original levels in different ways.

Almost all music tracks from D2 are updated to fit each individual level's
mood, so even what were duplicate tracks in the original game now sound
different.

While there are some new graphics like the title screen and intermission
screen, there are NO new walls or flats aside from the 3 new skies in order
to retain the look & feel of DOOM ][.

There is a Dehacked patch file included, which changes the automap names,
story text and changes the flags of a few gib things so they don't float
in the air (thanks to Keyboard_Doomer for the tip).

The skill levels are overhauled. UV is still the same and considered the 
default skill level. HMP is otherwise the exact same, but has more ammo
items, while HNTR has extra health items. Because of the hard-coded
increase in Spawn Cube fire rate that HNTR and ITYTD have, relevant areas
are slightly more difficult in those skill levels. If the amount of
health or ammo is unpleasantly low, please give the new skill levels a try.
The level of difficulty expects that you are reasonably proficient in Doom,
having at least finished the original D2 first. Also, like mentioned, the
levels are balanced for pistol start.

Multiplayer support is included, with co-op and DM starts and multiplayer-
only items plus countermeasures against getting stuck because of level
gimmicks. However, multiplayer has not been tested extensively.

I recommend the wad be played with software rendering as
the visuals are built around the default palette and lighting levels.
The wad has been tested with the usual rules: no vertical mouselook, auto
aim on, infinitely tall monsters, limit on Pain Elemental souls.
As for music, "Arachno Soundfont" works very nicely, and for a more
lo-fi sound "hisymak_genmidi_2017-11-29.wad" works fine.

Bug Info & limitations:
-Some secrets may be given away if a source port's "textured automap"
feature is used.
-The "deep water" effect used in several places causes a Hall of Mirrors
if the viewpoint is lowered enough (by dying).
-In vanilla, some areas will experience Hall of Mirrors in the distance
because of a seg overflow, and the sprite limit can be hit in some areas
causing sprites to flicker in and out of view.
-Some areas that are inaccessible in normal play have confirmed visplane
overflows in vanilla: including at least the top of the blood falls in
MAP05: The Abandoned Mines and the lava sea in MAP19: The Factory.
-Several areas are subject to the "Ghost Monsters" engine bug. There are
often rockets placed at areas where these ethereal enemies may be born;
try using the splash damage to kill them if you encounter them.
-MAP07: The Chasm: The stair triggered by tag 667 is built to allow
passage even if the last 2 Arachnotrons die simultaneously, but three or
more will raise the stair too high and make it impossible to leave.
-MAP31: The special visual effect behind the windows is ruined if the 
player gets the invulnerability and runs back to the starting area.
-MAP16: The Inmost Dens: Not a bug, but for your information the red key
is absent on purpose despite the presence of a red-key locked door. In
multiplayer there is a BFG behind the door.
-MAP16: The Inmost Dens has a "Closes after 30 seconds" door (type 10),
which is subject to an engine bug: if the door is blocked from closing, 
it will rise indefinitely in vanilla and cause a crash after enough time
if the area is re-entered.
-MAP22: The Pit: the exit teleporter is opened by lowering layers of
walls around it by pressing eye switches. Since the mechanic uses the
"Lower to Lowest Floor" trigger, it is possible to 'waste' switches,
especially in multiplayer, by pressing them too early which causes the
next layer not to lower enough.
There are more switches than minimally necessary; if you get stuck, 
get all the keys and check the northern corridor of the BFG secret.
-MAP29: Underhalls: Multiplayer: if two players press the two 
floor-lowering secret switches (linedef 3551 and linedef 3562) close to
simultaneously, the associated secret can become inaccessible.
-MAP30: Entryway: Not considered a bug: there are purposely immobile
Specters in a certain area.
-No Monsters mode: note that several maps depend on switches that kill
Commander Keens to create combination locks for doors. Since Keens do not
spawn on -nomonsters, this will usually render the affected levels 
impossible to finish. However, when playing in Deathmatch mode, players
may spawn at DM-exclusive locations that cause the Keen doors to open
upon leaving. Note also that MAP07: The Chasm utilizes tags 666 and 667
with the Mancubus/Arachnotron death mechanism. 
The following maps are affected:
MAP07
MAP09
MAP11
MAP18
MAP19
(MAP21) (has an alternate route)
(MAP22) (has an alternate route)

-Vanilla: savegame limits confirmed to crash the game upon saving in
the following maps:
MAP08
MAP18
MAP20
MAP21
MAP30

Because the amount of things changes during play, other maps may also
be affected! Be cautious if you decide to save the game in vanilla.
-The default OPL emulator in Chocolate Doom may distort the music and
play it at a higher tempo, even locking up the game with certain tracks
like EVIL (MAP31 and ending.) Recommended to use another OPL or MIDI
playback solution if you encounter this problem.
-MAP20: Circle of Death may be affected by the bug where projectiles
trigger linedefs; the single-use teleports on the spiral steps are
used up early, therefore making the level shorter. This "trick" might
be used in other levels as well.

-Because of string space limitations in Dehacked, automap names don't
include level numbers. Refer here if you get lost:
MAP01: Icon of Sin
MAP02: The Living End
MAP03: The Spirit World
MAP04: Monster Condo
MAP05: The Abandoned Mines
MAP06: Bloodfalls
MAP07: The Chasm
MAP08: Barrels o' Fun
MAP09: The Catacombs
MAP10: Nirvana
MAP11: Gotcha!

MAP12: The Citadel
MAP13: The Courtyard
MAP14: Tenements
MAP15: Suburbs
MAP16: Industrial Zone
MAP17: The Inmost Dens
MAP18: Downtown
MAP19: The Factory
MAP20: Circle of Death

MAP21: Refueling Base
MAP22: The Pit
MAP23: Tricks & Traps
MAP24: Dead Simple
MAP25: The Crusher
MAP26: The Waste Tunnels
MAP27: The Focus
MAP28: The Gantlet
MAP29: Underhalls
MAP30: Entryway

Thanks to skepticist for informing me of the stuck bugs in MAP02 and
MAP13 in addition to the point of no return in MAP19, which were fixed in
this version.
