ZDoom 2.7.1 (Requires a DOOM, DOOM 2, HERETIC, HEXEN, or STRIFE IWAD) ZDoom is an enhanced port of the official DOOM source code to Win32. As such, it not only works with (and requires) Windows 95/NT 4.0, but it also adds new features not found in the version published by id Software. ZDoom may be used and distributed free of charge. No profit may be made from the sale of it. ZDoom was created by Randy Heit using id Software's and various others' sources.
For those who want to know what I got for the mod so far, here are the files and directions you need to run and play it! (ZDoom instructions included, Doom II files NOT included).

WHILE ZDOOM HAS BEEN DISCONTINUED, ONE CAN STILL GET IT FROM THE DOWNLOAD FROM THE LINK SPECIFIED, AND IT WORKS ON GZDOOM TOO.

HOW TO RUN UNDOOM
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
-------------------------------------------------------------------------------------------------
For Mac and Linux Users
-------------------------------------------------------------------------------------------------
The following directions are designed for Windows systems.
Though there should be no issue ruunning this on other systems... this mod has not yet been
tested to run on other Operating Systems other than Windows.
ZDoom does offer sourceports for both Mac and Linux if you need it, though I will leave it
up to you all to find the directions for installation on your machines for the time being...
-------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------
1. Get a copy of zdoom-2.8.1
-------------------------------------------------------------------------------------------------
Go to the following website: Zdoom.org
Select your current Opertaing System
ZDoom will be dowloaded to your system automatically
Put your ZDoom folder wherever you wish to access your Doom mods from
-------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------
2. Unzip your copy of zdoom-2.8.1
-------------------------------------------------------------------------------------------------
RIGHT-CLICK "zdoom-2.8.1.zip"
LEFT-CLICK "Extract All..."
Specify your desired file directory (if unsure the default one will be fine)
LEFT-CLICK "Extract"
Now ZDoom is accessible on your machine!
-------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------
3. Get a Doom.WAD file for your ZDoom Sourceport
-------------------------------------------------------------------------------------------------
BUY a copy of Doom
A copy of Doom II (reccomended for best compatbility) can be purchased for $4.99 on Steam.
*If you purchase Doom II on Steam, ZDoom will auotmatically find it for you so you can skip
the remaining steps of this section...
In the files of your Doom II game copy, find a file with the extension ".WAD"
COPY this ".WAD" file
PASTE the ".WAD" file into your "zdoom-2.8.1" file
Now ZDoom has access to the full doom engine and can run doom mods--like undoom :)
-------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------
4. Ensure the following files are in "zdoom-2.8.1"
-------------------------------------------------------------------------------------------------
DECORATE.txt - cotains all mechanical changes
MAPINFO.txt - ensures player changes take effect
UNDOOM.pk3 - cotains all graphical and sound changes
-------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------
5. Run Doom with the UnDoom mod
-------------------------------------------------------------------------------------------------
LEFT-CLICK a blank area in the "zdoom-2.8.1" file window (to ensure your pointer has nothing selected)
while holding down the "Ctrl" button, LEFT-CLICK the following files:
DECORATE.txt
MAPINFO.txt
UNDOOM.pk3
With those three files simultaneously selected, DRAG-AND-DROP the files over "zdoom.exe"
If a box entitled "Select an IWAD to use" appears, LEFT-CLICK whatever doom game you would
like to run and LEFT-CLICK "Ok"
-------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------
NOTICE: To play mod with another map-pack...
-------------------------------------------------------------------------------------------------
same as step 3 but while holding down the "Ctrl" button, left click the following files:
DECORATE.txt
MAPINFO.txt
UNDOOM.pk3
the desired map-pack .wad file
-------------------------------------------------------------------------------------------------

HOW TO PLAY
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
-------------------------------------------------------------------------------------------------
Controls
-------------------------------------------------------------------------------------------------
Original Doom was built using tank controls, you are more than welcome to play like this, but
for those wanting to play with a modern FPS control scheme continue reading... you may need to
reconfigure your Doom controls to suit your comfort level.
UnDoom is built to play using the following controls:
Fire mouse1
Secondary Fire mouse2
Use/Open Space
Move Forward W
Move Backward S
Strafe Left A
Strafe Right D
Hold to Run Shift
Weapon Slots 0-9
1 Stunning Spear Fist OR Chainsaw
2 Pistol
3 Shotgun OR Super Shotgun
4 Chaingun
5 Rocket Launcher
6 Plasma Rifle
7 BFG 9000
Toggle Automap Tab
I would also recommend the following option:
Mouse Options >> Always Mouselook ON

General Doom Play Tips
-------------------------------------------------------------------------------------------------
The Super Shotgun and the Shotgun occupy the same weapon slot 3; press '3' to switch between
the two (same goes for the spear fists and chainsaw in slot 1).
Enemies will try to kill each other if one accidentially hits another (when trying to hit you)
Some buttons/doors can only be opened by attacking them.
Run over gaps to clear them (think Legend of Zelda Ocarina of Time?)
All Vanilla Doom maps are made to be completed without jumping or crouching
Most Custom Doom maps are made to be completed without jumping or crouching
Fall damage is does not exist in Doom
Floors with moving green or red textures usually equals hurt
Misaligned textures usually usually equals secret area
Hidden platform switches exist, be vigilant for changes in your surroundings!
Monsters can pop out of nowhere when collecting special items or using buttons
-------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------
UnDoom Play Tips
-------------------------------------------------------------------------------------------------
Use regular weapon attacks for an original doom experience
Use pistol and chaingun alt fires for powerful attacks
Use your spear to play maps pacifist style!
Enemies can un-stun each other by attacking each other
Enemies can be passed-through after being hit by the spear
Your spear alt fire can punch enemies with 3x the power of the vanilla Doom fist
The Beserk Pack only gives max health in UnDoom (Sorry! :P)
-------------------------------------------------------------------------------------------------
NOTE: The installation and running instructions are identical if you want to run this mod using GZDoom.
Description was a tad unclear... this mod replaces Doomguy with Undyne from Undertale, adds additional weapon functionality to the pistol and chaingun (see alt fires), and replaces the vanilla fists with less-lethal stunning spears (with 3x stronger punch alt fire) to make pacifist runs of Doom more viable.
