What you have here is a very special edition of DOOM. It contains a new, never-seen-before FOURTH EPISODE that makes the first three episodes look like a walk in the park! You also get 5 free hours of playtime on DWANGO, the DOOM Wide-Area Network Game Organization, where you can call up 24-hours a day and find someone to frag.

Just run the DWANGO program and choose the server closest to you, tell the server you’re a new user, enter your information, then log onto the server. Press the F5 key and choose Enter Authorization Number – type in the number that came with your ULTIMATE DOOM box.

id Software respectfully requests that you do not modify the levels for the shareware version of DOOM. We feel that the distribution of new levels that work with the shareware version of DOOM will lessen a potential user’s incentive to purchase the registered version.

If you would like to work with modified levels of DOOM, we encourage you to purchase the registered version of the game.

Make sure you read the DOOM FAQ v6.666 if you have any problems or are anxious to find out about the World of DOOM! The 4 files
of the FAQ are DMFAQ66A.TXT, DMFAQ66B.TXT, etc. Enjoy!

Welcome to DOOM. Before playing, you’ll need to read the DOOM manual and this addendum which contains information for playing in Multiplayer mode, as well as technical support and troubleshooting instructions. To avoid compatibility errors, please make sure that your machine and network conform to the system requirements listed below.

DOOM(TM) requires an IBM compatible 386 or better with 4 megs of RAM, a VGA graphics card, and a hard disk drive. A 486 or better, a Sound Blaster Pro(TM) or 100% compatible sound card is recommended. A network that uses the IPX protocol is required for network gameplay.

1. Install DOOM as described in the manual.

2. Launch DOOM from the SETUP program, by going to the directory in which you installed DOOM, type SETUP, and press the ENTER key. (If you are installing DOOM for the first time the SETUP program will be automatically launched.)

Unlike playing DOOM in single player mode, DOOM in multiplayer mode must be run either from the SETUP program or by using the command line parameters mentioned later in this addendum.

3. The SETUP program not only allows you to configure DOOM to your system but lets you tell DOOM information that is necessary for the multiplayer game, (i.e. number of players, kill level, mode, etc.) The SETUP program is simple to use–providing context sensitive help at the bottom of the screen.

NUMBER OF PLAYERS: A maximum of four people can play multiplayer DOOM on a network.

COMPATIBLE NETWORKS: To play multiplayer, you must have a network that uses the IPX protocol. Check your network manuals for information regarding your protocol. Novell networks use the IPX protocol.

MULTIPLE GAMES ON THE NET: To play a multiplayer game while another group is also playing the multiplayer game, you’ll need to change your network port address from the SETUP application. The port address tells your server where to send information that is sent over the network. Network addresses range from 1-64000. You should refer to the person in charge of your network for possible port addresses.

Many of the rules for playing DOOM change for the multiplayer game. Read the following information carefully before you begin to play DOOM in multiplayer mode.

MENUS: When you activate the Options menu or submenus, the game KEEPS RUNNING so that other players can continue with the action. So it is best to find a safe place before adjusting screen sizes or sounds.

UNPAUSE: A player may Pause the game by pressing the PAUSE key, but any other player can Unpause the game by pressing the PAUSE key again. Make sure it’s OK with your buddies before taking a breather.

SAVE: When you do a savegame during a network game, it saves on every player’s system in the savegame slot you select, writing over whatever was there. Before saving the game, players should agree on a safe slot to save in.

LOAD: You cannot load a saved game while playing a multiplayer game. To load a game everyone must quit from the current game and restart the game from the saved game. To start a game from a saved game, you can either select it from the SETUP program or identify it as a command line

WEAPONS: When a player runs over a weapon, he picks it up, but the weapon remains in the game for other players to take. Note: Shotguns dropped by former human sergeants are removed from the game after being picked up or smashed.

DEATH: If you die and restart in the level, previously taken items and destroyed monsters DON’T reappear. Even though you’ve died, other players have survived. We didn’t want to undo all of their fine destruction by reviving every monster in the area. However, this also means the level will eventually run dry of monsters and ammunition. You’ll have to decide when the level is played out.

UNIFORM COLORS: In net games, each player’s uniform is a different color. The color of your character is the color behind your face on the status bar. The colors are BROWN, INDIGO (black), GREEN, and RED.

CHAT MODE: In a multiplayer game you can communicate with other players in the Chat mode. To enter into Chant mode and broadcast a message to all the players, press the letter t. A cursor will appear where your messaging is normally placed. To broadcast to a specific player, instead of pressing t you’ll need to press the first letter of the player’s color. (B)rown, (I)ndigo, (G)reen, and (R)ed. For example, to send a message to the brown character, you would press the letter b.

CHAT MACROS: In a multiplayer game, you can send your own pre-defined macros (defined in the SETUP program) by initiating Chat mode (as stated above), then holding ALT and pressing the number key that corresponds to the macro you wish to send. For example, if macro #2 is “Eat it and die!”, initiate Chat mode by pressing ‘T’, then hold down ALT and press 2.

EXITING A LEVEL: When one player exits a level, all players instantly exit with him, regardless of their position or their status.

There are two ways to play multiplayer–DeathMatch and Cooperative. In Cooperative mode the players work together. In DeathMatch mode your mission is to kill everything that moves, including your buddies. You can choose which mode you wish to play from the SETUP application. The differences between Cooperative and DeathMatch mode are as follows:

WHERE YOU START: In Cooperative mode each player begins in the same area. In DeathMatch mode the players begin in completely different areas–if you want to see your buddy you’ll need to hunt him down. Plus, each time you die, you’ll restart in one of several random locations.

KEYS: Unlike in single-player or Cooperative mode gameplay, in DeathMatch mode the players start each location with the keys necessary for opening any locked door in that area.

STATUS BAR: In DeathMatch mode the ARMS section on the status bar is replaced with “FRAG.” The FRAG section displays the number of times you’ve killed your opponents.

AUTOMAP: In Cooperative mode the Automap works the same way it does in single-player mode. Each player is represented by a different color arrow. In DeathMatch mode you won’t receive the pleasure of seeing your opponents on the map. Just like the monsters, your friends could be just around
the corner, and you won’t know until you face them.

SPY MODE: If you’re playing in Cooperative mode, press F12 to toggle through the other players’ viewpoint(s). Press any other key to return to your view. You still retain your own status bar at the bottom, and if your view reddens from pain it is YOU, not your partner, who has been hit.

INTERMISSION SCREENS: In both Cooperative and DeathMatch mode the intermission screen tallies your achievement. In Cooperative mode the intermission screen lists the achievements for all players in the game. In DeathMatch mode the intermission provides a death count on everyone, letting
you know who killed whom.

The rules for completing or winning a DeathMatch game have intentionally been left general. Any player can exit an area and force all of the players to move to the next area. Also, there is no limit on how many kills are required to declare a player the winner. We decided to leave this up to you. You
know what you like best!

Note: Before you play DOOM in DeathMatch mode you should be familiar with the layout of every area in DOOM. As you know,in DeathMatch mode your startup location is random and often in an area that is very hostile.

You can record your tournaments for posterity! To record multi-player demos, add the line “-record demoz” to the command-line. Make sure the other player is recording also, or it won’t work. If you need more time, add the “-maxdemo <K>” option to increase demo buffer space. Make sure both of you specify the same amount. DOOM defaults to 128K of demo buffer space, to specify 1meg you would type “-maxdemo 1024” on the command-line.


When you wish to stop recording, press the Q or F10 keys and both players will exit to DOS. To play the demo back, merely type, “DOOM -playdemo demoz” and the demo will play back. To see the other player, press the F12 key. Press F12 to toggle between all players in the demo. The TAB key will display the automap.

You can set the name of the demo file to anything you want. “demoz” was just an example name.

Much of the information you give to DOOM through the SETUP program can be provided by passing program parameters to the appropriate device driver on the command line.

When you want to run a network game, you use IPXSETUP.EXE which is the device driver for DOOM’s network mode. The parameters are as follows:

-NODES starts DOOM as a network game and sets the number of players who are going to play. If you don’t specify the number of nodes, the default is 2.

-nodes <# of players>

-PORT sets the port from which to play DOOM multiplayer on the network. By setting a different port, more than one group of players can play DOOM on a single network.

-port <# of the port>

When you want to play a modem or null-modem game, you need to run SERSETUP.EXE which is the device driver for DOOM’s serial communications mode. The parameters are as follows:

-DIAL tells the program which number to dial, if you’re going to do the calling.
-dial <phone number>

-ANSWER puts your modem into Answer mode so someone can call you and play DOOM.

-COM1, -COM2, -COM3, -COM4 specifies which COM port your modem or serial cable is connected to. Very important!

-8250 tells SERSETUP to set the UART to 8250. Just in case your 16550 UART is acting up at the higher speed.

-IRQ sets the IRQ for the COM port.
-irq <irq number>

-PORT sets the COM I/O port that SERSETUP uses to communicate with your modem. To use hexadecimal, such as the number 0x3f8, you
would type “-port 0x3f8″. -port <port number>

-<#> sets the baud rate of your COM port, overriding the value in the MODEM.CFG if you’re running a modem game. Legal values are
9600, 14400, 38400, 57600.
Example: -14400

Note that to run a null-modem game, you must have a null-modem cable plugged into a serial port on both computers and each computer runs SERSETUP.EXE with a -COM# parameter as well as any General Parameters. Do not use the -ANSWER or -DIAL parameters, or SERSETUP will think you’re using a modem. To get a null-modem cable, go to CompUSA or Radio Shack and say,”I need a null-modem cable to run a DOOM multiplayer game.”

You will need to run the SETUP program and select Choose Modem from the Network/Modem/Serial menu so you can set your modem init string correctly. Merely select the modem and press Enter and SETUP will create a new MODEM.CFG file that corresponds to your modem (the MODEM.CFG file is used by SERSETUP for initing the modem.)

If your modem is not in the list, you will most likely need to edit the MODEM.CFG file in the DOOM directory. The first line of the file is an initialization string that:
* Turns off error-correction
* Turns off data-compression
The MODEM.CFG file has a Hayes-standard init string like this: AT Z S=46 &Q0 &D0 You just add your own commands after the “AT Z ” if your modem doesn’t work with these settings — dig up your modem manual for the correct settings.

The second line is a hangup string used when you quit DOOM.

The third line is the baud rate at which you want your COM port set. The legal settings are: 9600, 14400, 38400, 57600.

If the modem connection isn’t working when you call your friend, have him call you instead. Try setting the modem to GENERIC (in the SETUP.EXE program) if your modems don’t connect.

If you STILL can’t get the modems to connect, both of you should run your favorite COMM programs and connect with 9600, no error correction and no data compression. Then quit the COMM program and keep the connection going. Then just run SERSETUP with a -COM# parameter (as if you were running a null-modem game) since you’re already connected.

If you had trouble connecting, but figured out some settings that work, please fax them to us at (214) 686-9288 so we can expand our modem init string database and perhaps have the SETUP program ask you for your modem type in a future version of DOOM.

These parameters can be passed straight to DOOM, or passed to IPXSETUP or SERSETUP, which then pass them to DOOM.

-LOADGAME allows you to start DOOM from a specified save game. Instead of using the saved game name, simply enter the number that corresponds to the slot you saved the game to on the SAVE GAME screen (0-5). -loadgame <# of the game>

-DEATHMATCH starts DOOM as a DeathMatch game. If you don’t enter DEATHMATCH as a command line parameter, DOOM will default to the Cooperative mode.


-ALTDEATH specifies respawning items during DEATHMATCH. NOTE: Invulnerability and Invisibility do not respawn.
-deathmatch -altdeath

-SKILL sets the skill level (1-5) you wish to play. Only useful with -warp — see below.
-skill <# of skill level>

-EPISODE sets the episode (1-3) you wish to play. The default episode is Episode One, Knee-Deep in the Dead.
-episode <# of the episode>

-CONFIG allows you to use your configuration file from any directory you choose. This is primarily for diskless workstations that don’t have a C: drive to save config information to. You need to rename the default.cfg file created by the SETUP program to a directory and name of your choosing to avoid conflicts. -config <pathname> ex. -config f:\doom\data\myconfig.cfg

-NOMONSTERS allows you to start playing with NO MONSTERS running around! This is great for DeathMatch where, really, the monsters
just get in the way. Only useful with -warp — see below.

-RECORD tells DOOM to record the game you are starting. Demo files will be saved as <filename>.lmp.
-record <filename>

-MAXDEMO xxx If you want to record a demo bigger than 128k, use this option. xxx will be the size (in kilobytes) of the demo. example -MAXDEMO 1024 will record a 1 megabyte demo.
-record <filename> -maxdemo xxx

-RESPAWN tells DOOM that, yes, you are a badass, and yes, you want all the monsters to respawn around 8 seconds after you kill them. The NIGHTMARE skill level already does this. Note that using -respawn and -nomonsters at the same time is a dumb thing to do. Only useful with -warp — see below.

-TURBO xxx gives you a speed boost. This is great in DeathMatch! The value xxx can be from 0 to 250. The other player(s) will be notified of your speed increase! THIS IS CONSIDERED CHEATING IN SINGLE PLAYER MODE!
-turbo xxx

@<filename> will allow you to specify a Response file that DOOM will read additional command-line parameters from. For example, typing ‘DOOM @MYPARMS’ will tell DOOM to look in the MYPARMS file for additional command-line parameters. The file format is simply one parameter per line with a carriage return to terminate the line. Each parameter is typed exactly as you would type it on the DOS command-line.

-FAST will make the monsters move and shoot up to 3 times faster, just as if you were playing in Nightmare mode, but without the respawning. Only useful with -warp — see below.

-TIMER <# of minutes> will make DOOM exit the current level after a specified amount of minutes, going to the intermission screen.
This option is only useful in DeathMatch mode.
-timer xxx

An example line for entering the above information would be: doom -loadgame 3 -deathmatch -skill 4 -timer 10

IMPORTANT: Only the following command-line parameters are available while using the -WARP parameter:
-fast, -nomonsters, -skill, -respawn.

You must use a text editor (such as EDIT that comes with DOS) to edit the MODEM.NUM file. The format is simple. The first line is the Person’s name (which will appear in the list), the second line is the phone number. The third line should be blank.
