   ------------------------------------------------------------
   THE STORY SO FAR
   ------------------------------------------------------------
   You're a marine, one of Earth's toughest, hardened in
   combat and trained for action. Three years ago you assaulted
   a superior officer for ordering his soldiers to fire upon
   civilians. He and his body cast were shipped to Pearl



                                        page 1

   Harbor, while you were transferred to Mars, home of the
   Union Aerospace Corporation.

   The UAC is a multi-planetary conglomerate with radioactive
   waste facilities on Mars and its two moons, Phobos and
   Deimos. With no action for fifty million miles, your day
   consisted of suckin' dust and watchin' restricted flicks in
   the rec room.

   For the last four years the military, UAC's biggest
   supplier, has used the remote facilities on Phobos and
   Deimos to conduct various secret projects, including
   research on inter-dimensional space travel. So far they have
   been able to open gateways between Phobos and Deimos,
   throwing a few gadgets into one and watching them come out
   the other. Recently however, the Gateways have grown
   dangerously unstable. Military "volunteers" entering them
   have either disappeared or been stricken with a strange form
   of insanity--babbling vulgarities, bludgeoning anything that
   breathes, and finally suffering an untimely death of full-
   body explosion. Matching heads with torsos to send home to
   the folks became a full-time job. Latest military reports
   state that the research is suffering a small set-back, but
   everything is under control.

   A few hours ago, Mars received a garbled message from
   Phobos. "We require immediate military support. Something
   fraggin' evil is coming out of the Gateways! Computer
   systems have gone berserk!" The rest was incoherent. Soon
   afterwards, Deimos simply vanished from the sky. Since then,
   attempts to establish contact with either moon have been
   unsuccessful.

   You and your buddies, the only combat troop for fifty
   million miles were sent up pronto to Phobos. You were
   ordered to secure the perimeter of the base while the rest
   of the team went inside. For several hours, your radio
   picked up the sounds of combat: guns firing, men yelling
   orders, screams, bones cracking, then finally, silence.
   Seems your buddies are dead.

   It's Up To You
   Things aren't looking too good. You'll never navigate off
   the planet on your own. Plus, all the heavy weapons have
   been taken by the assault team leaving you with only a
   pistol. If only you could get your hands around a plasma
   rifle or even a shotgun you could take a few down on your
   way out. Whatever killed your buddies deserves a couple of
   pellets in the forehead. Securing your helmet, you exit the
   landing pod. Hopefully you can find more substantial
   firepower somewhere within the station.

   As you walk through the main entrance of the base, you hear
   animal-like growls echoing throughout the distant corridors.



                                        page 2

   They know you're here. There's no turning back now.

   ------------------------------------------------------------
   INSTALLING DOOM
   ------------------------------------------------------------
   DOOM is too large to run from a floppy disk, so before
   playing you must first install DOOM to your hard disk drive.
   To install DOOM, follow these steps:

   1. Make a backup copy of your original disks.

   2. Put disk #1 in your floppy disk drive and select the
   appropriate drive by typing A: or B:, then press the Enter
   key.

   3. Type INSTALL at the prompt and press the Enter key.

   4.Follow the prompts to create a directory for DOOM and to
   install it on your hard drive.

   5. After installation, DOOM will automatically run a Setup
   program. Follow the prompts to customize DOOM to your
   specific system. Please refer to your hardware manual for
   information regarding your system.

   6. To start DOOM, go to the directory in which you have
   installed DOOM (the default is DOOM), type DOOM, and press
   the Enter key. If you have finished installation and setup,
   you are automatically in this directory.

   -------------------------------------------------------------
   OBJECT OF THE GAME
   -------------------------------------------------------------
   Welcome to DOOM, a lightning-fast virtual reality adventure
   where you're the toughest space trooper ever to suck vacuum.
   Your mission is to shoot your way through a monster-infested
   holocaust. Living to tell the tale if possible.

   The gameplay for DOOM is quite simple. This is not a
   cumbersome adventure game, but an action-oriented slugathon.
   You don't need the reflexes of a hyperactive eight-year-old
   to win, either--using your wits is IMPORTANT. To escape DOOM,
   you need both brains and the killer instinct.

   -------------------------------------------------------------
   USING THE DOOM MENU
   -------------------------------------------------------------
   When you run DOOM a self-running demo will begin. To get to
   the menu press the Spacebar. Use the arrow keys, mouse, or
   joystick to move the skull cursor up and down. When the
   skull is adjacent to a desired selection, press the Enter
   key, left mouse button, or joystick Fire button to activate
   that selection.




                                        page 3

   If you're in a game, you can bring up the menu at any time
   by pressing the Escape key. Many of the Menu options can be
   activated directly by using a function key, thus bypassing
   the menus entirely. To exit the menu, press the Escape key
   or to return to the previous menu from a submenu press the
   Backspace key.

   NEW GAME
   If you want to jump into the action, select this. First,
   DOOM will ask you which episode to play. Then, DOOM will ask
   you to set the difficulty level. Each difficulty level
   differs in the toughness of the enemies you'll face.

   LOADING AND SAVING YOUR GAME (F2 and F3)
   Games can be saved or loaded at any time during the
   gameplay. To save a game, move the skull cursor to an empty
   slot (or one you don't mind writing over), and press the
   Enter key. This option is only available if you are
   currently in a game. To load a game, simply select the
   appropriate game from the Load Game menu.

   QUICKSAVE: Pressing the function key F6 allows you to Save a
   game without leaving the action. The first time QUICKSAVE is
   used in a given game, the standard Save menu appears. Select
   a slot. From then on, pressing F6 automatically saves the
   game to that slot without interrupting the fun of smackin'
   baddies around. Pressing F9 loads in the last QUICKSAVE game
   after prompting you.

   READ THIS! (F1)
   This, the most important part of DOOM, tells you how to
   order other copies of DOOM, and contains help for playing
   DOOM.

   QUIT GAME (F10)
   Quit Game enables you to quit from DOOM and return to DOS.

   END GAME (F7)
   This allows you to end the current game without exiting to
   DOS or loading a new game.

   MESSAGES (F8)
   In DOOM, whenever you pick up an item, you'll receive
   information about the thing you just picked up. This option
   lets you toggle DOOM's messages on and off.

   GRAPHIC DETAIL (F5)
   The default setting for the screen detail is HIGH. If you
   have a slower computer or video card, and the action is too
   jerky, you may wish to select LOW to make the game action
   smoother.

   SCREEN SIZE (+ and -)
   Just below this option is a bar with a sliding marker. When



                                        page 4

   this option is selected, you can use the arrow keys to slide
   the marker back and forth to adjust the viewing area. A
   smaller viewing area increases the smoothness of the
   animation on slower systems.

   SOUND VOLUME (F4)
   This selection has two bars with sliding markers, allowing
   adjustment of the volume from "off" to "maximum." One bar
   modifies the music while the other bar modifies the sound
   effects volume.

   MOUSE SENSITIVITY
   This selection lets you adjust the sensitivity of your mouse
   control. Just below this option is a bar with a sliding
   marker. When this option is selected, you can use the arrow
   keys to slide the marker back and forth to adjust the
   sensitivity of the mouse.

   TIP: Save your game and save it often. When you die, you're
   back to the beginning of the level, toting that little
   pistol again. That ain't good, especially after you progress
   to some of the tougher levels.

   -------------------------------------------------------------
   ON-SCREEN INFORMATION
   -------------------------------------------------------------
   DOOM provides on-screen information that's necessary to
   survive.

   THE STATUS BAR
   At the bottom of your screen is a gray bar (unless you've
   selected the largest possible screen size). From left to
   right, the segments of this bar indicate:

   1.MAIN AMMO: In big fat numbers, you see the number of shots
   you've got left in the weapon you're currently using.

   2.HEALTH: You start out at 100%, but you won't stay there
   long. At 0% it's time to start over. Try a little harder
   next time!

   3.ARMS: This list of numbers shows which weapons are
   available. If a number is highlighted, the weapon accessible
   by pressing that number is available. ("1" is always
   available.)

   4.YOUR MUG: This portrait isn't just for looks. When you're
   hit, your face looks in the direction from which the damage
   came, telling you which direction to return fire. Also, as
   you take damage you'll begin to look like raw hamburger--as
   shown to the left.

   5.ARMOR: Your armor helps you out as long as it lasts. Keep
   an eye on it, because when it goes, you might, too.



                                        page 5


   6.KEY CARDS: You can see any keys you possess right here.
   There are three key colors; Yellow, Red, and Blue.

   7.AMMO: This shows how much of each type of ammo you're
   carrying and the maximum amount you could carry--if you had
   it.

   MESSAGES
   Often you'll find yourself running over various bonus items
   and evil artifacts. DOOM tells you what you're picking up by
   printing a message on the game screen--unless you've turned
   the messages off.

   ------------------------------------------------------------
   THE AUTOMAP
   ------------------------------------------------------------
   To help you find your way around DOOM, you're equipped with
   an automap device. By pressing the Tab key, you replace your
   normal view with a top-down map of everything you've seen up
   to date. The white arrow represents you, and points in the
   direction you're looking.

   You can zoom in and out by pressing "+" or "-". Press the
   number "0" to toggle between zoom and full view. To mark
   your location on the map press the "M" key. This will place
   a number over your location. To clear all the numbers from
   the map, press the "C" key.

   Using the arrow keys, you can move yourself, while viewing
   the Automap. This is dangerous, since you can't see the
   enemy while viewing the Automap. To scroll the Automap
   without moving yourself, turn off Follow mode. Pressing the
   "F" key will toggle Follow mode on and off.

   -------------------------------------------------------------
   CONTROLLING THE ACTION
   -------------------------------------------------------------
   Most of the play commands in DOOM are a simple keypress
   away. You can use either your keyboard, mouse, joystick, and
   combinations of both to move, pick up items, shoot, and open
   doors.

   MOVING
   At first, you might find yourself bumping into walls while
   demons beat on you. Once you've got movement down,
   everything else follows.

   WALKING: Use the up and down arrow keys to walk forward and
   backward.

   TURNING: The left and right arrow keys turn you left and
   right.




                                        page 6

   RUNNING: Hold down the right Shift key and the appropriate
   arrow key to speed yourself up.

   STRAFE: By holding down the Alt key and the right or left
   arrow key, you can sidestep, rather than turn left or right.

   JOYSTICK OR MOUSE:If you are using a joystick, use button 1
   to shoot and button 2 to open doors and activate switches.
   Gravis PC Gamepads have a third and fourth button. These can
   be used as a Strafe and a Run button, respectively. If you
   are using a mouse, use button 1 to shoot and button 2 to
   walk forward. Double-click button 2 to open doors and
   activate switches. With a three-button mouse, use the third
   button to strafe.

   PICKING UP STUFF
   To pick up an object, just walk over it. You're smart, and
   know if you need to take it.

   -------------------------------------------------------------
   USING DOORS, SWITCHES & ELEVATORS
   -------------------------------------------------------------
   To open most doors and operate switches, stand directly in
   front of them and press the Spacebar. When you successfully
   operate a switch, it will change in some way (lights up,
   flips a handle, etc). If a switch does not change after a
   couple of tries, it is probably assigned to do a task that
   cannot yet be accomplished.

   LOCKED DOORS: Some doors have security locks, and require
   you to have a color coded (yellow, red, and blue) security
   card or skull key to open them. Other locked doors are
   operated by a switch on a nearby wall. Rather than walking
   up to the door, you'll need to operate the switch.

   HIDDEN DOORS: Some doors are hidden. Many of these can be
   opened by finding a switch. In some cases you just need to
   walk up to the wall and press the Spacebar. If you've found
   a secret door, it will open for you. There are clues that
   reveal a secret door--a wall that's shifted down or a
   different color, a flashing light on a wall, etc.

   ELEVATORS: You'll see platforms that raise and lower. Some
   platforms operate continuously, while others must be
   activated. Some of them sense your proximity and lower
   automatically. Others have a nearby switch. Those without a
   switch can usually be operated by walking up to the platform
   and pressing the Spacebar.

   TELEPORTERS: Teleporters can be identified by an evil red
   symbol on the floor beneath them. To use a teleporter, walk
   over the symbol.

   -------------------------------------------------------------



                                        page 7

   COMPLETING AN AREA
   -------------------------------------------------------------
   At the end of each area in DOOM there is an exit chamber,
   generally marked by a special door or an "EXIT" sign. Enter
   this chamber and press the switch inside to exit the area
   and head onward.  When you finish an area, an Achievement
   Screen tallies your performance. Hidden regions located,
   ratio of kills, percentage of treasure found, your
   completion time, and a par completion time are all
   displayed.

   ETERNAL LIFE AFTER DEATH
   If you die, you restart the level at the beginning with a
   pistol and some bullets. You have no "lives" limit--you can
   keep restarting the level as often as you're killed. The
   entire level is restarted from scratch, too. Monsters you
   killed before are back again, just like you.

   -------------------------------------------------------------
   FIREPOWER AND HOW TO USE IT
   -------------------------------------------------------------
   WEAPONS: At first, you have only your pistol and your fists
   for protection. When you run over a new weapon, you'll
   automatically equip yourself with it. As the game
   progresses, you'll need to choose between firearms. The
   numeric keys select particular weapons (you cannot use the
   keypad keys for this selection). The weapons are:

   1 = Fist

   2 = Pistol

   3 = Shotguns deliver a heavy punch at close range and a
   generous pelting from a distance.

   4 = Chainguns direct heavy firepower into your opponent,
   making him do the chaingun cha-cha.

   5 = Rocket Launchers deliver an explosive rocket that can
   turn several baddies inside-out.

   6 = Plasma Rifles shoot multiple rounds of plasma energy--
   frying some demon butt!

   7 = BFG 9000s are the prize of the military's arsenal. Great
   for clearing the room of those unwelcome guests. Shoot it
   and see for yourself.

   FIRING: To use a weapon, point it towards the enemy and
   press the Ctrl key, or hold down the Ctrl key for rapid
   fire. If your shots hit a bad guy, you'll see splattering
   blood. Don't worry if the enemy is higher or lower than you.
   If you can see a monster, you can shoot it.




                                        page 8

   AMMO: Different weapons use different types of ammo. When
   you run over ammo DOOM automatically loads the correct
   weapon.

   You have a maximum limit on the amount of ammo you can
   carry, too. These are listed on the right side of your
   status bar. Also, when you find a weapon that you already
   possess, don't scorn it! Picking it up also gives you ammo.

   TIP: When you're comfortable playing the game, try using the
   keyboard and the mouse simultaneously. The mouse provides
   fine control for aiming your weapon (allowing you to
   smoothly rotate right and left) while the keyboard permits
   you to activate the many useful functions of the game.

   -------------------------------------------------------------
   DANGEROUS DOOM ENVIRONMENT
   -------------------------------------------------------------
   Some parts of the DOOM environment can be more dangerous
   than the monsters you'll face. Areas containing exploding
   barrels, radioactive waste, or crushing ceilings should be
   approached with caution.

   EXPLODING BARRELS: Scattered around the base are drums
   containing fuel, toxic waste, or some other volatile
   substance. If your shots hit one of these barrels, it's
   kablooey time! It might take several bullets to set off a
   barrel, but a single blast of any of the other weapons
   usually does the trick.

   SLIME AND OTHER RADIOACTIVE WASTE: Many of the areas in DOOM
   contain pools of dangerous liquids that will damage you if
   you walk through them. There are several varieties of waste,
   each doing an increasing amount of damage. If it looks
   fluid, beware!

   CRUSHING CEILINGS: Some of the ceilings in DOOM can smash
   you, making you cry blood. Often you'll be able to see the
   ceiling moving before you go under it, but not always. Be
   careful and Save often!

   TIP: Barrels can often be the most devastating weapon in
   your arsenal--delivering a body-blasting explosion to all
   nearby purgatory pedestrians. Wait until several evil guys
   get next to a barrel and blast away at the can, then watch
   'em all go boom!

   -------------------------------------------------------------
   HEALTH AND ARMOR
   -------------------------------------------------------------
   Even for a tough hombre like you, DOOM can be a deadly
   place. Whenever you are injured, the screen will flash red,
   and your health will decrease. Keep an eye on your health or
   you'll end up face down.



                                        page 9


   HEALING: When you're hurt, you'll want to get healed back up
   as soon as possible. Fortunately, Medikits and Stimpacks are
   frequently scattered around the base. Grab them if possible.

   Stimpacks give you a quick injection of booster enzymes that
   make you feel like a new man--at least, to a degree.

   Medikits are even better, and include bandages, antitoxins,
   and other medical supplies to make you feel a lot healthier.

   ARMOR: Two types of body armor can be found laying around.
   Both reduce damage done to you. Unfortunately, both
   deteriorate with use, and eventually are destroyed by enemy
   attacks, leaving you in need of replacement armor.

   Security armor (green) is a light weight kevlar vest that's
   perfect for riot control.

   Combat armor (blue) is a heavy duty jacket composed of a
   titanium derivative--useful for protection against real
   firepower, like the kind you're gonna face.  If you're
   wearing armor, you only pick up a replacement suit if it
   provides more protection than what you're now wearing.

   -------------------------------------------------------------
   POWER-UPS
   -------------------------------------------------------------
   Other bits of "challenging electronics" may be found in
   DOOM. Most of these are pretty doggone handy, so grab them
   when able. These special items have a duration of either the
   entire level, a specific amount of time, or just provide an
   instant benefit. A few of them affect your game screen so
   you can tell when they are active. For example, when you
   pick up a radiation suit, the game screen turns green. As
   the suit deteriorates the screen will flash. This is a hint
   to get out of the radioactive ooze now!

   Radiation Suits provide protection against radioactivity,
   heat, and other low-intensity forms of energy. Basically,
   these suits enable you to wade through the radioactive ooze
   without taking damage. While a suit holds out, your screen
   will have a greenish tint. Duration: Time Based

   Berserk Packs heal you, plus act as a super-adrenaline rush,
   enormously boosting your muscle power. Since you're already
   a pretty meaty guy, this enhanced strength lets you tear
   ordinary dolts limb from limb, and you can even splatter
   those demons without too much trouble. However, you've got
   to use your Fist attack to get the benefit of the Berserk
   attack bonus. When you become Berserk, your screen will
   briefly turn red. Duration: One Level

   Backpacks increase the amount of ammo you can carry. In



                                        page 10

   addition, whenever you find a backpack, you receive extra
   ammunition.

   Computer Maps are a handy find, updating your Automap with a
   complete map to the entire area, including all secret or
   hidden areas. Areas you haven't been to are mapped in grey.
   Duration: One Level

   Light Amplification Visors allow you to see clearly even in
   pitch dark. Duration: Time Based

   -------------------------------------------------------------
   ARTIFACTS
   -------------------------------------------------------------
   A few artifacts from the other dimension are now laying
   around and you may want them, too.

   Health Potions provide a small boost to your health even
   past your normal 100%!

   Spiritual Armor provides a little extra protection above and
   beyond your normal armor.

   Soul Spheres are rarely encountered objects that provide a
   large boost to your health. A close encounter with one of
   these and you'll feel healthier than ever!

   Blur Artifacts are strange orbs that make it difficult for
   others to spot you. The enemy can still see you, but most of
   their attacks will be less than accurate.
   Duration: Time Based

   Invulnerability Artifacts are products of the Anomaly that
   render you immune to all damage. Pretty cool, until the
   effect wears off. When you're invulnerable your screen will
   be white--your punishment for being tough.
   Duration: Time Based

   TIP: Create dissension among demons by maneuvering them into
   a crossfire. If a bad guy is hit by another demon, he'll
   turn his rage towards the poor jerk with the pitiful aim. If
   this happens, let 'em at each other--it's always best to let
   the bad guys do the work for you. (This isn't effective with
   projectiles fired between demons of the same form.)

   -------------------------------------------------------------
   THE ENEMY
   -------------------------------------------------------------
   From the very first moment you enter the door, till the last
   gunshot of the game, you'll be fighting a host of baddies.
   Some are just regular guys with a bad attitude, others are
   straight from Hell. Some of the monsters you'll face aren't
   shown here. Don't say we didn't warn you.




                                        page 11

   Former Humans (dudes in filth-covered combat suits): Just a
   few days ago, you were probably swapping war stories with
   one of these guys. Now it's time to swap some lead upside
   their head.

   Former Human Sergeants (dudes in black armor, also filthy):
   Same as above, but much meaner, and tougher. These walking
   shotguns provide you with a few extra holes if you're not
   careful!

   Imps (brown thorny hominids): You thought an imp was a cute
   little dude in a red suit with a pitchfork. Where did these
   brown bastards come from? They heave balls o' fire down your
   throat and take several bullets to die. It's time to find a
   weapon better than that pistol if you're going to face more
   than one of these S.O.B.s.

   Demons (pink horrors, vaguely humanoid): Sorta like a shaved
   gorilla, except with horns, a big head, lots of teeth, and
   harder to kill. Don't get too close or they'll rip your
   fraggin' head off.

   Spectres (vague, half-formed shapes): Great. Just what you
   needed. An invisible (nearly) monster.

   Lost Souls (flying skulls): Dumb. Tough. Flies. On fire.
   'Nuff said.

   Cacodemons (gigantic floating one-eyed heads): They float in
   the air, belch ball-lightning, and boast one Hell of a big
   mouth. You're toast if you get too close to these

   Barons of Hell (you'll know 'em when you see 'em): Tough as
   a dump truck and nearly as big, these goliaths are the worst

   DOOM ADDENDUM
   ------------------------------------------------------------
   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



                                        page 13

   to the system requirements listed below.

   -------------------------------------------------------------
   SYSTEM REQUIREMENTS
   -------------------------------------------------------------
   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.

   -------------------------------------------------------------
   MULTIPLAYER MODE
   -------------------------------------------------------------
   GETTING STARTED
   -------------------------------------------------------------
   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,
   skill 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.

   -------------------------------------------------------------
   MULTIPLAYER INSTRUCTIONS
   -------------------------------------------------------------
   Many of the rules for playing DOOM change for the



                                        page 14

   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
   parameter.

   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



                                        page 15

   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.

   -------------------------------------------------------------
   COOPERATIVE OR DEATHMATCH MODE
   -------------------------------------------------------------
   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.

   -------------------------------------------------------------
   DEATHMATCH MODE GAMEPLAY NOTES
   -------------------------------------------------------------
   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.

   -------------------------------------------------------------
   RUNNING DOOM FROM THE COMMAND LINE
   -------------------------------------------------------------
   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.

   NETWORK PLAY
   ------------
   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>

   MODEM PLAY
   ----------
   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.
   -answer

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



                                        page 17

   -com1

   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."

   VERY IMPORTANT!
   If you're using a modem, 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:
           * Sets your modem to work at 9600 baud
           * 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.

   If the modem connection isn't working when you call your friend,
   have him call you instead.  Try setting the first line of your
   MODEM.CFG to "AT Z" with no parameters if that still doesn't work.

   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.

   GENERAL PARAMETERS
   ------------------
   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



                                        page 18

   default to the Cooperative mode.
   -deathmatch

   -SKILL sets the skill level (1-5) you wish to play.
   -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.
   -nomonsters

   -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.
   -respawn

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

   -------------------------------------------------------------
   TROUBLESHOOTING ADDENDUM
   -------------------------------------------------------------
   If you require technical assistance to run DOOM, call id
   Software's technical support line at (214) 613-0132 or
   e-mailing help@idsoftware.com.

   If possible, please be near your computer when calling id
   Software's technical support. Please have information
   regarding your system setup and configuration available.

   Before changing your system or software setup we recommend
   that you review your system manuals to ensure that your
   modifications will not endanger any existing information or
   hardware on you system or network. Modifying your system or
   your software setup can be dangerous, and we cannot help you
   with any resulting problems.

   -------------------------------------------------------------
   When DOOM runs, I get an "Insufficient Memory" error or DOOM
   just doesn't run.




                                        page 19

   You don't have enough free RAM to run DOOM.  This usually
   happens with 4Mb RAM machines -- you need about 3Mb of free
   RAM to run DOOM. If you have DOS 6 or later, boot your system
   and hold the left-shift key as the "Starting MS-DOS..."
   message appears. This will bare-boot your system and you must
   change to the DOOM directory and run DOOM. Your best bet is
   to make a CONFIG.SYS menu for a custom DOOM boot -- see
   page 97 in your MS-DOS 6 User's Manual.
   If you have DOS 5.0 or earlier, you must create a bare boot disk.

   Note: Do not use memory managers like EMM386, QEMM, etc.
   Do not use disk caching programs like SMARTDRV, etc.

   -------------------------------------------------------------
   I get a "WRITE ERROR" while DOOM is decompressing.

   You are using a disk compression program such as STACKER or
   DOUBLESPACE. These utilities try to make an "educated" <ahem>
   guess as to how much disk space you have left.  Obviously,
   they're wrong.  Delete some big games that are chewing up
   hard drive space, like any Wolf-alikes. :)

   -------------------------------------------------------------
   The Windows SETUP program runs after installation.

   DOOM did not install to your hard drive, probably due to
   insufficient disk space.  See above answer for a solution.

   -------------------------------------------------------------
   My GUS doesn't work.

   The default IRQ for a GUS is 11. DOOM doesn't handle IRQ's
   above 7.  Change this with your GUS setup program.

   -------------------------------------------------------------
   I can't get digital sound from my Sound Blaster compatible
   sound card.

   You are experiencing a DMA conflict. You may have a CD-ROM
   or hard drive on the same DMA channel that you specified in
   DOOM's SETUP program. Change the DMA channel of the sound
   card or offending device.

   -------------------------------------------------------------
   DOOM locks up.

   You need to turn "Hidden Refresh" off in your CMOS Advanced
   Chipset settings. If you're using RAMBIOS.SYS, you must
   remove it from your CONFIG.SYS. Make sure you also turn off
   any Hardware Video Shadowing (also found in CMOS settings.)

   -------------------------------------------------------------
   I hear static when listening to DOOM with my Sound Blaster
   (or compatible) card.



                                        page 20


   Run SBP-MIX (in your SBPRO directory) and turn down Line and
   Mic volumes to 0.

   -------------------------------------------------------------
   I still hear static, or my sound effects are breaking up.

   Disconnect any parallel port devices. (Sound cards,
   to work with DOOM, must use IRQ5 or IRQ7, which are
   used by LPT2 and LPT1 -- where printers are connected.)

   -------------------------------------------------------------
   I can't get sound on my ATI Stereo FX card.

   Contact ATI for a BIOS upgrade.

   -------------------------------------------------------------
   DOOM is too dark to see anything.

   On some monitors, DOOM may be too dark to play. Press F-11
   to improve the view.

   -------------------------------------------------------------
   Why can't I get music or sound effects?

   If you're not hearing sound effects and/or music, DOOM may
   have incorrect information regarding your sound card. Run
   the SETUP program to check if DOOM has the correct
   information on your sound card.

   Note: DOOM only supports IRQ numbers which or 7 or below.
   Be sure you set your sound card to an IRQ number which
   is 7 or below. Refer to your sound card manual for details
   on setting your IRQ number.

   Note: This is particularly important for Gravis Ultra Sound
   users because the standard default for the GUS card is 11.

   --------------------------------------------------------------
   How can I run DOOM under OS/2?

   The ideal DOOM-OS/2 system is a 486 with at least 8MB of
   RAM. In order to get DOOM up and running, first copy a
   program object to the desktop from the templates folder. For
   details on this procedure, please refer to your OS/2 Manual.
   Once you have the program path and optional command line
   arguments set up for the program object, you will need to
   edit the DOS session settings.

   Once you have the program path and optional command line arguments
   set up for the program object, you will need to edit the DOS session
   settings. DOOM will NOT run in a DOS window.

   During startup, the DOOM startup stops at "looking for player..."

   This occurs when you enter a number of players greater than
   the amount of players actually entering the game. For
   example, if you only have three players playing, but you
   tell DOOM to expect four players, it will wait until the
   fourth player starts the game. Press ESC to exit and restart
   the game with the correct number of players.

   -------------------------------------------------------------
   I'm receiving the error, "IPX NETWORK NOT DETECTED."

   Currently, DOOM only supports a network that uses the IPX
   protocol. If you receive this message, check your network
   manual to ensure your network uses the IPX protocol.

   -------------------------------------------------------------
   I've received the message, "CONSISTENCY FAILURE" while
   running DOOM.

   For DOOM to run properly as a multiplayer game, all of the
   machines that are running DOOM must maintain a nearly
   identical status of the game during network play. If you
   receive this message, something has occurred which caused
   the multiplayer game on one computer to be different from
   the multiplayer games running on the other systems. If this
   occurs, all of the players must quit from DOOM and restart
   the game.

   -------------------------------------------------------------
   Why can't I get DOOM to run as a multiplayer game?

   If someone else is running DOOM in multiplayer you may
   receive a network port conflict. From the SETUP program,
   change DOOM to run under a different port. Consult with the
   person in charge of your network to receive a valid port
   address.

   Why isn't the animation smooth?

   If the animation isn't running smoothly on your system you
   should try reducing the window size and/or play DOOM in LOW
   DETAIL mode. Refer to your DOOM manual for instructions on
   these options.

   -------------------------------------------------------------
   Why doesn't my mouse work with DOOM?

   If you renamed or commented-out information in your
   AUTOEXEC.BAT you may have removed the command which loads
   your mouse driver. Loading your mouse driver into DOS can be
   as simple as typing MOUSE and pressing ENTER at the command
   prompt.

   -------------------------------------------------------------
   Why can't I find a plasma rifle, BFG 9000, Berserk power-up,
   or invulnerability power-up?

   Unless you are playing Episode 2 or 3 you will not be able
   to find any of the above items.

   UPDATES TO THE MANUAL
