Installing DOOM

The minimum system required for playing DOOM is:

 486 processor operating at a minimum of 50Mhz

 8 meg RAM

 a 256 color video adaptor

 Microsoft Windows 95

You can also take advantage of:

 a Windows 95 compatible sound card

 a modem with at least a 9600 baud setting

 a TCP/IP or SPX/IPX network

All these devices must be set up to work with Microsoft Windows 95. If, for example, you have problems with sound, you should work with the basic Windows configuration of your sound card (in the Control panel) to get things working.

To install from Windows 95:

If your system supports AutoPlay

Simply insert the CD into your computer [image] the setup program will start automatically.

If your system does not support AutoPlay, or you have disabled AutoPlay

Insert the CD into your computer.  Open the control panel and double-click the Add/Remove Programs icon:

Press the Install button and follow the directions as presented.


Uninstalling DOOM

In the unlikely event you should ever want to remove DOOM from your computer, you should resist the temptation to simply delete the files from your disk manually.  Instead, use the built in capabilities of Windows 95 to perform a cleaner, more comprehensive uninstall. Open the control panel and double-click the Add/Remove Programs icon:

Select DOOM from the list of applications, press the Add/Remove button, and confirm the removal of DOOM.


Reinstalling DOOM

If you should inadvertantly remove a necesssary DOOM file from your computer and need to reinstall, you should first perform an uninstall, then install a fresh copy.

Controlling The Action

Most of the play commands in DOOM are a simple keypress away. You can use your keyboard, mouse, joystick, and combinations 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.

USING DOORS, SWITCHES & ELEVATORS

To open most doors and operate switches, stand directly in front of them and press the Open Key.

PICKING UP STUFF

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

COMPLETING AN AREA

At the end of each area in DOOM there is an exit chamber. 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 [image] 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.


Moving
Moving Around

Walking: Use the Forward and Backward keys to move in the direction you are facing.

Turning: The Left and Right keys turn you left and right.

Running: Hold down the Speed Key and the appropriate arrow key to speed yourself up.

Strafe: There are two ways to sidestep: use the Strafe Left and Strafe Right keys or use the Strafe key along with the Turning keys.

Note:	Jumping is very important for successfully completing DOOM. Though there is no Jump Key, you can leap from ledges by getting a running start. The faster you are moving the further you will go.

Mouse Control: If you are using a mouse, the default setting is to use your Left Button to shoot and Right Button to walk forward. Double-click the Right Button to open doors and activate switches. On a three-button mouse, use your Middle Button to strafe and double-click it to use doors and switches. The button configuration is set in the Launcher using the Configuration dialog.


Using Doors, Switches & Elevators
Doors, Switches & Elevators

(These objects all have many different appearances)

SWITCHES: 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 security card [image] [image] [image] or skull key [image] [image] [image] 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 Use Key. If you've found a secret door, it will open for you. There are clues that reveal a secret door [image] 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 Use Key

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

On-Screen Information

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

THE STATUS BAR

(click and explore)

MESSAGES

Often you 'II find yourself running over various items. DOOM tells you what you're picking up by printing a message at the top of the screen [image] unless messages are off. Pressing RETURN will display the last message.

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.

MOVING IN THE AUTOMAP:

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.


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


Status Bar: Health
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!


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


Status Bar: Your Mug
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.


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


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


Status Bar: Ammo Count
AMMO: This shows how much of each type of ammo you're carrying and the maximum amount you could carry [image] if you had it.


The Doom II Menu
Using The DOOM Menus

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.

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.

If you want to jump into the action, select this. DOOM will ask you to set the difficulty level. Each difficulty level differs in the toughness of the enemies you'll face.

Goes to a menu of various game settings.

 (F3)

 (F2)

Games can be saved or loaded at any time during the gameplay. To save a game, move the skull cursor to any 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.

 (F10)

Quit Game enables you to quit from DOOM and return to Windows.


The Options Menu

 (F7)

This allows you to end the current game without exiting to Windows or loading a new game.

 (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.

This option is not operational in DOOM for Windows.  To set the level of screen detail, use the Advanced Dialog of the Launcher before the game begins, or the Alt - and Alt = keys during the game.

 (+ and -)

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 viewing area. A smaller viewing area increases the smoothness of the animation on slower systems.

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.

 (F4)

This takes you to another menu where you can adjust the music and sound effects volume.

 (F11)

On some monitors, DOOM may appear too dark. Press the function key, F11 to lighten the screen through five different brightness levels.


The Difficulty Levels

An easy romp through the playground.  Not many monsters here.  This is good when you're learning the controls.

This is good when you know how it works, but you still panic too much.  Panic is a bad thing when you're surrounded by evil.

The demons are out in force and they'll take great pleasure in hurting you as much as you let them.

So you think you're tough? Prove it!

This is for those times when killing a guy once just isn't enough. If you're lucky, you'll wake up...


The Sound Menu
The Volume Menu

This selection has a bar with a sliding marker, allowing adjustment of the sound effects volume from "off" to "maximum."

This selection also has a bar with a sliding marker, allowing adjustment of the music volume.


The Launcher Program

DOOM has a number of options that can only be set when it is started.  The launcher allows you to set these options and start single or multi-player games.  The Launcher also provides access to the Configuration Dialog, which allows you to personalize DOOM to your preferences, and the Advanced Dialog, which allows you to specify advanced game options.

Multi-Player Instructions

Many of the rules for playing DOOM change for the multi-player game. Read the following information carefully before you begin to play DOOM in multi-player 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 save game during a network game, it saves on every player's system in the save game 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 multi-player game. To load a game everyone must quit from the current game and restart the game from the saved game, which is specified using the Launcher.

WEAPONS: When a player runs over a weapon he picks it up, but the weapon remains in the game for other players to take.

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 multi-player 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 multi-player game you can communicate with other players in the Chat mode. To enter into Chat 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 multi-player game, you can send your own pre-defined macros (defined in the Launcher program) by initiating Chat mode (as described 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 multi-player [image] 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 using the Launcher. 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 [image] 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.


Tip: Crossfire
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 [image] 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.)


Tip: Automap
TIP: When travelling narrow passages many players have found it useful to examine the Automap in a magnified mode enabling them to see exactly where to step.


Tip: Save Often
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.


Tip: Use Both Controls
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 or left) while the keyboard permits you to activate the many useful functions of the game.


Tip: Use The Barrels
TIP: Barrels can often be the most devastating weapon in your arsenal [image] 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!


Tip: Using Healing Kits
TIP: Medikits and Stimpacks only improve your health up to 100%. Careful usage will let you take full advantage of their healing power.


Title Screen

Welcome to DOOM, a lightning-fast virtual reality adventure where you are 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 [image] using your wits is IMPORTANT.  To escape DOOM, you need both brains and the killer instinct.


The Doom Story
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 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 [image] 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. They know you're here. There's no turning back now.


Dangerous Environment
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!

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.

*Not included in the shareware version.


The Enemy: Former Humans
Former Human: 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.


The Enemy: Former Human Sergeants
Former Human Sergeant: Same as the Former Humans, but much meaner, and tougher. These walking shotguns provide you with a few extra holes if you're not careful!


The Enemy: Imp
Imp: 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.


The Enemy: Demon
Demon: 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.


The Enemy: Spectre
Spectre: Great. Just what you needed. An invisible (nearly) monster.


The Enemy: Lost Soul
Lost Soul: Dumb. Tough. Flies. On fire. 'Nuff said. (Not included in the shareware version.)


The Enemy: Cacodemon
Cacodemon: 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 monstrosities. (Not included in the shareware version.)


The Enemy: Baron of Hell
Baron of Hell: Tough as a dump truck and nearly as big, these goliaths are the worst thing on two legs since Tyrannosaurus Rex.


The Enemy: The Spider Mastermind
The Spider Mastermind: You guess the Arachnotrons had to come from somewhere. Hi, mom. She doesn't have a plasma gun, so thank heaven for small favors. Instead, she has a super-chaingun. Crap.


The Enemy: The Cyberdemon
The Cyberdemon: A missile-launching skyscraper with goat legs. 'Nuff said.


Fire Power
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).

1 =		4 =
		5 =
2 =		6*=
3 =		7*=

*Not included in the shareware version.

FIRING: To use a weapon, point it towards the enemy and press the Fire Key, or hold down the Fire 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. lf you can see a monster, you can shoot it.

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

Artifacts

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


Health Potion
Health Potions provide a small boost to your health [image] even past your normal 100%!


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


Soul Sphere
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 Artifact
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 Artifact
Invulnerability Artifacts render you immune to all damage. Pretty cool, until the effect wears off. When you're invulnerable your screen will be white [image] your punishment for being tough.

Duration: Time Based


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.

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

ARMOR: Two types of body armor can be found laying around, Security Armor and Combat Armor. 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.

If you're wearing armor, you only pick up a replacement suit if it provides more protection than what you're now wearing.


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


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


Security Armor
Security armor is a lightweight kevlar vest that's perfect for riot control.


Combat Armor
Combat armor is a heavy duty jacket composed of a titanium derivative useful for protection against real firepower, like the kind you're gonna face.


Faces


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 Suit
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 Pack
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


Backpack
Backpacks increase the amount of ammo you can carry. In addition, whenever you find a backpack, you receive extra ammunition.

Duration: Until You Die


Computer Map
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
