1.  	PLAYING DESCENT! 

The year is 2132.  You are an outside contractor working for the Post Terran Minerals Corporation, a company known for its power, technology, and shameless materialism.  Rumor has it the untouchable PTMC has a serious problem with its planetary mining network... you are ordered to report for a briefing...

Descent is a heart-pounding, gun-wrenching, edge-of-your-seat experience. Following is a few pointers on how to easily get inside and move around the Descent universe.

1a. 	System Requirements

BARE REQUIREMENTS:
	- IBM PC compatible 386-33 or faster
	- 4 MB RAM
	- DOS 5.0 or greater

STRONGLY RECOMMENDED:
	- 486 or Pentium processor
	- 8 MB RAM
	- stereo 16-bit soundcard with General MIDI support
	- a quality joystick

1b. 	Installation & Setup 

To install Descent, use PKUNZIP to unzip the distributed files into a temporary directory.  From that directory, type:

INSTALL <ENTER>

The Installer will uncompress and assemble the needed files.  It will then run SETUP to allow you to configure your sound card(s).

To change soundcard configuration at any time, you can also type:

SETUP <ENTER>

Follow the prompts to configure your sound device(s).  Be sure you test the sound and music!  If soundcard settings are incorrect, Descent may not work properly or even fail.

To start Descent type:

DESCENT <ENTER>

After starting the game, you will be prompted to enter your PTMC pilot name.  This will be the name Descent uses to store your control configurations and for tracking you in Multiplayer games and in high scores.

1c. Menus 

Use the arrow keys to move around menus in Descent.  Unless otherwise noted, hitting <ESC> will accept the current menu's settings and return to the previous one.  Some menus contain radio-type switches and checkboxes that can be toggled by hitting <SPACEBAR>.  From the game you can always hit the <F1> key to bring up a list of Game Options.

DESCENT MENU
--------------------------

NEW GAME - Start a new game of Descent.  You may begin on any level you have reached in previous games.
  
LOAD GAME - Resume a previously saved game.  Saved games are stored in your pilot file, so be sure the proper pilot is selected.

MULTIPLAYER - Allows you to start a game of Multiplayer Descent using a modem, serial cable, or IPX network.  See Section 3 for details.

OPTIONS - Takes you to the Options Menu (see below).

CHANGE PILOTS - Allows you to change the current pilot or create a new one.  All control configurations and saved games are stored in your pilot file.

VIEW DEMO - Lets you play a recorded demo file.  See section 5 for details.

HIGH SCORES - See Descent High Scores.

ORDERING INFO - Shows how to order the full registered/commercial version of Descent!

CREDITS - See the list of people who created Descent.

QUIT - This will return you to DOS.

OPTIONS MENU
-------------------------

FX VOLUME - Changes volume of sound effects.

MUSIC VOLUME - Changes volume of the music.

REVERSE STEREO - Allows you to reverse the stereo sound channels.  This is sometimes necessary for earphones, speakers, or extension cables that are wired incorrectly.

BRIGHTNESS - Some monitors are darker than others.  If you have trouble seeing details on your game screen, try adjusting this slider.

CONTROLS - Takes you to the Controls Menu (see below).

DETAIL LEVELS - Allows you to adjust the Detail Level of Descent (see below).

CALIBRATE JOYSTICK - If your joystick drifts, you probably need to calibrate it.  Also available in the game by hitting <F4>.

JOYSTICK SENSITIVITY - Adjusts the responsiveness of your joystick controls.

SHIP AUTOLEVELING - If this is on, your PyroGX ship will attempt to align itself with the curvature of the mine tunnels.  This is useful for first-time Descent players, but may be turned off once you're accustomed to full 3D flight.

CONTROLS
-----------------

>> NOTE:  	See REFCARD.TXT in your Descent directory for a list of the
>>       		default keyboard controls.  If you have a printer, you can also use
>>       		the Paintbrush utility in Windows to print the file REFCARD.PCX.

The Controls menu allows you to choose your prefered controls for Descent. If you are using a Thrustmaster stick, the Gravis Phoenix, or a Logitech CyberMan, see Section 4.

By choosing Customize Keyboard you can change the default keys to your preferences.  Any changes are saved in your pilot file.  If you use a Thrustmaster WCS, FLCS, or Gravis Phoenix, you should keep the keyboard configuration in its default setup and alter the appropriate downloadable device file.

DETAIL LEVELS
-------------------------

If you are running on less than a 486-50 with 8 MB RAM, you may wish to lower your detail level to achieve better performance.  There are several preset detail levels available to you, as well as a Custom Detail Level. The following is a list of options available under the Options/Details/Custom menu:

OBJECT COMPLEXITY:  This affects the number of polygons used by objects like robots, player ships, and other 3D objects.  Lower values will increase speed, but simplify the shapes of many objects.

OBJECT DETAIL:  This determines at what distance an object changes from flat-shaded to texture-mapped details.  Setting this slider to a lower value will cause robots to be flat-shaded much closer.

WALL DETAIL:  This option determines at what distance walls appear flat-shaded vs. texture-mapped.  It also affects the accuracy vs. speed of the texture mapper.  If you notice wall textures "sliding" or "jumping" a little in the distance, this slider is set too low.

WALL RENDER DEPTH:  This will change the maximum distance you can see. Lower settings will increase the speed of Descent, but will cause flat-colored "walls" to appear across long hallways.  These boundaries do not affect weapons or other objects, only your visuals.

AMOUNT OF DEBRIS:  Changing this slider will determine how much debris is made when robots explode.  Setting this to a low value will make fewer pieces in heavy combat.

SOUND CHANNELS:  Sound can have an affect on the speed of your game as well.  This slider will change the maximum number of sounds that can be played at once.

1d. Powerups

ACCESS KEYS:  These access keys give you access to the different security levels of the mines.  They are color-coded to the doors they open.

ENERGY BOOST:  This will give your energy banks a boost, up to 200 units max.  Energy Centers can deliver recharge up to 100 units.

SHIELD BOOST:  This will give your ship's shields a kick.  By getting shield powerups, you can get your shields up to a maximum of 200 units.

CLOAKING DEVICE:  Gives your ship cloaking ability for a limited time.

INVULNERABILITY:  Makes your ship invulnerable for a short time.

EXTRA LIFE:  Gives you a bonus life.

LASER: Laser cannons have four power levels.  The laser powerup will give you the next available level.

QUAD LASER:  This powerup will modify your existing laser system to fire four bolts instead of the standard two.

VULCAN CANNON:  This weapon rapidly fires explosive-tipped shells.

VULCAN AMMO:  This gives you more ammunition for the Vulcan Cannon.

SPREADFIRE CANNON:  This fires a spread of energy at your target.

* PLASMA CANNON:  Fires bursts of supercharged plasma.

* FUSION CANNON:  Fires destructive blasts of energy directly from the ship's fusion reactor.  Capable of punching through large crowds of robots before running out of power.

CONCUSSION MISSILES:  All-purpose dumbfire rockets.  Come singly or in packs of four.

HOMING MISSILES:  Same size warhead as Concussion Missiles, these are equipped with a tracking device that can follow a target around most turns.  Come singly or in packs of four.

PROXIMITY BOMBS:  These bombs are launched behind your ship, waiting to explode when something gets near.  Can be armed as a secondary weapon, or dropped directly by hitting the default key "B".

* SMART MISSILE:  When this missile detonates, it sends bomblets of heated plasma after the surrounding targets.

* MEGA MISSILE:  Stand back when you launch this earthshaker.

* These four weapons are only available in the registered/commercial version of DESCENT.  See ORDERFRM.TXT for details.

1e. Doors

Doors in the PTMC mines can be opened by shooting them or bumping them. If a door is locked, it needs the appropriately colored access key. If a door is not color coded and cannot be opened, it is a special door that may open by a motion sensor somewhere in the mine.

1f. PTMC Mine Centers

ENERGY CENTER:  Designed for "on the fly" replenishing of robot's power cells, it will also recharge your own.  These will charge your ship's energy banks (up to 100 units).

ROBOT GENERATOR:  Automated centers that determine a mine's needs and assemble robots from surrounding minerals and metals.  Very dangerous.  Identifiable by its violet color.

MAIN REACTOR:  The power generator of the whole mine.  Usually in a secluded place away from day-to-day mine mishaps.

2. 	TIPS for NEW PILOTS

Here are a few things that help new players adjust to the fully 3D world and intelligent robots of Descent.  Heed these tips and you'll soon be blasting robot hordes (and your friends!) with ease.

+	Use a quality joystick.  Thrustmaster, Advanced Gravis, and CH Products provide full lines of controls well suited to 3D flying.

+	If you use a two-button joystick, try keeping one hand on the A and Z keys to control your FORWARD and REVERSE.

+	If you're up against a wall, try using REVERSE to back away instead of turning around.

+	Learn how to SLIDE well.  Using vertical sliding instead of pitching will help keep you upright.  If your joystick has a Hat Switch, use it to slide.

+	Use SLIDE to evade enemy fire.  This will help keep the robots in your sights.

+	Sweep fire side-to-side to hit evading robots.  This is especially important on higher skill levels where robots evade faster.  Also try using lasers and missiles simultaneously against an evading robot.

+	Rescue the hostages!  If you rescue all hostages in a mine, you receive a full rescue bonus.  But be sure you make it out after picking them up - if your ship's destroyed, so are they.

+	Try clearing a path to the exit before you attack the Main Reactor. You may run out of time if you're battling hordes of robots on your escape!

+	The blast radius of a concussion missile is very effective against tight groups of robots.  

+	Look for secret doors.  Weapons and ammo are often behind them.  They can be a different color, or have small seams running down them.  Keep in mind, Descent is fully 3D, and secret doors aren't only in the walls...

+	DON'T SIT STILL.  The best way to stay alive is to keep moving. Using SLIDE to circle a target while you're firing is very effective.

+	Learn to use your ship's Automap.  It can reveal things your eyes may miss.

+	Flares can help sniff out cloaked robots & players.

3. 	Multiplayer Descent 

3a. 	Multiplayer: 
	Features/Rules
	>> NOTE:  ONLY ANARCHY MODE IS AVAILABLE IN SHAREWARE VERSION. <<
	>>  SEE ORDERFRM.TXT TO RECEIVE THE FULL DESCENT EXPERIENCE!   <<

There are several features available to players of Multiplayer Descent not used in normal single player games.  Here is the rundown:

Multiplayer Keys
------------------------

TEAMMATE ID DISPLAY (F6):  Available in Network Team games only.  If enabled, this will show a teammate's name if he is in your sights. Hitting F6 will turn this on/off.

KILL LIST DISPLAY (F7):  This toggles the Multiplayer Kill List on/off. In Network Team games, this alternates the display between Player Kills, Team Kills, and no kill display. 

SEND MESSAGE (F8):  Lets you type a message to other player(s).  Addressing the message to specific player(s) can be done by using a colon. For example, sending the message "ST:YOUR TIME IS NEAR!" will send the message "YOUR TIME IS NEAR!" to any players with "ST" as their name or first characters.  This would include the players STEVE or STACY.  If there is no address, the message will be sent to everyone.  If there is an address but no match, it will not be sent.  In Team Anarchy, addressing messages to "1:" or "2:" will send them only to Team 1 and Team 2, respectively.

TAUNT MACROS (F9-F12):  This works the same as above, but lets you send one of four predefined messages with one keypress.  By using SHIFT, you can define or re-define what F9-F12 will send.  For example, hitting SHIFT-F10 will let you change what F10 will send  when you hit it by itself.  Message addressing using ":" is available in macros as well (see above).  Taunt Macros are stored in your pilot file for future games.

Multiplayer Rules
-------------------------

Some special rules apply to Multiplayer Descent Games.  Here is the rundown:

+	When players are killed, they drop their weapons and powerups!  This also means that if there is only one Spreadfire Cannon placed in a level, only one player can have it at a time.  If you want a certain weapon, you may have to beat it out of someone!

+	When you fire secondary weapons in a multiplayer game, a new powerup of that type is created randomly somewhere in the mine.  This keeps the number of weapons in the game constant.  If you see a weapon suddenly appear in front of your ship, consider yourself lucky!  Cloak/Invulnerability replacements are created when these effects wear off of a player.  Concussion Missiles do not replace themselves.

+	Bringing up a menu in Multiplayer Descent does NOT stop the action.  Your ship is still vulnerable to attack.  If you need to spend time in a menu, find a place to hide.  If you're attacked while in a menu, the game will automatically return you to the game so you can defend yourself.  It will also return you from menus if the reactor is about to explode.

+	After finishing a level in Multiplayer Descent, there may be a waiting period while other players escape the mine.  Everyone will then enter the new mine together.  The waiting delay may be up to 60 seconds.  If you wish, you can exit the game entirely by hitting <ESC> at this screen.

3b. 	Multiplayer: 
	Modem/Serial Games
	
	>NOTE:  If you experience any problems, see Section 7 for troubleshooting tips and solutions.

Modem/Serial Setup
-----------------------------

Before attempting to start a Serial game, both users should check the Com Settings menu to verify that the options are correct.  Any changes are saved for future games.

NOTE:  Games using a null-modem cable require that both machines use the same baud rate in the Com Settings menu.  Modem games, however, do not require this.

If your machine has a 16450 UART, you should choose 9600 or 19200 baud.  The higher the baud rate, the better Descent will perform.  If your computer has a 16550 UART, you can use 38400 baud rate for optimum performance.  If you are unsure what type of UART your machine has, you can try selecting the 38400 baud rate option.  Descent will tell you if it does not detect the 16550 UART required for 38400.

For modem users, note that changing the baud rate in the Com Settings  menu actually sets the rate of communication between the computer and the modem.  Even though many modems do not support actual baud rates above 14400, it is still better to choose a 38400 baud rate in the menu. This will allow Descent to spend less time communicating with the modem, and will increase game performance.

Modem Descent requires at least a 9600 baud modem with an error correction protocol (preferably v.42).  Data compression is also helpful, and should be enabled in the modem (v.42bis is preferable).  The modem should respond to a drop in the DTR control line by hanging up.  Fortunately, most modern modems have adequate factory settings for playing Descent.

If you receive good performance at 9600 baud or above when using your modem for things like on-line services, no special initialization string should be necessary to run Descent ("ATZ" will do nicely).  If your modem is something more exotic, you may wish to use an init string of "AT&F"
to reset it to factory defaults, which should work great with Descent.

Connecting
----------------

	>> NOTE: If you are using a serial port with a non-standard IRQ, you will need to use the Custom option in the Com Settings menu.  Pressing return on this checkbox will allow you to change the settings.

Starting a game of Serial Descent is a two-stage procedure.  First, a link must be established between two machines.  This is accomplished differently depending on what type of game you are playing.

If you are establishing a null-modem cable link, both players must select "Establish Null-Modem Link" from the serial game menu.  After the two computers have established a connection over the null-modem cable you will be returned to the menu and should have new options available to you. If the two machines fail to achieve a link, check the serial parameters on both sides.  The baud rate settings must be identical on both sides for them to communicate properly. After establishing the null-modem link, one machine is designated as the master and the other is the slave.  This is not visible from the menu, but when you go to start game, only one of the two machines will prompt for the game settings to use.  See Starting a Game below for more information.

If you are starting a modem game,  One person must select Dial Modem from the serial game menu and the other must select Answer modem. After the modems connect, you will be returned to the serial game menu and new options will be available to you.

Starting
-----------

You should now see the "Start Game" option on your menu.  The blue line should indicate if you are connected or not.  When selecting Start Game, one player will be offered a menu of game options such as start level and game mode.  If a modem is being used, the person who dialed will need to choose the game options, while the other waits for him/her to start.  In null-modem games the starter is randomly determined.  After this, both players will be placed in the mine and the game begins.

After the game is finished or if one of the players decides to leave the game, both players are returned to the serial game menu.  The communication link is STILL ACTIVE, however.  If you want to play another game, perhaps with different settings or a different starting level, just select Start Game once again.  If you want to hangup the modem or release the null-modem connection, select Close Link.  

Another feature of the modem game is the ability to send messages back and forth between connected players before they are in the game.  You can do this by selecting Send Message from the Serial Game menu.  This option is only available once a connection has been established.  This is useful if you do not have an extra phone line for voice  communication while playing and you need to negotiate the terms of the  game.  Another feature is automatic notification when a game is starting.  If one player selects start game but the other does not, the person who didn't start will be informed that the other player is ready.  If the user isn't prepared to start yet, the first user will be notified.  

Make sure you select Close Link or exit the serial game menu if you're finished with the modem game.  If you do not, the modem will remain connected to the other player.

Phone Book
------------------

A small phonebook is available from the dial menu of the serial game menu.  This lets you store the names and phone numbers of your 8 most frequent opponents.  To edit the phonebook go to the Dial menu and select Edit Phonebook.

3c. 	Multiplayer:  
	Network Games

Netgame Requirements
----------------------------------

Descent is designed to run on networks using the IPX protocol.  To use IPX protocol on your LAN-connected PC, you must be loading the IPX.COM driver provided by Novell, in addition to lower-level drivers required by your particular brand of network card.

Shareware Descent requires that network players all be connected to the same local network so their packets can be routed directly without intermediate processing by routers.  The registered/Commercial version of Descent will support routing through network servers.

Netgame Setup
----------------------

Descent supports up to 4 simultaneous network games on a single socket.  If you need to run more than 4 games on a single LAN, players can use the -socket option to change to a different socket number.  Descent uses a default socket number of 5100(Hex).  The -socket option adds a value to this base, so '-socket 1' would tell Descent to use socket 5101(Hex).  This option can be used to avoid socket conflicts with other network services should they arise.

One person playing must select Start Netgame from the Multiplayer menu. The starting parameters are explained below:

Starting a Netgame
----------------------------
DESCRIPTION:  The name of the game, literally.  This is merely for other people will see this when they are choosing games to join.

LEVEL:  The level the game will start on.  Play may progress to other levels during the game.

MODE:  Determines type of game to be played:

	ANARCHY:  A human-only free-for-all battle to the death.  The goal is to accumulate the most kills.

   	* TEAM ANARCHY:  Same as Anarchy, but with teams.

	 ANARCHY with ROBOTS:  Same as Anarchy, but with robots thrown in.  The goal is still to kill your human opponents, but the robots have their own agenda... Robots are also a good source of powerups.

	* COOPERATIVE:  Humans vs. the robots.  Save humanity!

* Only Available in registered/commercial Descent.
  See ORDERFRM.TXT for details.

CLOSED GAME:  Determines whether or not new players will be allowed to join once the game has started.  If you have checked the Closed Game box, only the starting players will be in the game.  Note that even in Closed games, the starting players are allowed to leave Descent and rejoin at any time. 

DIFFICULTY:  This determines many factors from robot awareness and deadliness to time for mine destruction countdowns.  If the slider is to the left the game will be easier, to the right it will be harder.

Once parameters are set, hit <ENTER>.  The next screen is player selection.  As each player selects your game from the Join Game screen, his/her name will appear on your list.  By default, all players wishing to join will be selected, but you can deselect them by pressing the spacebar on their checkbox.  Press <ENTER> to start the action.

Team Selection
-----------------------
If you've chosen Team Anarchy mode, the next screen will be Team Selection. Team names can be modified in the text boxes.  Pressing <ENTER> on a player's name will move him/her to the other team.  Team 1 ships will be colored BLUE and Team 2 ships will be RED.  Press <ESC> to accept the teams and start the game.  

Joining a Netgame
---------------------------
Choose Join Netgame from the Multiplayer level.  The next screen will show you all active netgames on that socket.  Below each game is listed the current level number, number of people playing, and game status.  Netgame status can be:

	FORMING:  Game is in player-selection phase.  Anyone may attempt to join a forming netgame.

	OPEN:  This means the game is in progress, and you may join at any time.

	CLOSED:  The game is playing, but closed to new players.  This is because there are 8 players in the netgame already, or the game was started as Closed.

	BETWEEN LEVELS:  The game is in progress, but the players are rushing for the escape tunnel.  If you wait for the level to advance, it will change to JOIN and you can then hop in.  Closed netgames will never show this message.
       
Rejoining a Netgame
------------------------------

If you leave a netgame for any reason, you may rejoin the ongoing game when you're ready.  Although you lose accumulated items, you will retain your ship color and kill count (unless you've been gone long enough for someone new to have taken your spot).  Make sure you rejoin from the same computer using the same pilot name so the game knows you as a previously-joined player.

The person who started the game is also free to leave and re-join the game at will; there are no special restrictions for this person once the initial parameters have been chosen.

4. Thrustmaster controls, Gravis Phoenix and Logitech Cyberman   

Thrustmaster, Gravis Phoenix, and Logitech Cyberman controls are fully supported by Descent.  The device control files (DESCENT2.ADV, DESCENT.B50, DESCENT.M50, and DESCENT.PHX) can be found in your Descent directory. If you have a Wingman Extreme, you should use the Thrustmaster FCS option.

	Thrustmaster FCS:  Choose "Thrustmaster FCS" under Options/Controls.
    	Mark I/II       This is for players _not_ also using the WCS.  (when not used If you use the WCS throttle with the FCS, follow with WCS)  instructions for the WCS below.

	* Thrustmaster WCS:  Load the DESCENT2.ADV file into your WCS.  In
    	Mark II        Descent, choose "Joystick" under Options/Controls. Now choose "Configure Above" and change the THROTTLE entry to respond to the WCS (the Y2 axis). Also see special note in section 7 about the WCS.

	* Thrustmaster FLCS:  Load the DESCENT.B50 & .M50 files into your FLCS.  If you also use a WCS throttle, no program should be loaded into the WCS.

	Gravis Phoenix:  Load the DESCENT.PHX file into your Phoenix. In Descent, choose "Joystick" under Options/Controls. Now choose "Configure Above" and change the THROTTLE entry to respond to the throttle slider (the Y2 axis).

	Logitech Cyberman:  You must have the Cyberman SWIFT driver loaded before you run Descent.  See Cyberman docs for details.  

Calibration Note:  When using one of the analog throttles listed here or the CH Flightstick, you will be prompted to calibrate your throttle as well as your joystick.

*  >> NOTE TO WCS and FLCS USERS:  Because these devices intercept the keyboard signals, your ship may fly strangely when you also hold down keyboard keys (like 'A' and 'Z').  If you keep the WCS or FLCS on your system, it's recommended that you use those devices for throttle control and sliding, not the keyboard.

5. Demos & Screenshots 
Demos
----------

Descent has a fully integrated demo recording and playback system.  This recording will work in single or multiplayer games, so you can have a permanent record of blasting your friends to pieces.  Hitting F5 in the game will turn on recording.  Hitting it again will turn it off and prompt you for a filename.  If you press <ESC> from the filename box, the demo will NOT be saved.  The demos will record the advance from one level to the next; however, the escape sequences will be skipped in playback.

Demo files are saved in the Descent directory and have the filename extension ".DEM".  Of course, Descent DEM files may be distributed freely.

>>NOTE:  Descent .DEM files can become quite large on disk.  This is especially true when recording heavy combat.  Make sure you have adequate disk space before recording.  If you have less than 500k free on disk, you won't be allowed to record a demo.

To view a recorded demo, choose View Demo from the Descent menu.  During playback, the following keys are available:

Arrow keys:			Also:   SHIFT-LEFT ARROW  = fast reverse
                           	SHIFT-RIGHT ARROW = fast forward
					CTRL-LEFT ARROW   = go to start
         	play    		CTRL-RIGHT ARROW  = go to end
          	/\
         	||            	PRINT SCREEN      = save screenshot

  rewind <=      => forward

          	||
            	\/
         	stop

Certain gauges and other trivial items won't display accurately in demo playback in order to minimize the space needed for demo files.

Screenshots
------------------

Hitting the PRINT SCREEN key will save a screenshot.  The files are written to the Descent directory with the name convention SCREENxx.PCX. The number xx will automatically increment as long as you're in Descent. If you leave the game, then return, the numbering will start over and
overwrite existing screenshots.  The pictures are in .PCX format.

7. Troubleshooting & Common Problems 

Regardless of configuration, you should have no trouble running Descent. But in the unlikely case you do have problems, here are some helpful pointers:
      
General Problems
--------------------------
=> Q:  DESCENT RUNS SLOWLY ON MY MACHINE, ESPECIALLY IN LARGE BATTLES. WHAT CAN I DO?

A:  	Try putting your detail level on a lower setting.  Also try using F3 and +/- to change the size of the game window.  Lowering the number of available sound channels in Options/Detail/Custom menu can help significantly in large battles.

=> Q:  I HAVE A SMALL GAME WINDOW AND A LOW DETAIL LEVEL, BUT DESCENT STILL LOADS AND RUNS SLOWLY.

A:  	Check your sound card settings in SETUP.  Incorrect settings can cause significant slowdown.

=> Q:  THE WALLS IN MY GAME SEEM TO JUMP AROUND IN THE DISTANCE.  WHY?
=> Q:  I GET A COLORED WALL IN THE MIDDLE OF MY TUNNELS.  WHAT IS THIS?

A:  	These are due to the Detail Level being set below the highest setting.  See "Detail Levels" in Section 1.  

=> Q:  MY COMPUTER HAS 4 MEGS OF RAM.  THE GAME IS SLOW AND ACCESSES THE HARD DRIVE ALL THE TIME.

A:  	If you have less than 8 megs of RAM, try running a disk cache (even as small as 256k).  This can help immensely.  Also try using the "-lowmem" command line option when running Descent.  You might consider purchasing a memory upgrade.  Every meg of RAM you add will increase performance.

=> Q:  DESCENT LOCKS UP WHEN I RUN IT.

A:  	Try running Descent with the "-nosound" option.  If this works, then chances are it's a sound card problem.  Run SETUP and make sure your card settings are correct.  If you don't hear digital sounds or music when you test them in SETUP, try Autodetection.  If this doesn't help, refer to your sound card manual for troubleshooting instructions, or call Interplay Technical Support.    

=> Q:  DESCENT DOESN'T WORK WITH MY GRAVIS ULTRASOUND.  I HAVE MORE THAN 512K RAM ON MY GUS CARD, AND THE GAME HANGS WHEN LOADING PATCHES.

A:  In your Descent directory there is a file called DESCENTG.INI.  Edit this file with a text editor like DOS EDIT or BRIEF.  Change the third line to read: "O 768 8 22" instead of "O 768 8 44".  Also change the fourth line to read "O 1024 8 22" instead of "O 1024 8 44". This will force the patches to load in 22khz instead of 44khz, and should solve your problem.

=> Q:  MY COMPUTER LOCKS UP WHEN AUTODETECTING SOUND CARDS IN SETUP. WHAT'S WRONG?

A:  	Due to hardware conflicts, autodetecting for sound cards is a risky process.  If you know the brand, port address, IRQ, and DMA of your sound card(s), it is recommended that you manually configure these items.  Lockups are also common when autodetection is used when no sound cards are installed.

=> Q:  I CAN'T SELECT THE RIGHT PORT/IRQ/DMA FOR MY SOUNDCARD IN SETUP.

A:  	If the proper selections don't appear in the SETUP, then you can always select them manually by editing your DESCENT.CFG file located in your DESCENT directory.  While we tried to account for every possibility, some of the more exotic configurations may not be listed.  Contact Interplay if your setup is not listed.  

=> Q:  WHY DON'T I HEAR ANYTHING WHEN I TEST MY SOUND IN SETUP?

A:  You may have the wrong sound card selected, or incorrect port, IRQ or DMA settings.  Volume may be set too low in your sound drivers (or the volume slider on the back of your sound card). Hardware conflicts or loose cables may be to blame as well.
      
=> Q:  MY JOYSTICK ISN'T RESPONDING IN THE GAME.  WHAT'S WRONG?

A:  	Be sure you have JOYSTICK selected in the Options/Controls menu, and that it's calibrated.  If your joystick connects to your soundcard, make sure the joystick port jumper is ENABLED on the card. Some soundcards have this disabled by default.

=> Q:  HEY!  SOME OF MY POWERUPS DISAPPEARED.  WHAT HAPPENED?

Certain powerups will remove themselves from the game if they have been around 4 or 5 minutes.  This only happens to Concussion Missiles, Energy, and Shield powerups dropped by a dead player.
    
=> Q:  WHY DOES DESCENT ACT STRANGELY WHEN I RUN IT UNDER WINDOWS?

A:  	While Descent may run under Windows, it isn't recommended.  You will probably get odd behavior and slowdowns due to timer conflicts.  GUS users may get no sound at all under Windows.

=> Q:  I HAVE A THRUSTMASTER WCS HOOKED UP WITH A JOYSTICK.  WHEN I USE THE STICK TO FLY, AND THE 'A' AND 'Z' KEYS TO MOVE FORWARD AND BACK, I START FLYING OUT OF CONTROL.  WHY?

Holding down keyboard keys will produce erratic results when the WCS or FLCS controls are installed.  See note in Section 4 for details.

=> Q:  WHY ISN'T MY MIDDLE MOUSE BUTTON WORKING IN DESCENT?

A:  	While Descent supports three-button mice, you still need to load a mouse driver that supports three buttons.  Typically Microsoft mouse drivers support two and Logitech drivers use three.

Modem/Serial Problems
----------------------------------
=> Q:  WHEN PLAYING A MODEM/SERIAL GAME, MY GAME FREEZES ON THE "WAITING FOR OPPONENT" SCREEN.  WHAT GIVES?

A:  	This screen will appear if you have died in/escaped from an exploding mine.  If the other player is still flying there can be up to a 60 second delay.  This is normal.  However, if your game sits at this screen much longer, chances are something is wrong.  Likely culprits:  opponent is having technical difficulties, interference with unshielded serial cables, loose cables, baud rate set too high, or uncorrected errors in the modem transmission.

=> Q:  MY MODEM GAMES ARE MUCH SLOWER THAN NORMAL ONE-PLAYER GAMES.

A:  	Try using a higher baud rate in the Com Settings menu.  If your computer does not have a 16550 UART, acquiring one will allow up to 38400 baud when communicating with the modem.  See the Modem/Serial Game section for details. 

=> Q:  STRANGE THINGS HAPPEN IN MY MODEM/NULL-MODEM GAMES.  WHAT CAN I DO TO HELP THIS?

A:  	This may be a result of dropped serial characters.  Some examples of "strange" things:  players not dropping powerups when killed, ships jumping from place to place on screen, or ships flying through doors that appear closed.  If you get error messages during play or during the "waiting for opponent" screen, this could be the cause as well.

These problems may occur for several reasons.  Serial play adds an additional burden to the CPU when playing the game, so a computer capable of playing the game in single-player mode may have difficulties with modem or serial play.  If you are using a 4-megabyte machine, the disk activity needed to run the program in a small memory space can cause lost characters.  A lot of sound activity can also cause lost serial characters.  Increasing the RAM for the game or reducing the number of sound channels in the detail settings menu can sometimes help.  Of course you can also reduce the baud rate in the Com Settings menu to slow down the game somewhat while improving reliability.

The best thing you can do to improve serial performance is to equip your machine with a 16550 UART.  However, even with this UART 38.4k baud rate can still be problematic if you have the burden of low RAM or heavy sound activity, so don't be ashamed to run a 16550 UART at 19.2k baud if need be.

Netgame Problems
----------------------------
=> Q:  I'M GETTING AN ERROR SAYING MY IPX DRIVERS AREN'T LOADED PROPERLY.  WHAT DO I DO?

A:  	First, make sure you have a reasonable amount of low memory available.  Although Descent uses a DOS extender to avoid low-memory hassles, some low memory is still needed for network buffers. If this fails, make sure your IPX.COM and other network drivers are loaded properly.  A good way to test this is to logon to a network server, if one is available.

=> Q:  MY NETGAMES SEEM SLOW AND UNRELIABLE.  WHAT'S UP WITH THAT?

A:  	Try using a different socket number.  It's possible that some other application on your computer uses socket 5100h and this is preventing Descent from opening a proper network connection.  Try large values for the -socket option (like 32 or 100).  Remember, your opponents will need to use the same socket you do.

=> Q:  DESCENT TELLS ME MY NETWORK CARD IS MISSING PACKETS.  WHAT THE HECK DOES THAT MEAN?

A:  	This can be a result of a slow network card, heavy traffic on the network, or software conflicts in your system.  If you get this message, you can rejoin the game and try again.  If the problem persists, one of the following could be to blame:

 - Loose cables.  Happens to the best of us.  Check the plugs on the back of your computer, specifically the ones running to/from your network card.

 - Too many players.  While 8 players is offered as the maximum in Descent, it's possible that your LAN or computer configuration can only support 4-6 players reliably.

 - Bad network card.  Some cards drop IPX packets even without heavy loads or interference.  If you suspect your LAN card, try swapping it with one from another computer.

 - Software conflicts.  Other drivers may be running that cause problems with the network interrupts.  These conflicts may not emerge when performing other LAN tasks that either don't use IPX or have layers of error-checking.  Try removing unneeded drivers from your CONFIG.SYS and AUTOEXEC.BAT.

 - Router problems.  Playing Descent with players on different sides of a router may cause lost packets or delays.  Playing this way is not recommended because it creates a significant load on the router that may disturb other LAN users.
