II. HALF-LIFE OPPOSING FORCE GAME INFORMATION
=======================

Addendum to Manual:

The medic class can heal other nearby friendly soldiers. If a friendly soldier is wounded and calls "Medic!" within earshot of the medic, he will move to their aid.

However, players often will wish to keep all of the medic's supplies for themselves or the player will simply not want the medic to interrupt his alert combat mode by healing a wounded soldier. Therefore, a medic that has been commanded to follow the player will never aid another wounded soldier. To coax your medic into healing other soldiers, lead him to the wounded characters and "use" him to tell him to stay put. When nearby soldiers call for him, he'll heal them with any remaining supplies he has. The medic will only heal other soldiers who call for him when he is not following the player.


Note: No aliens were harmed during the creation of this game.

Also Note: Sean Reardon still just thinks it's all about him.

[NOTE] CD audio playback was left enabled for this demo. The music you will hear while playing Half-Life: Opposing Force is the music from the original
Half-Life (since you will probably have the Half-Life CD in your CD-ROM drive to start the game). All new music was recorded for
Half-Life: Opposing Force and is included on the CD with the retail version of the add-on.

III. GENERAL TECHNICAL ISSUES
=======================

A. DRIVER ISSUES
The copy protection used on this disc is potentially incompatible with the following CD drives:

Sanyo CRD-256P
Sony CDU77E
Acer CD-624a
MATSHITA UJDB110
Various Pioneer DVD models
All Yamaha CD-R's
Pioneer DR-A01S
Pioneer DR-A24X
Samsung SCR-1231

When running Half-Life in OpenGL, you must select '3Dfx Mini Driver' from the drivers list in the Video Options menu if you have a 3Dfx card (Voodoo, Voodoo2, Rush or Banshee). Choosing the 'Default' driver may severely impact Half-Life's performance.

The Diamond Viper 550 drivers older than 4/2/99 cause the game menus to be drawn incorrectly. Use the drivers from the Nvidia home page (http://www.nvidia.com) dated 2/17/99 or later.

Make sure the most current version of DirectX is installed on your computer. DirectX 6 is the most current version (as of 10/31/98), and it is included on the Half-Life CD in the 'DirectX' folder.

If you are running a pre-OSR2 release of Windows95, get the OpenGL 1.1 fix in order to run Half-Life in OpenGL mode. The fix can be found at ftp://ftp.microsoft.com/softlib/mslfiles/opengl95.exe

Make sure you have installed the most recent drivers for all your hardware before playing Half-Life.

B. SOUND PROBLEMS
If you don't hear any sounds while playing Opposing Force or if you only hear music, another application you are running may have control of the sound hardware. Exit Opposing Force, close the other application, and restart the game.

A3D 1.0 versus 2.0
Half-Life: Opposing Force requires version 2.0 of A3D. You can upgrade your A3D from 1.0 to 2.0 by downloading the latest drivers from Aureal's website at www.a3d.com. If you try to enable A3D support in Opposing Force without upgrading to 2.0, you will get an error message when starting the game.


CAN'T HEAR CD MUSIC
If you don't hear any music while playing Opposing Force, the problem is likely to have one of three causes:

1) The Opposing Force CD needs to be in the first CD-ROM drive (only an issue if you have more than one CD-ROM drive).
2) Another application is actively using the CD Audio when Opposing Force starts up.
3) CD Audio isn't enabled for the CD-ROM drive.

To fix the first problem, make sure the Opposing Force CD is in your first CD-ROM drive. To fix the second, close other applications which may be accessing your CD-ROM drive, such as CD music players. If you still can't hear the Opposing Force music, run the application "CD Player" that comes standard with Windows located on your Start Menu Programs, Accessories, Multimedia. If the CD Player doesn't play the music tracks on the Opposing Force CD, then check Control Panel, Multimedia, CD Music, CD ROM Selection, and make sure it's set to your first CD-ROM drive. If you're under NT, you may also want to check Control Panel, Devices, Cdaudio, and make sure it's not disabled. Once the first two requirements are met, and the "CD Player" application works, then Half-Life should be able to play the CD music without any problems.


CD MUSIC VOLUME
You cannot control the CD music volume within Opposing Force. To adjust your CD music volume, go to the Windows Start Menu, Programs, Accessories, Multimedia, and select the Volume Control applet.


CD AUDIO SLOWDOWNS
Some CD-ROM drives take a few seconds to spin up to their playing speed. You may notice some parts of the game that will momentarily slow down before the CD audio will play.

SOUND QUALITY PROBLEMS
If your sound is skipping or cracking, you may need to adjust your direct sound configuration in Opposing Force. There are two common adjustments you can make:

1) Adjust _snd_mixahead. If you have access to the Opposing Force console, type "_snd_mixahead 0.2" at the console. If not, create a file with notepad that contains the line:
_snd_mixahead 0.2
And save it in your Half-Life\Valve\ directory. Name the file "autoexec.cfg".

2) Disable direct sound. Run Opposing Force with the command line argument "-wavonly". Edit the Opposing Force shortcut. The 'target' field should say: "HL.EXE -game gearbox -wavonly".

D. 3D HARDWARE ISSUES
Half-Life has the ability to use both OpenGL and Direct3D. Many cards with support for 3D acceleration will provide both OpenGL and Direct3D drivers. Which one is better depends upon the quality and performance of the drivers themselves, and will vary from card to card.

The latest release of DirectX, version 6.0, is included on the Half-Life CD. It should be automatically installed as part of the Half-Life installation process. If you need to reinstall at a later time, open the DirectX folder on your Half-Life installation CD and run dxsetup.exe.

In general, make sure you have the latest versions of the device drivers for your display hardware. Most graphics card vendors make them freely available on the Internet, and a collection of links to sites of many popular cards is installed on your hard drive along with Half-Life. The default location for this file is:

C:\SIERRA\Half-Life\media\DrvPage\default.htm

Video configuration is set in the Configuration\Video\Video modes menu in Half-Life.

The following section explains the known driver and compatibility issues for specific chipsets at the time of Half-Life's shipping. If you have any questions about which chipset is incorporated in your graphics card, consult the documentation that accompanied your card, or contact the card manufacturer.

3DFX Banshee, Voodoo 1, Voodoo 2, Voodoo 2 SLI

Get the latest drivers from your card manufacturer or get the latest drivers directly from the 3DFX site. Half-Life ships with the current, tested GL mini-driver. Make sure that you have Glide version 2.54 or above. Half-Life does not support Direct3D on Voodoo cards.

The Voodoo 2 running in SLI mode on Windows/NT is prone to crashing. The solution to this instability is to either get an updated driver from 3DFX, disable SLI mode, or run under Windows 95/98.

3DFX Rush

With the current drivers, Half-Life supports the Voodoo rush in software mode only. Check with 3DFX for an updated driver that offers support for Half-Life

NVIDIA Riva 128

You must have Windows 95 OSR 2 or later, Windows 98 or Windows NT. As of shipping, Half-Life Riva 128 OpenGL support requires the latest reference driver from NVIDIA. Get this driver off of their site, www.nvidia.com. Direct3D support is currently unavailable. Contact NVIDIA for a Direct3D driver that supports Half-Life.

NVIDIA TNT

Half-Life supports the TNT in software, OpenGL and Direct3D modes. Get the latest driver off of NVIDIA's site.

If you run OpenGL on the nVidia Riva TNT and switch to Direct3D, decals may not appear. To fix this, type gl_polyoffset 4 at the console.

Matrox G200

Half-Life supports the G200 in software and Direct3D. Get the latest driver from Matrox's site, www.matrox.com. Matrox will also be providing a GL mini-driver that will support OpenGL in Half-Life. Check with Matrox for details.

S3 Virge

Half-Life supports the Virge in software mode only.

S3 Savage

Half-Life support the Savage in software and Direct3D. You can get the latest drivers from S3's site, www.s3.com. S3 will also be providing a GL driver that will support Half-Life. Check with S3 for details.

General Issues:

Missing Decals (i.e. Bullet holes)
Half-Life uses a feature of OpenGL and Direct3D that some video card drivers do not support correctly. To over ride the default settings for this feature, put this line in your opengl.cfg or d3d.cfg file:

gl_polyoffset 0.1

If this doesn't work, try -0.1, 1 or 20. This tells the driver how far to offset the decal from the surface of the polygon that the decal is being applied to.

Direct3D or OpenGL are running very slow
On some cards that don't fully support Direct3D or OpenGL, Half-Life will fall back to a software emulation mode. These modes are very slow. If your Direct3D support is slow, try selecting OpenGL, and vice versa. If neither work, change your settings to use Half-Life's software video modes instead and the speed will improve.

Direct3D Input seems lagged.
If your input seems to lag behind the visual display on occasion, add this line to your d3d.cfg file:

gl_d3dflip 1

Parts of the screen are flashing (in Direct3D or OpenGL)
Some older, non-3DFX cards have a problem with clearing the z buffer and this can cause parts of the screen to flash. If you are seeing this, put this line in your opengl.cfg or d3d.cfg file:

gl_ztrick 0

Network instability
If you have a connection to the Internet that is unstable, or prone to packet loss, try typing 'cl_nodelta 1' at the console (bring down the console with the ~ key). This will improve your overall network stability, but will sacrifice your overall latency.

COMMON QUESTIONS
What can I do if the game is too dark?.
Some monitors are darker than others, but Half-Life provides controls to correct this problem. You will need to adjust the Gamma and Glare Reduction settings in the Configuration\Video\Video options menu in Half-Life. These are used to adjust for different kinds of monitors and room brightness. Adjust the two sliders so that the Soldiers camouflage pattern is dark but visible. If this still doesn't work, you then may need to adjust the actual brightness and contrast of your monitor. This is usually done by adjusting buttons or knobs on the front of your monitor, but all monitors are a bit different so you may want to look through your monitors documentation to be sure. Some places in the game are intentionally dark, and you'll need to use your flashlight, but you should be able to see everything without difficulty in the opening train ride and throughout the first part of the game. Some graphics cards also have support for controlling how bright the display is. If your card's device driver supports this, you can find it by going to the Windows control panel, and selecting the Display applet.

What can I do if the game looks washed out?
The most likely cause is that your monitor is slightly brighter than average and the default game settings are for a darker monitor. You will need to adjust the Gamma and Glare Reduction settings in the Configuration\Video\Video options menu in Half-Life. These are used to adjust for different kinds of monitors and room brightness. Adjust the two sliders so that the Soldiers camouflage pattern is dark but visible. If this still doesn't work, you then may need to adjust the actual brightness and contrast of your monitor. This is usually done by adjusting buttons or knobs on the front of your monitor, but all monitors are a bit different so you may want to look through your monitors documentation to be sure. The most common problem, especially on new computers, is that "black" isn't showing up as black, but more of a dark gray. Turn the Contrast down until the border around the edges of the picture are totally black, then slowly turn it back up until it just before it starts getting visibly lighter. You may need to adjust your monitors Brightness back up after you do this. . Some graphics cards also have support for controlling how bright the display is. If your card's device driver supports this, you can find it by going to the Windows control panel, and selecting the Display applet.
