Warnings

The macOS (OS X) version of this game does not work on macOS Catalina (version 10.15) or later due to the removal of support for 32-bit-only apps.

Half-Life is a singleplayer and multiplayer first-person action, FPS and shooter game in the Half-Life series.

The retail release was published by Sierra Entertainment up until the publisher lost all publishing rights to Valve's titles in 2005. The macOS X and Linux versions were released in 2013. On November 17, 2023, to celebrate the game's 25th anniversary, an update was released which added new and previously exclusive content, as well as improving Steam Deck support. The update initially broke compatibility with many mods (including other GoldSrc-based Valve games), but mod compatibility was fixed in the days following the release of the update.

Like most of Valve's library, the game still receives bug fixes and general maintenance updates. It also enjoys a large community base, and various mods are released regularly.

Demos

Half-Life: Day One

A pre-release demo exclusive to OEMs. It contains the first five chapters from the full release and the training level. It can be downloaded here.
Note that the demo uses an older version of GoldSrc, which may have compatibility issues with modern systems.

Version differences

Half-Life: Game of the Year Edition comes with both the base game and Team Fortress Classic.
Half-Life: Dreamcast is an unreleased port of Half-Life to the Sega Dreamcast. It includes various differences from the PC release (ex. modified levels, new models, adjusted difficulty, etc.). A mod that ports the Dreamcast version as a Half-Life mod is available on Mod DB.
The PlayStation 2 version has improved character models over the High Definition Pack (E.g. Eyeballs following movement, Reflections on metal helmets, animated fingers, Etc.), an Alien Mode cheat, more detailed and animated models for health & HEV chargers & retinal scanners, an extended Hazard Course with an introduction, music added to the menu screen & the Decay expansion. None of which were officially put on the PC version. Although, a mod that ports the PS2 content to PC exists.
The version of the game before the 25th Anniversary Update is available as a beta in Steam titled steam_legacy - Pre-25th Anniversary Build. This version has the best mod compatibility since the 25th anniversary made big changes that some mods may not be compatible with.[4]

Essential improvements

Official retail patches

These are not needed for the Steam version as that already contains the latest version. The Steam version is even more up to date than the Retail version.

4K Ultra HD

Assets for retail and pre-25th Anniversary Update versions are designed for 640x480, and UI may be too small at higher resolutions.
25th Anniversary Update updates the GUI to adaptively scale from 480p (640x480) to 4K resolutions.
Increase font sizes[7][8]
  1. Open <path-to-game>\platform\resource\TrackerScheme.res in a text editor.
  2. Under "Legacy_CreditsFont", change "tall" as desired to change the size of the in-game credits font, used for the opening credits, level titles, and tutorial prompts.
    Recommended settings for a similar font size to that used in 640x480 are:
    • "30" for 720p or 768p
    • "40" for 960p, 1024p, or 1080p
    • "50" for 1200p
    • "60" for 1440p
    • "70" for 1600p
    • "80" for 2160p ("4K")
    • "120" for 2880p ("5K")
    • "135" for 3240p ("6K")
    • "180" for 4320p ("8K")
  3. Save the file.

Field of view (FOV)

FOV adjustment may be necessary at widescreen resolutions on non-25th Anniversary Update versions.
Field of view[9]
  1. In the game's launch options, add +default_fov ###, replacing ### with the desired FOV.
  2. While in game, open the console (~).
  3. Type default_fov and press Enter to confirm the changes have taken place in-game.

Notes

Weapon models are affected by changes in FOV.
To maintain identical vertical FOV to the 4:3 FOV at 16:9 resolutions, use 106. At 21:9 resolutions, use 121.

High frame rate

Use +developer 1 +fps_override 1 +fps_max ###[10]
Disabling the cap may reduce the speed at which the player moves objects.[10] NPC turn rate bug was fixed.[11]
Disabling the cap will cause the train at the beginning of the game to get stuck easily , the elevators take life away from the character and that the sample in the antimatter spectrometer cannot move [12]

OpenGL texture filtering (Retail/pre-25th Anniversary Update)

By default the filtering is enabled (except in Software rendering mode).
Skyboxes are always bilinear filtered, regardless of texture filtering settings.[13]
Disable OpenGL texture filtering[14]
  1. Go to <path-to-game>.
  2. Create a file called autoexec.cfg.
  3. Add new line gl_texturemode gl_nearest.
  4. Save the file.

Notes

Using the line gl_texturemode gl_nearest_mipmap_linear instead will enable mipmapping to prevent some textures from flickering at a distance, but will be blurry if not combined with anisotropic filtering.

OpenGL overbright lighting (Retail/pre-25th Anniversary Update)

Overbright lighting increases the rendering dynamic range, resulting brighter and more colorful visuals. This also fixes chromatic aberration on brightly lit lightmaps.[15]
The 25th Anniversary Update fixed the overbright lighting and deprecates gl_overbright in favor of gl_use_shaders.[16]
Overbright lighting normally only works on the Direct3D and software renderers.[17][18]
Nvidia GPUs: Enable the GL extension limiter[19]
  1. Download and run Nvidia Profile Inspector.
  2. On the Half Life profile, set Extension limit to On. Apply changes.
  3. Go to <path-to-game>.
  4. Create a file called autoexec.cfg.
  5. Add new line gl_overbright "1".
  6. Save the file.

Notes

Doing this disables ALL OpenGL extensions, not just the offending extension! This has side effects:
  • Disables non-power of two texture support; some textures will have uneven rows of pixels.[20]
  • Disables multitexturing, which is used for detail textures, which may effect the appearance of other games and mods that share hl.exe, including Counter-Strike: Condition Zero and Day of Defeat.
Doing this disables the Steam version's built-in MSAA. On the Half Life profile, change Antialiasing - Mode to Override any application setting and Antialiasing - Setting to the desired level of antialiasing (such as 4x [4x Multisampling] for a vanilla look, or 32xS [Combined: 2x2 SS + 8x MS] for maximum antialiasing).
Intel/AMD GPUs: Use this GLIntercept config[21]

Notes

As this method uses a custom OpenGL32.dll, it should not be used in VAC-protected servers.
Doing this also fixes performance issues with dynamic lights on Intel graphics.
Use this Python script[22]

Notes

As this method modifies hw.dll, it should not be used in VAC-protected servers.
Does not disable OpenGL extensions.
Mesa drivers on Linux: Disable GL_ARB_multitexture extension with environment variable[23]
  1. Right click on Half-Life in the Steam library and choose Properties.
  2. Go to General tab and add MESA_EXTENSION_OVERRIDE=-GL_ARB_multitexture %command% to launch options.

Notes

For retail and older versions running through Wine, simply add this environment variable right before Wine command.
For example: MESA_EXTENSION_OVERRIDE=-GL_ARB_multitexture wine hl.exe +gl_overbright 1.
Proprietary Nvidia drivers on Linux: On the retail version, write __GLX_VENDOR_LIBRARY_NAME=mesa before everything else[24]
  1. Open terminal and go to the Half-Life directory.
  2. Launch Half-Life using this command: __GLX_VENDOR_LIBRARY_NAME=mesa MESA_EXTENSION_OVERRIDE=-GL_ARB_multitexture wine hl.exe +gl_overbright 1 -console.

Notes

Mesa drivers might need to be installed first for this to work.
This method cannot be used to play Half-Life on the Steam version. The game refuses to work otherwise.
Other drivers on Linux: Use Zink and disable GL_ARB_multitexture extension[25]
  1. Right click on Half-Life in the Steam library and choose Properties.
  2. Go to General tab and add __GLX_VENDOR_LIBRARY_NAME=mesa MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink MESA_EXTENSION_OVERRIDE=-GL_ARB_multitexture %command% to the launch options.

Notes

Requires a GPU that supports Vulkan.
Driver-independent, can be used on any Vulkan driver.
Mesa 23.2 or higher is recommended for best performance.
__GLX_VENDOR_LIBRARY_NAME=mesa is only necessary on proprietary Nvidia drivers.
Use HLFixes[26]

Notes

Fixes other bugs like music stopping during level transitions.

Issues fixed

InstallShield progress bar hangs and does not load main setup window (Retail version)

The InstallShield used for the early releases can lock up waiting for a resource held by another process.
Find the offending process and terminate it[36]
Can be done using Resource Monitor (Vista or later) or manually terminating non-Microsoft processes one-by-one.
Core FTP server has been observed to cause this issue.

Run the game at screen refresh rate (Retail version)

The retail version of the game defaults to 60 Hz when running with Direct3D renderer in fullscreen mode.
Use the -freq <rate> command line argument[37]
Example: -freq 120 forces a 120 Hz refresh rate.

Input Lag in Direct3D (Retail version)

On certain graphics cards, using the D3D renderer can result in severe input lag, even with disabled VSync.
Set gl_d3dflip 1 in the console[38]

Missing Decals in Direct3D (Retail version)

Use gl_polyoffset -0.01 in the console[citation needed]

Logo Movies At Startup Play Inconsistently (Retail version)

Run with administrator privileges[39]
  1. Navigate to <path-to-game>.
  2. Right click on hl.exe and click Properties.
  3. Click on the compatibility tab.
  4. Check the box that says Run this program as an administrator.

No music playback (retail version)

Switch from CD playback to MP3[40]
  1. Put the MP3 soundtrack of Half-Life Steam version (see here) into <path-to-game>/valve/media/.
  2. Add ID3v1 tags to the MP3 files (see instruction here).

Notes

Make sure Half-Life is updated to v1.1.1.0 (see patch), adding MP3 playback support.
This requires a Steam account and Steam platform installed to access the content.
Burn the soundtrack on a separate CD
  1. Open the preferred CD burner utility program.
  2. Create a new audio project.
  3. Place a dummy file as track 1; since track 1 is data, the game skips it and moves straight to track 2.
  4. (This action requires a Steam account and Steam platform installed to access the content) Download the Half-Life soundtrack through Steam (see here) And begin placing the soundtrack from 01 to 27.
  5. Burn the CD.

Main menu issues (Retail Version)

In modern versions of windows the menu is usually not seen in full screen in addition to crashing when loading the game.
Run the game in compatibility mode for Windows XP (Service Pack 2)

Fatal Error - Available memory less than 15MB (Retail version)

Run the game in compatibility mode for Windows XP[citation needed]

Missing Blood & Gore (Steam version)

There is an issue with the current Steam release of Half-Life, it can end up downloading a few of the cut content from the German version regardless of the player's location.
Download this file to restore the lost gore[citation needed]

Black screen on startup (Steam version)

Disable FBO rendering[41]
  • Add -nofbo in the game's launch options.

Windows 7/Vista Performance Fix

In Windows 7 or Vista with modern hardware, some users may experience extremely low frame rates during gameplay.
Set HL.exe to high priority[citation needed]
  1. Open Half-Life.
  2. Press Ctrl+ Shift+Esc in order to open the Task Manager.
  3. Under the Processes tab, find HL.exe and right click it.
  4. Set its priority to high.

Missing Voice and Multiplayer Tabs under Options

Replace the liblist.gam file[42]
  1. Make sure Half-Life is not currently running.
  2. Download the replacement liblist.gam from here (download starts immediately).
  3. Extract into <path-to-game>/valve/, replacing the existing file when prompted.

Performance issues with dynamic lights on Intel graphics (OpenGL)

Dynamic light sources being present, such as the flashlight or flickering lights, causes significant frame rate drops and lag spikes on Intel graphics.
Use this GLIntercept config[43]

Notes

As this method uses a custom OpenGL32.dll, it should not be used in VAC-protected servers.
Doing this also fixes overbright lighting.

Mods

Xash3D

Xash3D FWGS is a custom open-source Half-Life-compatible engine, made to overcome the limit of the GoldSrc engine, fixing compatibility issues for the original non-Steam versions too[49]
It also includes quality of life options fit for modern systems, including HUD scaling.

Quality Of Life Fixes (Steam & Retail)

These fix certain small things without significantly altering the experience. Compiled from FWGS hlsdk-portable.
  • Fixes some viewmodel animations.
  • Fixes "rapid fire" crowbar when hitting certain corpses.
  • Fixes tripmine beam duplication.
Read the changelog on the GitHub page for more fixes.

Half-Life 1: Ray Traced

Half-Life 1: Ray Traced uses Xash3D: Ray Traced engine which is a variation of the Xash3D FWGS engine, with a custom path traced renderer.

MetaAudio

Alternative audio pipeline for GoldSrc. Re-implements 3D audio without replacing entire rendering pipeline. Combines A3D’s HRTF and Occlusion with EAX’s reverb.[50]
Not compatible with software renderer.[51]
Currently incompatible with the latest 25th Anniversary update[52]. A workaround for 25th anniversary update is to use MetaHookSv and load MetaAudio with it, see the instructions here.
Do not use on VAC secured server.

Higher definition models

Included in the Steam release. For the retail version of Half-Life and its expansions, the Official HD Pack can be found on PcGamingWiki.
The High Definition Pack replaces most weapon and player/enemy models with higher polygon versions that resemble the PS2 models. For other options follow this guide.
The option to enable the pack in-game is in the options menu, and the game must be restarted for it to take effect.
The effect changes the art style dramatically, and whether or not it's desirable is up to personal preference.

Full Audio Remaster

Makes all of the bit-crushed sounds & voices much more clear.
Requires Xash3D or MetaAudio.

Restored logo playback via ffplay (Steam & Retail)

This is an alternative way to get the logo movies playing like they should, but without using the engine itself. This uses a series of VBS, BAT, and PS1 scripts which will make the logos play with FFplay then launch the game. This allows higher quality videos to play and other formats that otherwise would not work in normal Gold Source.
Because this uses an external method not tied to the engine, works on all PC versions of Half-Life including the Pre-25th Anniversary version.

This will replace the existing Valve logo with a higher quality and newer version of the classic Valve logo (Open your eyes from 2004). Found within the files of the Source SDK Base 2013 Singleplayer. Available for Retail and latest Steam 25th Anniversary update.
Recommended to use with Sierra Studios splash mod.

Crosshair

See Half-Life Crosshair Changer to customize the crosshairs.
HD Half-Life Crosshairs
Upscales crosshairs to make them more visible when using Full HD or 4K resolutions.
Optionally changes color of the crosshairs for Blue Shift to better match add-on aesthetics.

WON styled menu text (25th anniversary update)

This modifies the main and pause menu text for Half-Life and expansions to look more like the WON version of the menus and fixes inconsistencies with Blue Shift's and Opposing Force's menus. This simply changes the text and does not change the menu colors, looks, or add/modify menu functions.

Enabling developer mode

Enabling developer mode will allow use of in-game cheats and various console commands.
Use the developer 1 in console[53]

Notes

The developer console can be opened by pressing ~. It may have to be turned on in the in-game settings first.
To allow console commands such as god and noclip, use the command sv_cheats 1.
A save-game might have to be reloaded after enabling cheat mode for certain commands to work.

Console commands

Games running on the GoldSrc engine can utilize these commands for various tasks.
Console is enabled by default in GoldSrc games, press ~ to open it.

  1. When running this game without elevated privileges (Run as administrator option), write operations against a location below %PROGRAMFILES%, %PROGRAMDATA%, or %WINDIR% might be redirected to %LOCALAPPDATA%\VirtualStore on Windows Vista and later (more details).
  2. SGSSAA is also technically possible, but a GPU driver bug results in affine textures becoming extremely blurry in OpenGL games such as this title, especially noticable when texture filtering is disabled.
  3. However, the default config provided by Valve heavily relies on Keyboard/Mouse bindings.

    This is prominent when texture filtering is disabled (as it should be). If texture filtering is enabled, this will result in textures with transparent sections having smaller transparent sections.

    Tested by disabling Steam Input completely and use DualShock 4, DualSense and Xbox Controllers on both Wired and Bluetooth. Seems to rely on SDL2 to handle overall Controller support.
