Demos

Half-Life: Uplink

The official public demo for the game, it includes an exclusive chapter (and a training level) with content not found in the full release.

It can be downloaded here.

Note that the demo uses an older version of GoldSrc and may have compatibility issues with modern systems. For full compatibility, the SteamLink mod reworks the demo as a Half-Life mod.

Half-Life: Day One

A pre-release demo exclusive to OEMs, it contains the chapters from the full release up to and including "We've Got Hostiles" (5 chapters and a training level).

It can be downloaded here.

Note that the demo uses an older version of GoldSrc and may have compatibility issues with modern systems.

Version differences

Half-Life: Dreamcast

A mod that ports the Dreamcast version as a Half-Life mod is available on Mod DB.

Essential improvements

Skip intro videos

-nointro[citation needed]
Use the -nointro command line argument.

Higher definition models

The High Definition Pack was created by Gearbox and first released alongside with Blue Shift on June 12, 2001. It was released for free on Steam on August 30, 2005, with a fixed version released a year later. This pack replaces most weapon and player/enemy models with higher polygon versions, substantially altering the style of some of them in the process.

For other options follow this guide.

Remaded Old Main Menu

This mod nearly brings back the old main menu before it was changed after when the game got a Steam release. Besides the additional main menu soundtrack, it allows you to select any mods for the game and launch it without even restarting Steam. It can be downloaded from this page.

Xash3D

Xash3D is a custom GoldSrc build made from scratch which aims to overcome the limit of the GoldSrc engine and even fix compatibility issues that are present while playing on modern systems. It also brings back most of the features which got removed from the recent update for Half Life through alternative means such as using OpenAL Soft for the 3D sound.

Enabling developer mode

Enabling developer mode will allow use of in-game cheats and various console commands.

Turn on the developer console[citation needed]
Use the -dev command line argument. Notes The developer console can be opened by pressing ~ (Note you may have to turn it on in the in-game settings). You can use the console command sv_cheats 1 to allow the usage of console commands such as god and noclip. Note that you might have to reload a save-game after enabling cheat-mode for certain commands to work.

Video settings

In-game video settings (Steam version)

Template:Video settings For a list of console commands:

OpenGL texture filtering

Disable OpenGL texture filtering
By default the filtering is enabled (not in Software rendering mode). Go to <path-to-game>. Create a file called autoexec.cfg. Add new line gl_texturemode gl_nearest. Save the file.

Overbright lighting

The retail version supports this feature for improved dynamic range of lighting. It is arguably the correct way of displaying the game, as it matches the brightness of the software renderer. Two different intensities (gl_overbright 1, gl_overbright 2) are available. However, getting it to work in the OpenGL renderer can be problematic, as it seems to conflict with multitexturing on most graphics cards. Also, with one of the later patches the settings "1" and "2" yield the same result.
It is easier to get working in Direct3D, though that renderer has its own set of problems. In the Steam version, the feature has been completely regressed since the removal of the Direct3D renderer.

Issues in Direct3D

On certain graphics cards, using the D3D renderer can result in severe input lag, even with disabled VSync. The fix for this is to set gl_d3dflip 1. Other typical issues include missing decals (fixable with gl_polyoffset -0.01) and Z-fighting (may vary depending on graphics hardware, check driver Z-buffer settings if applicable).

Color depth in the retail version

The retail version defaults to 16-bit color depth, presumably to save on performance on contemporary graphics hardware. This can be resolved by running the game with -32bpp argument.

Set HL.exe to high priority[citation needed]
Open Half-Life. Press Ctrl+Esc+⇧ Shift in order to open the Task Manager. Under the Processes tab, find HL.exe and right click it. Set its priority to high.

Missing Voice and Multiplayer Tabs under Options
