A singleplayer mod for Half-Life based on a new version of Half-Life FX engine. While the main mod, HLFX:Single, that uses maximum of engine features, is still being developed, you can have an opinion of relatively small project entitled HLFX: Lost in Black Mesa.


Many people were missing during the Black Mesa incident. Only a few, a mere handful of people succeeded to reach the surface, where they were being awaited by armed troops of marines with an order to annihilate any witness of the catastrophe. You are Alex Jones, a young scientist that by a lucky chance worked in an HEV suit when it was an accident. When leaving your laboratory and entering an elevator you could not even imagine that the way out will be so long and difficult. Kindred and friends have already considered you a missing person. But can it be true that a person lost in a huge underground complex will meet them again and tell the truth about what was happened in the Black Mesa Research Facility?


The mod uses a lot of daring innovations brought by a latest version of Half-Life FX:

  • Static diffuse and specular bump-mapping
  • Dynamic bumpmapping for a flashlight
  • Parallax mapping
  • Shader script system
  • Refractive glass
  • Projective soft shadows
  • Projective flashlight
  • High-resolution textures and decals
  • Anisotropic texture filtering
  • Detail textures
  • Light bloom effect
  • Heat haze effect
  • Particle systems
  • Interactive physics elements


HLFX: Lost in Black Mesa consists of three gameplay levels. You will visit a laboratory complex and a part of Black Mesa monorail transit system. Like a HLFX:Single demo version, you will meet doors with keypads and will have an opportunity to manually delve into electric wiring to restore the power for some systems. Do not forget that Black Mesa complex is way too large, so there are some secret places in the game that are not accessed easily. Upon revealing a secret the game will show how much places like that there are on the level. And they are on each level, so keep your eyes open! In other respects this is a classic Half-Life-style gameplay - we still do our best to keep the original atmosphere. And you will judge whether we made it.


Please launch the mod only with the supplied launcher lbm_fx.exe located in the "lbm_fx/system" directory! Otherwise game may not work. If you need to run the game with additional peremeters, add them to the shortcut for that laucher. Please note that the game uses a modified opengl32.dll that is copied into Half-Life directory on game startup. When game shuts down this file is left in the game directory. In this case some anti-cheats may consider you a cheater and ban your CD-key. Therefore either disable anti-cheating software or manually delete opengl32.dll from Half-Life directory before running multiplayer games or mods. Chain Studios has no responsibility for a probable ban and frankly warns you.

I totally agree with Xenomorph; This mod is very impressive.

Honestly, it gave me back the feeling I had when first playing Half-life ages ago. The new stunning graphics are playable with high framerates making it a very immersive and an enjoyable experience.

The new ideas integrated in this mod such as the keypad, infos you can read or the restoration of power with a minigame make this a surprising piece of work.

Nice job bringing that good old game from 1998 back to life! Looking forward to further releases!

Thanks for the tip :) The only thing i cant get work is the english patch. I installed it in the "lbm_fx" folder, but still no English texts in the game.

You should install it into "Half-Life" folder, not "lbm_fx". Otherwise you will find new "lbm_fx" folder in "lbm_fx" main folder. Just cut-n-paste files from it to upper level.

Ok i just installed this mod and have to say - WOW
I cant believe that the old Half Life engine can deliver such beautiful effects...it is just mind blowing and i still cant believe what im seeing. I installed the game under STEAM and it seems to be no problem for me to start the game under STEAM and play it. I still get a warning when i start it under STEAM that i should start the game by using the lbm_fx.exe in the system folder, but i dont understand what the window is saying when i start lbm_fx.exe cause i think its in russian. At this point there seems no problem playing it with STEAM because all the new graphic effects are noticeable so i will use that instead of the lbm_fx.exe.

You can ignore that message and start the game anyway if you have a quite modern video card. For, e.g. GeForce FX, this may result in some rendering problems. But lmb_fx.exe works only on a WON version.
If you don't use lbm_fx.exe, you may also edit system/gfx.cfg to adjust graphics quality. The default is "Ultra High" except two effects:

r_pp_fsaa "0"
r_pp_bloom "0"

You may change them to

r_pp_fsaa "1"
r_pp_bloom "2"

to get the best quality (and least performance however)

Обалдеть. HLFX всё круче и круче. Освещение суперское. Хочу такую графику в оригинальную HL. Регдолл тоже порадовал. Подглючивающий, но тем не менее реальный и не зависящий от модельки. Шик! Всё остальное тоже выглядит обалденно. 10/10

Again, I reuploaded the install files. There was a serious problem with readme information - it was incorrect that game deletes opengl32.dll on exit. It does not. Please remove it manually before playing any multiplayer game with anti-cheating software!
Also there are small bug fixes and several new textures.
