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.

Hi, I found this mod to be extremely great in graphics. But I have 2 questions.
1: Where can I find the opengl32.dll at? It doesnt appear in my folders anywhere.
and 2: Could it be possible to enlarge the warning about the modified opengl32.dll? Some people might miss it.
Thanks in advance

I've played it, and I didn't like it. Okay, graphics are nice, but the gameplay was simply a mess. There were some places wich seemed accessible, while in fact they were clipped down, wich made it both confusing and frustrating, as it took away from the game. There weren't enough medkits around, neither weapons. I can't count how many times I had died or cursed because I was just about to die. The game is unnecessarily difficult, there's not enough items anywhere. If this were some small tech demo with lots of fancy showcases, I'd be happy, but this is a minimod, and at being a minimod it fails, badly.
The end garg fight was simply out of the line. By the time I got there I had low hp and little armor, I did not even bother trying to cheat, the game was completely boring as far as gameplay went.
I also saw many graphics bugs, such as weird bugs on the shadows, incorrect depth order on sprites and some weird texture shifting on certain textures.
Overall it was frustrating. Also it tries hard to be a Deus Ex with it's passwords and documents, especially since it took models right out of Deus Ex, couldn't you have made your own? Half-Life models, or models from other HL mods? Okay, but a completely seperate franchise? It's like as if I took models out of Crysis and put them in Half-Life. It'd look dumb and would destroy the illusion, just like those Deus Ex models did.
So, bad item placement, glitchy physics, bad enemy placement, boring gameplay, and content stolen from another game. The only good side is the graphics, wich themselves are buggy and comparatively slow on my computer, wich can handle F.E.A.R. on maximum settings perfectly.

Sorry, but this blows. I give it a 4/10
Next time, if you want to make a tech demo, make a tech demo. It's clear that this was a tech demo, but since you made a minimod out of it, I had reviewed it as a minimod, not a tech demo.

Well it is a review, you see that correctly. I've tested it myself, and I gave my own opinion here. Please, tell me exactly why you believe that my review isn't what you'd imagine, and don't just tell me what rating you'd give the mod. You're not explaining your point of view.

This is NOT a tech demo. For tech demo, see "HLFX:Single Demo" nearby. This is a simple classic mod with several new features and outstanding, uh, well, "a bit improved", graphics. :)
As for the difficulty, the game is way too easy for me at any skill level, and I couldn't even imagine it may be difficult for someone. And this does not depend on skill.cfg at all - it probably depends on gameplay tactics or something.

Well, it's easy for you. Maybe you guys should have playtested it with more people, because I'm a HL veteran, and while I can play through most mods unscratched, this was a major pain. I see where you're trying to go, but I can assure you, it's not my gaming skill that's bad. Maybe you guys should playtest properly next time.
I agree that the graphics are extraordirnary for Half-Life, but as I said, there's room for improvement. You also seem to completely ignore my other points, wich I consider to be crucial in why this "mod" is flawed.

Well, I have nothing to say for other points. Graphic bugs? Yes, there is a lot of them and this hardly depends on graphic card and drivers. I've been developing graphic improvements for HL for years and now I'm just tired of fighting with such things as engine restrictions and crappy OpenGL drivers, and I left off HL and switched to my own engine a year and a half ago (yes, this graphics was actually complete in 2008). And now I release my work so you can see what I did and what I did not. You may like it or you may not but it's the final version, apparently the most stable and bug-free.
Stolen content? I am not a modeller, so I prefer to take model from a commercial game rather than to take model from other non-commercial mod, or to ask smb to make it and wait for centuries.
Bad item & enemy placement? Well, my betatesters reported it's okay. Everybody can't be pleased, actually.
As for playtesting I agree with you. If there is a miracle and we complete the developement of HLFX:Single, we will playtest is more thoroughly.

The problem is that I think you only betatested it with team members. You need to grab some random faces out of the community, otherwise you can't adjust to the general gamers. I also understand that you are short on resources, such as a full team, but the way you solved it is possibly the worst. I love Deus Ex, and it felt weird and out-of-place to see them in Half-Life, if you get what I mean.
Playtesting is important, because it would have shed some light for you on why item and enemy placement wasn't the best. It was easy for you and your team members because you knew what was coming, all the time.
