Diffusion is a Half-Life mod in its own universe, powered by Xash engine.

Posted by on

Hello guys.

Diffusion is the mod for Half-Life I've been working on since around 2013 but decided to post it here, so it would maybe speed up the process since I'm kinda lazy sometimes. I changed the story lots of times and it still has holes but at this point it can be published, I think. The original name of the mod was Black Mesa: Extreme Condition and it was the second part of my S.W.A.T. mod (my very first newbie work) and had different story etc.
My original plans were to make a successor of my bad mod. I always wanted to create one but in that time I really didn't understand what I'm doing. By now Diffusion grew a lot so I had to move to Xash engine because of the map sizes and engine's advantages.

About the original content:
Unfortunately, I'm only a mapper and always have been, so I have no idea how to make models other than simple cubes and I can't make textures since I'm bad at photoshopping. I use textures and models I can find in the internet which are in free access, any useful content (models/textures/sounds) which was recompiled from various games/mods for HL1 formats. I mostly use HL2 and HL1 textures together with some free textures I found on the internet. I'm not going to claim any rights for all used models/textures and the mod will be obviously free.

In the mod I use most of Half-Life NPCs - the majority of them will be retextured soldiers and aliens.

Other than that, what I did/do/will do entirely by myself are:
• Story/universe
• Level-design
• Soundtrack
• Voice acting


• If you find your model/texture in my mod and want it to be removed or want to be credited - I'm always up for it. I respect everyone's work but I can't track everyone down for every texture and model used. I hope you can forgive me about this.
• I'm NOT going to sell this in any possible way, this mod is non-commercial and will be available strictly for free download.
• I'm NOT going to claim any custom models/sounds/textures used as mine unless I made them by myself from scratch.


Server room (Ch. 2)

What's done and what's planned?
At the moment of writing this there's almost 30 maps (5 chapters). The 1st chapter will be remade from scratch as it's not matching my today's standards and there were slight changes in the story (those maps are 7 years old). The rest of the maps are in the state of missing enemies/scripts/dialogues/some minor brushwork.
Planned to be made:
1) voice acting and dialogues (no matter how the quality is going to be there, I never really tried, but dialogues is the only choice to deliver the story. I tried with the text, but believe me - it didn't go well).
2) original soundtrack (I'm mainly a musician/sound engineer, you can check my works here - Soundcloud)
3) mapping-mapping-mapping.

Back in 2013 I planned a simple Half-Life mod with a few maps…now it went a bit too far, but I wish to keep it simple. I'm not going to make a revolution in story-telling or hollywood action scenes. I just do it as a hobby in a free time.


Red dimension labs (Ch. 3)

The story.
The story sets in its own universe and not a part of HL universe in any way.
The story goes around James Smith, who's been serving in SWAT (yeah, a way to say "hi" to my old mod) and now on vacation, going through Utah, USA, by car on some deserted road. His car brakes down, and he finds a place nearby which is not some abandoned-looking factory, as seem at first sight, but a scientific lab which runs various experiments related to physics/chemistry and interdimensional teleportation. As he sees, how soldiers broke through the lab, he decides to follow them and investigate the matter. He finds dead scientists and very curious about this place, why it's under attack by government (regular army guys) and why they kill unarmed people. He will find a female ally scientist (Alice) who will tell him everything and they going to stand up against this, save everyone and everything they can. But that's just a start…
The other notable characters are Andrew and Mike, who are the owners of this scientific corporation. You will discover what happened to Mike as he seem to be absent, and what the real plans of Andrew are.

I'm going to try to deliver the story with dialogues as far as I can, but I will probably include a file explaining the whole universe in the release (which not going to happen this year, not the next year…).
But I promise I will finish it.
