Half-Life Episode Two begins exactly where Half-Life ended, after accepting the job agreement with Gman, Gordon Freeman is sent back to the Black Mesa Research Facility, why? It's up to you to find out. Explore never seen before areas of Black mesa in seven chapters that will immerse you into a spooky and dark environment while you search for clues to reveal one of the darkest secrets of the facility and the reason why you were sent back in.

The Project:
Half-Life Episode Two is a horror/action single-player Half-Life 1 modification currently under development, the adventure features improved and redesigned game-play mechanics, lots of exploration and action, deep atmosphere well as a it's own unique plot set on the Half-Life Universe while partially staying true to the original Half-Life game-play.

With a restructured and improved game platform Half-Life Episode Two will feature lots of graphical improvements, extended game-play elements, a new sound platform, high quality level design, high quality models and compelling presentation.

The game will not, as of currently, support multi-play.

The Trinity rendering engine, or Raven as I used to call it before it had an official name, is now free for download with source code available, released under LGPL license you are allowed to do as you please with the code as long as credit to the original developer is kept, source code for Half-Life Episode Two however will remain indoors as of now.

Trinity Custom Edition

The Engine:
Half-Life Episode Two is powered by the Abyss engine, the successor of the Trinity rendering engine, which supports the following features:

  • Rewritten BSP renderer;
  • Rewritten Studio renderer;
  • Full multi-pass per-pixel dynamic lighting;
  • High resolution real-time shadow-maps;
  • A Particle engine;
  • High resolution textures;
  • Vertex buffer objects;
  • Advanced water shaders;
  • Detail textures;
  • High performance model manager;
  • Rewritten decal system;
  • Real-time mirrors.

The code-base is compiled in the latest C programming software and libraries using high level optimizations and support for advanced processor extensions. Vertex buffer objects are used to render world, models and particles, as a result performance is very fast.

Other advanced post process visual effects also include:

  • Aura glow-shells;
  • Motion blur;
  • Screen warmth glow;
  • Color effects;
  • Depth\Radial per-pixel fog;
  • Underwater caustics.

Due to high end requirements it is necessary that your system support at least OpenGL 2.0, as well as a fast enough processor with SSE support.

The game only supports the OpenGL renderer meaning that inferior video chip vendors might not correctly handle the game. Nvidia 5 FX series not supported.

This modification also uses the Amnesia Sound Engine, an open source sound platform, based on FMOD Ex library, available under LGPL license.

After a three month old update I finally found the appropriate moment to announce what has happened during the time nothing was posted on the profile.

I joined the army and by now, I almost finished recruitment, this of course means during that time I had little time to rest let alone work on hlep2, so that means development was stopped for the past 11 weeks, but I'm currently on vacation now and not only did I decide to tell you folks whats up but also to resume development, should be easier from now on and depending on my working schedule and activities I will try to give hlep2 some time whenever I can.

The rendering engine was also updated once more, and more updates are coming, not only is the engine incredibly fast but also looks nicer.

See ya around whenever I get a reasonable amount of new content developed, just enough to post another media update.

This mod uses too much of trinity features wisely and the mapping is too good. Even the developer, me myself got impressed by this mod's trinity usage.

Well thanks buddy, but I wouldn't call the level design "too good", I have seen better in this engine believe me ;).

Theres was also another mod that used it for a period called Half-Life Amnesia, but it is dead now too.

Abyss_048 uses it too:

Other mods that use it are Snow Facility:

HalfLife Episode Two uses it obviously, and another mod that used it was Raven City, which was the mod the engine was originally developed for which is now dead, but the engine continued development. All of these mods belong to people that keep close touch and are friends with Trinity's developer, hence the benefit of performing on it even before it was publicly released.

WoW, thanks dude! I am still too lack of idea to use trinity in my mod, all those mods you mentioned use trinity but have so so so much better performance than my mod. :(

But, still, your maps have same standard as the maps of those mods

You know what? That demo alpha installer STILL exists on my PC until NOW. I just can't delete that one.In fact, I finished it already 10 TIMES! Sometimes, I was close to deleting that, but whenever I remember you're gonna take a very long time releasing the full version of this mod, I kept that mod in my PC. That piece of file is AMAZING and I will hang on in it until you release yet another download. You believe it sucks, but to me, NO WAY! Sorry for this comment, I just can't imagine how good the beta and the final version will be.
This maybe my last comment until you update the MODDB site.

Very very cool mod. Can;t wait for release.
One question: are there any new gameplay features of the mod, or is it going to function alot like the first game? Will there be a limited inventory? Will you have to press the use key to pick up ammo? I'd love to know.

Your level design is extremely blocky, I feel as if your modified engine is going to waste because of this.

Man, some of your levels honestly lack detail, I think you need to touch up on your brushwork a bit. Also some of your lighting seems out of place.

And what level design pictures are you basing your opinion on? If you want me to understand your criticism you must first give me an example of an area that in your opinion lacks, and another example of an area that you think is a good level of detail concept for me to base other maps on, if any.

But bare in mind that most of these are work in progress, specially older pictures.
