Half-Life Episode Two mod

Plot:
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 an Half-Life 1 modification currently under development, the project focuses on creating a singleplayer adventure with improved and modernized gameplay elements, lots of exploration and action, with a eery and moody atmosphere as well as a deep and interesting plot while partially staying true to the original Half-Life gameplay.

With a reworked and improved game platform Half-Life Episode Two will feature lots of graphical improvements, extended gameplay elements, a new sound platform, professional standard level design, very high quality models and overall compelling presentation.

The game will not, as of currently, support multiplay.

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 Trinity rendering engine, which supports features like the following:

• Rewritten BSP renderer, with support for multipass per-pixel shaders, high resolution textures, vertex buffer objects, shadowmaps and detail textures;
• Rewritten Studio renderer with support for per-pixel shaders, high resolution textures, vertex buffer objects, shadowmaps, decals and Intel advanced instructions set;
• A Scriptable Particle engine widely used for advanced visual effects;
• Water Shader with reflections, refractions, fog and frustum;
• Client Prop manager that uses vertex buffer objects to load unlimited amounts of models into the video card;
• Fallback to legacy rendering is possible for older systems.

And other post processing effects not entirely related to Trinity such as:

• Aura Glowshells
• Motion Blur
• Screen Glow
• color effects
• Depth\Radial fog
• Caustic effects

To run this mod at its full quality and support with optimal performance, your system must meet the following recommended requirements:

• OpenGL 2.0 capable video card, Nvidia Geforce 6000 series or better with 256 Mb of dedicated video memory;
• Intel Pentium 4, 2.6 Ghz or better;
• 512 MB system ram.

The game is perfectly playable in all common graphics card types (Nvidia and ATI video cards). Intel graphics chips are also supported but are known not to perform perfectly. Nvidia 5 FX series are not entirely compatible. Other video card vendors were not tested and therefore are not guaranteed to work.

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