download HLRA for developing dated July 6, 2025. [340 Mb in .7z archive].

Program requirements for work: it is necessary to have Half-Life 1 versions 1.1.1.0 or higher (certainly, except Half-Life 2). Under Windows 95 or higher with DirectX 8 or higher. It is desirable, that in shared folder Half-Life instead of standard libraries hw.dll and sw.dll (are responsible for hardware and software graphics drawing) dll-libraries from DoD were used — they are in addition capable to display the set parts of models with an additive transparency and a transparency alpha mask. Download that libraries hw.dll and sw.dll here.
download Half-Life update to version 1.1.1.0 (for non Steam H-L) [80.6 Mb in .7z archive].

It is the playable version of HLRA mod for developers. In this version, there are two alternative stories — these are the initial maps with the prefix !, starting with intro... maps, then maps !lenin1.bsp and etc. and interrupted by the neb3.bsp map; and an alternative history, which was created by Mig-29 and ObaGlaza and also begins with intro... maps, then lenin1.bsp, lenin2.bsp, lenin3.bsp and is interrupted by lenin3b.bsp, since the lenin4 map starts from the basement, until the transition there is made.

What new in this version in relation to an old demoversion in which already a lot of things was made:
   New maps are added and almost all old maps are finished. Additional space is added on many maps. But the most part of maps didn't enter to this version, after all as it was told it is the special cut-down version.
   New objects including monsters and the weapon are added.
   New models are created and the existing are finished.
   Background music is added. Sometimes.
   We are rephrased of soldiers and special player suit (HEV). Partially sounds of scientists and security are remade. New ambience sounds. The sounding of objects (some trains, doors, buttons, breaking objects) is also changed.
   Many new textures is created and the existing are altered.
   New sprites are added and existing are updated.
   There was a game stock now. It can be switched by [ and ] keys. Plus that in general isn't so important, the splash screen and other game trifles changed.

Despite a basic purpose, you certainly can play or put in it experiments. But after all we wait for you in the Guest book. Our general e-mail — .


download graphic effects library QeffectsGL for Quake/Half-Life engine by Xaerox [63 Kb in .7z archive]. This .dll library should be placed in a folder with hl.exe file. It adds several graphic effects such as Bloom, HSL color correction, Multisample anti-aliasing (and in some cases Depth of Field, Screen-space emboss bump-mapping and Screen-space ambient occlusion (but SSA occlusion doesn't work good in HLRA)). You can use it if you want to see them.
Examples of images from many maps of game are in SCREENSHOTS site section.
