This is a patch for so called "beta" version of Half-Life 2. The first version was made back in 2008, along with two more versions of it later on. This patch is a compilation of all known fixes and improvements made in the past for the "beta" by different authors. Currently we are working on a fourth version, which will literally fix almost all problems in "beta" caused by its content (such as models, textures, scripts, scenes).
