Xash3D is the powerful independent open-sourced 3D-engine, aimed for high compatibility with GoldSource engine formats (maps, models, textures, sounds, entities etc.), but with the intention to be an advanced platform for modmaking or game development. Technically it has been built from a scratch, using as totally original ideas, as some ideas from other 3D-engines. Xash3D overcomes obsolete GoldSource engine's limits and provides for you a new quality of gaming experience and modmaking capabilities, as extended map, model, texture & sound formats with higher limits, possibility to implement custom renderers with dynamic lighting and other modern features. Xash3D is the easy-to-use base to play existing Half-Life mods & create something new, impossible with GoldSource. Years of development & testing allowed to make from Xash3D a perfect mix of high compatibility with common GoldSource standards & high openness to creative modmaking ideas.
Compared to what the mod is now, this is extremely old & does not represent the current state of the mod. I'll still leave it up for archival purposes, and just to look back on and ponder how much I've improved! Its here! This is the release running on Xash3D, I'd prefer you play this one over the Steam release for many reasons, NPC's lips sync properly with their lines, music doesn't cut off if you die, or reach a level change, and it just feels alot more stable then the Steam branch of GoldSrc. If there are any errors, let me know!
