Update 14-3-2024: Added a texture from 0.52 that I forgot to include before...
Previously known as the Beytah Pack, this WAD contains a plethora of textures that are not in your average halflife.wad. This pack includes fascinating things such as Coca-Cola vending machines, pin-up posters, Albert Einstein, the mysterious Xen Nipple, and the many walls and floors hidden in the depths of Black Mesa.
The majority of the textures come from pre-release versions of Half-Life, as well as sources directly related to the game.
I hope someone will find some use out of this!
