Theseare 64-bit DLL files compiled from FWG's HLSDK-Portable Github page. These files are required for the amd64 build of the Xash3D Engine to be able to launch. They are not compiled by default unlike the 32-bit version.
2. After Clicking "testing" in the instructions on GitHub, download "xash3d-fwgs-win32-amd64.7z " since that is what these files are for, they are not need for the I386 build (x86) and will not work in MAC or Linux builds. Extract that archive somewhere on your system.
