here's a quick port of Xash3D (half-life open source clone) to Windows RT.
This should also work under Windows 10 ARM (without x86 emulation layer).
NOTE: You still need the original data files of Half-Life to run the game (the contents of 'valve' folder), which is NOT included here.
Source Code is included.
