SoHL v1.8 Alpha 1, compatible with visual studio's 2010.
Spirit of Half-Life (SoHL) is a modified game engine for Half-Life 1 modders that includes many new things not seen in the original Half-Life engine by Valve. This includes reflections, mirrors better lighting, weather like moving clouds, rain, snow, and fog. Physics capabilities like picking up objects and dropping them, or when some thing explodes objects go flying off in the direction.
Basically all SoHL versions are ready for download versions:
1.2 (now has source code)
1.6 (still need to find source code )
1.8 (now has source code )
All versions work so don't complain if a version doesn't have something, because either its too old or you have to code it yourself.
SoHL v1.8 with source code and its compatible with visual studio 2008!
