Guidance was intended as an entry for a TWHL competition. Due to school, wich just started during the competition time, I haven't been able to put in all features. While the competition was all about glas, I've only put in one glass feature... but some other stuff too, wich I think can be quite interesting.

So while this map doesn't really offer an interesting gameplay, there's some effects in it that make it worth a look: volumetric light, random fire and some glass stuff.

Oh, and be aware that it's put in mod-form, so you can just extract it to your Half-Life folder. Also, run HL with 32bpp, for best appearance of the volumetric light.
