I’ve recently stumbled upon some sound files in the Counter Strike folder. (Not the Source version, the GoldSource one).
It is a cut map. There may be map and texture files, but I haven’t looked yet.
Here are a few interesting files:
torn_ambience.wav (wind whistling)
After adding it all up, I beleive it was supposed to take place in a destroyed Asian city, similar to that Call Of Duty Modern Warfare 2 level, however it’s name escapes me for the moment.
