Ah thanks.. I was feeling a bit uncomfortable posting it, since most of the layout eg. the cliffs were done in HL1 editor, so they won't look as professional as one could make them for HL2. Nevertheless, I thought it was a worthwile conversion.
I realised this was a good step for me, adding the map to the Pit, because now I HAVE to finish it

otherwise it would have been left behind like all the other projects.
