Is it original HL or is it something that came with CZ/CS:S? It has to be the original retail, as in HL1, Counter-strike Retail (the one you bought off the shelf), and it might even come with the 5 games (Half-life, Blue shift, Opposing forces... etc.)crodplaya said:well then could I install my friends HL1 GOTY Edition and would it work with that?
