My first torrent, so please mention if I do anything wrong.
A pack including the four GCF files required to run the original Half-Life in Steam. Once downloaded, put all four files in your 'steamapps' folder inside your cracked steam and Cracked Steam clients can be found at CS.RIN.RU, in the releases subforum.
If the game fails to play, it's likely to be caused by the GCFs being out of date. Look for CFToolbox 1.0.10 on CS.RIN, and update them using that. If that y doesn't work, then again, CS.RIN.RU could probably, once again, help you out.
