I've heard it is possible to play with Half Life making some tricks. But all of them requires the presence of the console window. I pulse the key "º" during the game, but no console window is showed. I have seen some people make a shortcut with a direct access to ""Calf-Life\hl.exe-dev-console" in order to enable the console window. But the computer says to me this archive is unknown. I've searched for it and I've not got it in C:. What can I do in order to display the console window?. Thanks.
