how to turn on cheats for Half Life

1: locate the Half-Life shortcut on your desktop.

2: Right-click the Half-Life shortcut, then select Properties. The file location displays in the target field. It might look similar to this:

C:\Program Files\Sierra\Half-Life\hl.exe

3: Add -console after the file. It should now look like this:

C:\Program Files\Sierra\Half-Life\hl.exe" -console

4. Press OK to save the changes and close the window.

5. If you own a Game of the Year version of Half-Life, enter one extra command parameter called -dev. So, the shortcut or path will look like this:

C:\Program Files\Sierra\Half-Life\hl.exe" -dev -console

Press OK to save the changes and close the window.
