Half-Life is a first-person shooter game developed and published by Valve. It came out in 1998 and tells the story of Gordon Freeman, a scientist at the Black Mesa Research Facility, who must survive an alien invasion when an experiment goes horribly wrong. If you want help tackling the aliens of Xen, add these codes for Half-Life cheats to your arsenal.
This guide is specifically for cheat codes on the PC version of Half-Life.
How to Enable Half-Life PC Cheat Codes
To enable the cheat console in Half-Life, open the game from the command prompt or a special desktop shortcut you create. Here's how to do that:
Locate the Half-Life shortcut on your desktop.
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
Add -console after the file. It should now look like this:
C:\Program Files\Sierra\Half-Life\hl.exe" -console
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.
How to Enable the Console Via Command Prompt
There's an alternate way to enable the Half-Life cheat console using the Command Prompt program. Here's how:
Go to Start > All Programs > Accessories > Command Prompt.
Type C:\Program Files\Sierra\Half-Life\hl.exe -console.
Press Enter.
Some versions of Half-Life enable the console by default.
How to Use Half-Life Cheats on PC
After the console is enabled, do the following to use cheats in Half-Life:
Start Half-Life with the console enabled.
Press the tilde (~) key to open the console.
Enter sv_cheats 1 and press Enter.
If this is the first time cheats have been enabled, cheats won't activate until you load a game, start a new game, or move to another level.
