Half-Life 2 Cheats, Guide

Half-Life 2 is a 2004 first-person shooter game developed and published by Valve. Like the original Half-Life, it combines shooting, puzzles, and storytelling, and adds features such as vehicles and physics-based gameplay. Players control Gordon Freeman, who fights the alien Combine with allies including resistance fighter Alyx Vance, using weapons such as the object-manipulating gravity gun.
Cheat codes, console commands, secrets:
In order to enter the following cheats you will have to activate
the console by modifying game shortcut. Right-click on the Half-Life
2 icon on your desktop, select Properties and a new screen should
pop up. Add the " -console" parameter (without the quotes) at the
end of the target field so it looks similar to this:

"C:\Program Files\Half-Life 2\hl2.exe" -console

Click Apply to save the changes and run the game using that shortcut.

Bring DOWN the console[~] and enter "sv_cheats 1".
