Half-Life 1 Cheat Codes: All Console Commands — impulse 101, god, noclip (2026)
Half-Life is the game that started the Valve legend: scientist Gordon Freeman, the Black Mesa complex, cascade resonance and the crowbar. The 1998 shooter is still played by thousands of players - both the original and the remake of Black Mesa. The game has a full set of cheat codes via the console: we have collected all the working commands with descriptions.
How to turn on the console in Half-Life
- Launch the game with the -console parameter (on Steam: right-click on the game → Properties → Launch Options → enter -console) or enable the console in the keyboard settings.
- In the game, press tilde ~ (Y).
- Type sv_cheats 1 and press Enter - cheat mode is enabled. If the command says that cheats are not available, load any save and enter it again.

Frequently asked questions
- Do the codes work in Black Mesa? Yes, a remake on the same Source engine: sv_cheats 1, god, noclip and give commands work, the weapon names are mostly the same.
- Can't enter codes? Check the -console parameter and that sv_cheats 1 is entered after loading the save, and not in the main menu.
- Codes for Half-Life: Source? The same ones, plus HL2 level commands (impulse 101 is identical).
