Quick answer: Half life 2 console commands run on PC once you enable the developer console and type sv_cheats 1. Then use god, noclip, impulse 101 for all weapons or give item_healthkit for health. Press ~ to open the console.

Half life 2 console commands let you turn on god mode, fly through walls, give yourself every weapon and spawn enemies or allies. The console is the Source engine’s developer console, and cheat commands only work after sv_cheats 1.

Commands on this page were checked against a Half-Life 2 console guide, a Steam community thread on the Source console and the Valve Developer Community description of the developer console. Cheats are for single-player play. The Xbox 360 and PS3 versions have no typed console and use button codes.

How to open the Half-Life 2 console

Enable the developer console in the keyboard options, or add a launch option. You can use either method.

In Half-Life 2, open Options, then Keyboard, then Advanced.
Tick Enable developer console and apply.
Press the tilde key (~) in game to open the console. Press it again to close.

The launch option route is to right-click the game in Steam, open Properties, and add -console to the launch options. You can bind another key with bind F2 "toggleconsole". Commands can be chained on one line with semicolons.

The Steam thread that describes the Advanced menu was written for Half-Life: Source. The same menu route is given for Half-Life 2, and the launch option works for any Source game. The developer console is a PC feature.

Turn on cheats with sv_cheats 1

Type sv_cheats 1 before any cheat command. sv_cheats 0 turns cheats off again.

Cheats are flagged per session, so run sv_cheats 1 after you load a map if commands are rejected. Cheat commands are meant for single-player or LAN games. Forcing cheats on a multiplayer server you do not own can get you removed from it.

`map d1_trainstation_01`	Loads a map by name. This one starts the game.

Type noclip over solid ground. If you switch it off while inside a wall, you can get stuck.

Weapons, health and ammo

Use impulse 101 to get all weapons, give item_healthkit for health and give item_battery for suit power. givecurrentammo refills the weapon in your hand.

Other guides show give weapon_ar2 and give weapon_molotov for single weapons. Replace the name after give with the weapon class you want.

The supercharged gravity gun has a side effect. While physcannon_mega_enabled 1 is active, any NPC’s weapon disintegrates on death throughout the game.

Spawn NPCs and change allegiance in Half-Life 2

Use npc_create npc_<name> to spawn an NPC where you are looking. Example names are npc_combine_s, npc_metropolice, npc_strider, npc_zombie, npc_fastzombie, npc_headcrab, npc_alyx, npc_barney and npc_citizen.

ent_fire npc_zombie ignite sets that NPC type on fire.
ent_fire npc_combine_s setrelationship "PLAYER D_LI 99" makes the NPC type friendly toward the target. D_HT makes it hostile.
ent_create npc_combine_s model models/combine_super_soldier.mdl spawns an Overwatch Elite, which cannot be made with npc_create. Add additionalequipment weapon_<weaponname> to arm him.

Some NPCs need the episodes. npc_zombine requires Episode One or Two, and npc_hunter and npc_magnusson require Episode Two.

Other useful Half-Life 2 console commands

fps_max 0 removes the frame rate cap. The default is 300 and the engine tick rate stays at 66.666 Hz.
-novid is a launch option that skips the Valve intro video.
snd_legacy_surround 1 re-enables legacy surround mixing.
maxplayers 4; sv_lan 1, followed by map d1_trainstation_01, loads the campaign as LAN co-op. Autosaves will not load and dead players respawn.

Half-Life 2 console commands not working

Console will not open: enable the developer console in Options, Keyboard, Advanced, or add -console to the launch options. Check your layout; the tilde key moves on non-US keyboards.
“Can’t use cheat command”: run sv_cheats 1 first, after loading the map.
NPC does not spawn: check the class name, and remember that episode-only NPCs need those episodes. The Overwatch Elite needs the ent_create method.
Stuck after noclip: turn it off over solid ground only.
Command works but mods break: the 20th Anniversary update changed the engine and shaders. Old addons may need the legacy build branch on Steam.
Speedruns: console use is treated differently by speedrun rules. Use these commands for sandbox play, not for leaderboards.
