Half-Life 2 Console Commands & Impulse Cheats List 2026 (God Mode & Weapons)

How to Enable and Access the Developer Console in Half-Life 2

Enabling the debug console in Half-Life 2 can be accomplished through the in-game options menu or via Steam launch parameters.

Method 1: In-Game Options Menu

1. Launch Half-Life 2 from your Steam Library.
2. From the main menu, click Options > Keyboard.
3. Click the Advanced... button in the bottom-right corner.
4. Check the box labeled Enable Developer Console (~) and click OK, then Apply.
5. Press the tilde key (~ or `) directly below Esc to toggle the console window.

Method 2: Steam Launch Option (-console)

If you use a non-standard international keyboard layout where the tilde key does not register:

• Open your Steam client and right-click Half-Life 2 in your Library.
• Select Properties... and locate the Launch Options text field.
• Type -console into the box.

When you start the game, the developer prompt will open automatically over the main menu, allowing immediate execution of commands or custom keybindings.

Master Cheats and the Legendary Impulse Codes

In Valve's Source engine, the primary gateway to cheat execution is sv_cheats 1. Once enabled on any loaded campaign map, classic impulse routines become operational.

Impulse 101: The Ultimate Arsenal Drop

Typing impulse 101 is the most iconic cheat code in PC gaming history. Entering it instantly executes a comprehensive gear grant:

• Awards Gordon Freeman the Crowbar, 9mm Pistol, .357 Magnum, MP7 Submachine Gun, AR2 Pulse Rifle, SPAS-12 Shotgun, Crossbow, and RPG Launcher.
• Fully replenishes all secondary ammunition reserves, including underbarrel SMG grenades and AR2 energy dark matter orbs.
• Maxes out explosive supplies with full loads of Frag Grenades.
• Fills Gordon's HEV Hazard Suit power gauge to 100 armor protection.

Impulse Vehicle Spawning (Scout Car and Airboat)

Half-Life 2 features extensive vehicle chapters. If your vehicle flips into an unreachable canal, becomes stuck in toxic sludge, or detonates, built-in impulse routines summon a replacement instantly:

• impulse 82: Spawns the Scout Car (the rugged yellow Buggy with mounted tau cannon) directly in front of Gordon.
• impulse 83: Spawns the propeller-driven Airboat craft directly on the water surface.

The Supercharged Blue Gravity Gun (Dark Energy Overhaul)

During the climactic final chapters inside the Combine Citadel, the Confiscation Field supercharges Gordon's Zero Point Energy Field Manipulator with dark energy, turning its orange emitter blue and allowing it to grab organic enemies.

Unlocking the Super Gravity Gun Anywhere

You do not need to wait until the end of the game to wield this godlike weapon. With sv_cheats 1 active on any level, open the console and type:

physcannon_mega_enabled 1

Your Gravity Gun will immediately transform into the blue Supercharged version. In this state:

• You can pick up live Combine soldiers, Metropolice officers, and Striders from distance.
• Discharging the primary fire vaporizes organic targets instantly into dissolved ash.
• You can pull heavy metal consoles, engine blocks, and security doors directly off walls to use as kinetic battering rams.
• To return the weapon to its standard orange version, enter physcannon_mega_enabled 0.

Survival Toggles: God Mode, Noclip and Enemy Stealth

Navigating heavy Combine gunship ambushes or claustrophobic poison headcrab tunnels in Ravenholm can test any player's endurance. Foundational survival toggles grant complete immunity:

God Mode (god) vs. Buddha Mode (buddha)

• god: Complete invulnerability. Gordon takes zero damage from Combine pulse fire, helicopter carpet bombing, falling off towering bridges, and green radioactive sludge.
• buddha: Gordon takes incoming damage and flinches realistically, but his health gauge will never drop below 1 HP, preventing death while preserving combat urgency.
• give item_healthkit: Spawns an emergency first aid kit to heal 25 hit points.
• give item_battery: Spawns an HEV power cell to recharge 15 armor suit points.

Noclip Flight and Stealth Invisibility (notarget)

• noclip: Enables zero-gravity flight through solid walls, steel doors, and level geometry. Essential for bypassing locked progression gates or exploring skybox architecture.
• notarget: Renders Gordon Freeman completely invisible to enemy AI. Combine soldiers, automated floor turrets, and Gunships will refuse to fire upon you.

Full Firearms Arsenal and Equipment Identifiers

If you wish to equip specific firearms rather than using impulse 101, the give command spawns individual weapons:

• give weapon_crowbar: Spawns Gordon's iconic red crowbar for silent crate smashing.
• give weapon_physcannon: Equips the Zero Point Energy Field Manipulator (standard Gravity Gun).
• give weapon_shotgun: Spawns the dual-shot combat shotgun for lethal close-quarters stopping power.
• give weapon_357: Spawns the high-precision six-shot Magnum revolver.
• give weapon_smg1: Spawns the MP7 submachine gun with high rate of fire.
• give weapon_ar2: Spawns the Combine Overwatch pulse rifle with ricocheting plasma balls.
• give weapon_crossbow: Spawns the scoped sniper crossbow firing red-hot rebar rods.
• give weapon_rpg: Spawns the laser-guided rocket launcher to destroy Gunships and APCs.
• give weapon_bugbait: Spawns Pheropods to summon and direct friendly Antlion guards.

Custom Ballistic Damage Tuning and Skill Overrides

The Source engine exposes granular skill-variable parameters (sk_) that regulate weapon damage, enemy hit points, and ammunition capacities:

• sk_plr_dmg_ar2 [Value]: Sets damage per pulse rifle bullet. The default value is 8. Setting this to 50 creates an ultra-lethal military rifle.
• sk_plr_dmg_crossbow [Value]: Adjusts crossbow damage. Setting this to 500 pins any Combine soldier or elite officer to distant walls instantly.
• sk_plr_dmg_crowbar [Value]: Increases crowbar melee damage. Elevating this to 100 allows Gordon to smash armored zombies in a single swing.
• sk_max_ar2_altfire [Value]: Increases maximum dark matter plasma energy spheres carried in inventory.

NPC Creation, Enemy Spawning and AI Manipulation

The Source engine features a flexible entity spawning architecture that lets you stage massive sandbox firefights between Combine forces and resistance fighters.

Spawning Enemies and Creatures (npc_create)

Aim your crosshair at the ground where you want the entity to appear, open the console, and type:

• npc_create npc_combine_s: Spawns an armed Combine Overwatch assault soldier.
• npc_create npc_metropolice: Spawns a City 17 Civil Protection officer with stun baton or pistol.
• npc_create npc_strider: Spawns a massive walking tripod Strider war machine with heavy laser cannon.
• npc_create npc_zombie: Spawns a standard Headcrab Zombie.
• npc_create npc_fastzombie: Spawns an agile, screeching Fast Zombie from Ravenholm.
• npc_create npc_poisonzombie: Spawns a lumbering Poison Zombie carrying multiple deadly headcrabs.
• npc_create npc_antlion: Spawns an aggressive Antlion bug.
• npc_create npc_citizen: Spawns an armed human resistance fighter to aid Gordon.

Controlling NPC Cognition and Behavior

• ai_disable: Freezes all AI thinking globally. Enemies and allies freeze completely in place.
• ai_show_connect: Displays underlying pathfinding navigation nodes rendered across the geometry.

Chapter Warp Codes and Map Progression Navigation

If you wish to jump directly to iconic set pieces without replaying earlier sections, the map command loads any level in the game:

• map d1_canals_01: Launches Chapter 3 (Route Kanal) with early Airboat piloting.
• map d1_town_01: Warps Gordon directly to the start of Chapter 6 (We Don't Go To Ravenholm).
• map d2_coast_01: Loads Chapter 7 (Highway 17) for open-road Buggy cruising.
• map d2_prison_01: Transports you to Nova Prospekt to command Antlion armies.
• map d3_c17_01: Initiates the urban street fighting revolution in City 17.
• map d3_citadel_01: Warps Gordon into the heart of the Combine Citadel with the Supercharged Gravity Gun.

Physics Engine Manipulation and Gravity Experiments

Half-Life 2's Havok physics engine was revolutionary upon release. You can alter physical impact forces and ragdoll interactions to stage hilarious sandbox reactions:

• phys_pushscale [Value]: Adjusts how forcefully objects are launched when struck by Gordon or weapon blasts. Increasing this to 5 or 10 turns wooden crates and metal barrels into high-velocity projectiles that send Combine squads flying across City 17 plazas.
• cl_ragdoll_collide 1: Enables physical collision between fallen ragdoll corpses, preventing bodies from clipping through one another when piled in narrow doorways.
• r_drawviewmodel [0/1]: Toggles the first-person weapon model on or off. Disabling viewmodels creates an ultra-clean camera view for scenic walkthroughs.
• viewmodel_fov [54-75]: Adjusts weapon perspective distance from the screen. A value of 65 offers a balanced, modern weapon model presentation.

Simulation Speed, Bullet Time and Visual Debugging

For content creators or players who love dramatic cinematic shootouts, Source engine timescale parameters allow fluid bullet-time mechanics:

• host_timescale [Value]: Adjusts game simulation velocity. Typing host_timescale 0.5 cuts world speed in half, allowing you to watch rocket trails and ragdoll physics in majestic slow-motion. Type host_timescale 1 to return to normal speed.
• default_fov [60-110]: Sets the camera field of view. Setting default_fov 90 provides a modern widescreen perspective without fisheye distortion.
• mat_wireframe 1: Displays 3D wireframe polygons across the map to inspect how Valve constructed City 17's brushes and occlusion volumes.
• cl_drawhud 0: Hides the HEV suit HUD, crosshair, and ammunition counters for pristine cinematic wallpaper captures.

Authentic Gameplay Experience: Pros and Cons Analysis

Steam Achievement Rules and Save Integrity Guidelines

In Half-Life 2 on Steam, activating sv_cheats 1 disables achievement tracking for the duration of that play session.

How to Restore Steam Achievement Tracking

Achievement disablement is temporary and strictly session-bound. Entering cheats will not flag or permanently taint your campaign save files. To continue earning Steam achievements:

1. Use your desired console commands (e.g. unsticking your vehicle or testing a weapon).
2. Create a manual save from the main pause menu.
3. Completely quit Half-Life 2 back to the desktop.
4. Relaunch the game from Steam without opening the console or enabling cheats, and load your save. Steam achievements like Submissive, Zombie Chopper, and Blast from the Past will unlock normally.
