Half-Life 2: Cheat Codes.

This guide was created to help players properly use the console and its commands.

Basics.

The first thing you should do is ensure that the console is enabled.
1) After starting up Half-Life 2. Click "Options".
2) Then click "Keyboard".
3) Now click "Advanced" and make sure that "Enable Developers Console" is enabled!

Now. Before entering any cheats. You must have "sv_cheats 1" enabled.
Just press "~" and type into the console, "sv_cheats 1".

You are now ready for you're cheats!

Spawning NPC's.

This section of the guide will show you how to spawn NPC's! (Non-Playable Characters)
Hit “~” and type "npc_create npc_ [name]” to spawn an NPC. Replace "[name] with the code. Here is a list of codes you can enter for [name]:

Remember! Where you're pointing is where the NPC will spawn!

Spawning Weapons.

Before wasting your time reading all of this. Please keep in mind that you can simply type "impulse 101" and It will automatically give you a stock of all the weapons in the game. This includes giving you the weapons themselves and the ammo. If you type "impulse 101" again, It will give you ammo.

OK! Before giving yourself anything. You MUST type into the console "give [weapon]." Here is a list of [weapon]'s you can use:

weapon_357
weapon_bugbait
weapon_crossbow
weapon_annabelle
item_dynamic_resupply
weapon_crowbar
weapon_smg1
weapon_ar2
weapn_pistol
weapon_rpg
weapon_shotgun
weapon_physcannon

Remember! You don't need to type "give impulse 101" for the full-stock of weapons and ammo. Its just "impulse 101".

Please note: weapon_physcannon is the Gravity Gun. Once you have the Gravity Gun, type this: "physcannon_mega enabled 1" into the console to turn your Gravity Gun into a Modded Gravity Gun or "Mega Gravity Gun"

Spawning Ammo.

This is related to "Spawning Weapons". Just type "give [ammo]" Heres a list of [ammo] you can use:

item_ammo_357
item_box_srounds
item_ammo_crossbow
item_box_lrounds
item_ml_grenade
item_box_buckshot
item_box_mrounds
item_ar2_grenade

"Spawning Weapons." and "Spawning Ammo." are both related. So I highly suggest you read "Spawning Weapons." before reading this section.
