Half-Life 2: Black Box Cheats (PC)

When you beat Portal, you will get a new title screen 

for the game, consisting of a birthday cake sitting atop 

a table.

Turn on the cheat console in-game, and press the 

tilde (~) to bring it up. You can then type the codes 

in below for the desired effect...

ai_disable - NPCs are turned off

give item_battery - Receive 15 battery 

points

points

All commands are done via the console. They must be 

enabled via the console option on shortcut, or enabled 

through the in-game options under the Advanced section 

of Controls.  It is then accessed by pressing ~. (Note: 

Most of these require sv_cheats to be set to 1.)

change_portalgun_linkage_id #

Replace # with 0, 1, 2, or 3. This allows for 

separate sets of portals to be created.

ent_create_portal_weight_box

Creates a Weighted Storage Cube for your use.

fire_energy_ball

Fires an energy ball that can be used in solving 

puzzles.

sv_portal_placement_never_bump 1

Self-explanitory.

sv_portal_placement_never_fail 1

Portals can be placed on almost any surface.

upgrade_portalgun

Will allow use of second portal placement.

This process modifies your game files, so make back-

ups of the proper files and directories before 

attempting this hack.

You need both Portal and Half-life 2 for 

starters. Install or re-install both games now.

 
Back up your Portal directory. Unless you 

changed the install path, the directory is in 

...\Steam\steamapps\(your_username)\portal. If 

you make a mistake during this hack, you may need to 

re-download Portal through Steam (or at worse, Half-

life 2 through Steam).

 
Download and install GCFScape if 

you do not have it already. This program allows you to 

access the cached game files for games using the Source engine.

 
Head into the directory 

...\Steam\steamapps\ for all the available GCF 

archives available. Open the file half-life 2 

content.gcf via GCFScape. Click the hl2 

folder on the left pane of the GCFScape Explorer 

window. Right mouse click maps  and select the 

command Extract to place all the contents of the 

maps folder into the directory 

...\Steam\steamapps\the_great_bundini\portal\portal<

/i>. This merges Half-life 2 maps with the Portal map 

folder.

 
Repeat the above step with the 

scenes folder via GCFScape.

 
Boot up Steam to run Portal. Drop the 

developer console with ‘~' (you may need to 

enable it under your keyboard options or enable it via 

the -console command switch on the executable's 

shortcut).

 
On the developer console, type maps 

* to list all the available maps; this should 

inclde the Half-life 2 maps imported from the previous 

steps. Type map and then the name of that map 

(i.e., map d1_canals_01).

 
Once the map is loaded and you can play, 

drop the console and enable the cheats for Portal by 

entering sv_cheats 1. Give yourself all weapons 

(including the Portal Gun) by entering impulse 

101. You may need to input upgrade_portalgun 

to enable you to fire both portals.

 
Enjoy the havoc. Note that this hack also 

works with Episode 1 and Episode 2. You will notice 

that while NPCs from Half-life cannot pass through 

portals, all other inert objects (including yourself) 

and weapons fire will pass through with no 

problems.
