How to Use the Portal Gun in "Counter Strike"

The games "Portal" and "Counter-Strike" have a few things in common; among them include the fact that they were made by Valve and run on the Valve-created Source Engine. Because they run on the same engine, it is possible to use data from one game in the other by editing a few key files. In particular, you can use the infamous Portal Gun while playing "Counter-Strike." This process requires the unique program called GCFScape, which enables editing on the game's source files.

• 1

  Download and install GCFScape (see Resources).

• 2

  Open your Steam directory. This is where you installed Steam, most commonly under "C:\Program Files\Steam." Double-click "steamapps" to open the folder. Double-click "counter-strike.gcf," and GCFScape will open this file.

• 3

  Navigate to the "maps" folder in the "cs" folder via the left-hand pane. Right-click "maps" and choose to "Extract." Click to extract in "portal\portal." Repeat with the "scenes" folder within "cs."

• 4

  Launch "Portal." Press the tilde (~) key and type in the following commands:

  map x

  sv_cheats 1

  impulse 101

  Change "x" to the name of any "Counter-Strike" map. For example, to open the "Estate" map, type "map cs_estate." This will load a "Counter-Strike" map, and you will hold the Portal Gun by default.
