How to change your model in Half-Life 2

Step 1. Open your developer console.  This can be done by pressing the "~" key while you are in-game.  If a console windows does not appear when you press that button, then you should follow the instruction that can be found here.

Step 2. In the console window, type the following line: cl_playermodel "models/humans/group03/male_05.mdl"

NOTE: This will change your model to the male_05 model.  You can substitute and of the lines before for a different model.

Step 3. Press enter. Then close your console window.  Your player should now be wearing the new model that you just chose.

 

NOTE: There are a total of 18 player models for you to choose from.  9 Male, and 9 female.  In order to choose a female model, simply replace the word "male", with the word "female" in the line above. You may select other models by changing the "05" to some other number from 01 to 09 in the line above.  Or you can simply copy and paste the appropriate line from the table below.
