Extract the materials folder from the RAR file.
Put the ct_urban folder in the
C:\Program Files\Steam\steamapps(your user name)\counter-strike source\cstrike\materials\models\player
If you don't already have this folder, create it.
Simply delete the ct_urban folder. Steam will replace the model with the original once you reboot counter-strike: source.
Have fun! Feedback welcome.
Valve for supplying the framework for the texture
and cssShreddeR for the edit.
