The model of gordon in his car is not made by me. I took the model from Half-Life Azure Sheep. I made the script. The sounds of cardrive2 and truck_skid are from Asheep too. And the others are from own half life and blue shift. (Car doors sound)
To get in the car, sv_cheats must be on. Then write exec coxe.cfg in console. You'll hear some sounds at same time but they'll stop fewly. Now, move with W, A and D or S. To move faster press shift. To use the claxon press E. To get outta the car, press ENTER, you will hear a door sound, and the script will exec a default to restore the binds. This bind cfg is originalconfig.cfg You must extract the files on the valve directory if you take 'em all. If you copy valve directory, copy it in your half-life directory. -.-
Don't worry if windows asks you to replace files. Replace all of em.
