Counter-Strike: Source Garry's CS Mod v7a
 

This incarnation of the popular Garry's Mod for Half-Life 2 now comes to Counter-Strike: Source where you can pose ragdolls, create vehicles, or shoot melons, essentially turning the Source engine into your own virtual sanbox. With this version you will have access to maps and models from CS: Source.
