CS: Source Garry's Mod V7A

This is a new version of Garry's Mod that allows you to use content from Counter-Strike Source. The download is around the same size as the Half-Life 2 version of Garry's Mod. The only difference is that you won't be able to play Half-Life 2 single player maps in the CS:S version.

But don't worry - both can co-exist on your system quite happily! So seriously - don't worry! :D
