GMod Game Mounting 2021
GMod game mounting allows certain source games to be added into gmod so that their content can be used! This tutorial will show you how to mount these games to gmod
*REMINDER* MAKE SURE BOTH GMOD AND THE SOURCE GAMES ARE UPDATED.
1. Open GMod. At the main menu, select the controller icon at the bottom right.
2. Select the games that you would like to mount. As you can see, I can mount source and CSGO.
3. Restart GMod, load up single player, and enjoy!
