Big Sandbox

It is almost as big as I can do with the program I'm using

This download looks like a map. You need to place it in your maps folder inside the Garry's Mod folder.

You should end up with a directory structure similar to below

  • steamapps
    • common
      • garrysmod
        • garrysmod
          • maps
            • GmodMap10.bsp

Don't know where the Garry's Mod folder is or how to extract zip files? See more useful installation tips.
