Garry’s Mod is more than just a sandbox. It’s a whole polygon where you can test your creations after making them! Thanks to a wide range of tools, you can come up with literally anything, from a steampunk device to a futuristic weapon. You can also configure the environment where you will test it by adding any objects and structures to it. Every little detail is adjustable, so prepare to spend hours streamlining your brainchild. It’s going to be so much fun!
