Garry’s Mod is a physics sandbox. There aren’t any predefined aims or goals. We give you the tools and leave you to play.
You spawn objects and weld them together to create your own contraptions – whether that’s a car, a rocket, a catapult or something that doesn’t have a name yet – that’s up to you. You can do it offline, or join the thousands of players who play online each day.
