Initially a Half-Life 2 fan-made mod, this sandbox editor gives you the tools to play with items and physics within the Source engine. It became retail on Valve's Steam game download delivery system with version 9.1.

You can pose rag dolls (position people and change their faces) then create a comic book by taking pictures of the results. Take props and weld them together to make walls, axis a wheel to it to create a working car, and rope some cans to the back. In fact, make any contraptions you can think of like Rube Goldberg machines (complex devices that perform simple tasks in indirect, convoluted ways), catapults, cannons, bridges etc.

By using the Lua scripting language, users can also create their own weapons and game modes which can completely change the genre of the game. Some examples are Roleplay, Stranded, SpaceBuild, Melonracer, and Zombie Survival. Game servers for Garry's Mod will automatically send their custom content to the client when joined.
