About This Game
Garrys Mod is a physics sandbox. There arent 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 thats a car, a rocket, a catapult or something that doesnt have a name yet - thats up to you. You can do it offline, or join the thousands of players who play online each day.
If youre not too great at construction - dont worry! You can place a variety of characters in silly positions. But if you want to do more, we have the means.
Beyond the Sandbox
The Garrys Mod community is a tremendous source of content and has added hundreds of unique modes to the game. In Trouble In Terrorist Town, you can be a detective solving an online murder as criminals attempt to cover up their homicides. Be a ball, a plant, a chair, or anything else in Prop Hunts elaborate, shape-shifting game of Hide & Seek. Elevator: Source is gamings first elevator thrill ride, delivering players to airlocks and kitten dance parties.
We have one of the most vibrant Steam Community Workshops, with over 300000 models, maps, and contraptions to download. It has everything from new tools to improve your builds, to guns that fire rainbow-tinged nuclear blasts from space. Take as much or as little as you need: its all free.
Please note: Some multiplayer servers and game-modes might require you to own other games - such as Counter-Strike: Source and Team Fortress 2.
