Garry's Mod

The Garry's 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 Hunt's elaborate, shape-shifting game of Hide & Seek. Elevator: Source is gaming's first elevator thrill ride, delivering players to airlocks and kitten dance parties.

We have one of the most vibrant Steam Community Workshops, with over 300'000 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: it’s 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.
