The July 2017 Update Will Be Released Next Week

Hey, we're planning to push the next Garry's Mod update next week on 2017-07-10. There's quite a lot of changes, so if you're running a server you'll probably want to at least try it out.

The update may not look like much, but I'm hoping that these internal changes are going to help us bring some more interesting updates in the future.

Pre-release Steam Branch
The Pre-Release Steam branch for Garry's Mod has been updated and contains all the changes that will be included in the next update. It is backwards compatible with the current version of the game, so if you are using it you'll still be able to connect to servers that haven't updated.

There will be instructions at the bottom of this post on how to join the Pre-Release branch.

Changelog
Windows builds of the game now use the Visual Studio 2017 C++ Runtime. This should hopefully not affect anybody, but could perhaps break some third-party binary modules.

Linux builds of the game now depend on GLIBCXX 3.4.19. You may run in to some issues if your server's C++ runtime is a decade out of date. Steam should handle this for you if you're just playing the game.

Game Changes
NEW - Preset support for Utilities menus

  3. Go to the Betas tab and select your desired branch
None - This is the normal version of the game

“It brings back the silly glee of unbridled experimentation, intuitive learning and playful social interactions that most of us haven't experienced since childhood. For that, it's essential.”

About This Game

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.

If you're not too great at construction - don't 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 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.
