The March 2025 Update is now live.


This update brings some new content to Sandbox:
There are also further localization improvements to the Sandbox gamemode, more English-only phrases are now translated to player's selected language.

We also have a new mountable game, at the request of its developer:
https://store.steampowered.com/app/1786950/Klaus_Veens_Treason/

Players will be able to use maps, models and other assets from this game in Garry's Mod, once mounted through Main Menu's Games section.

This update also adds a large number of new entities to the game, mostly from newer Source Engine games. This should help mappers create even better maps, and potentially improve compatibility with maps from mountable games.
In addition, there were some improvements to the Hammer editor and map compilation tools, further benefitting mappers.
This update also brings partial custom shader support, enabling modders to create fancy effects such as this:
As usual, there is a large number of Lua API additions and fixes, as well as other miscellaneous fixes and improvements for modders as well as players.

This update requires servers to update before you can join them.

This means that for a certain period of time after the update releases you may be unable to join servers and get a message saying "The server is running an older version of the game" instead. You will have to wait for servers to update before you can join them again, as well as make sure your game is up to date.

You cannot downgrade to a previous version of the game. Please be patient and let server owners update their servers.

Hello everyone,

The next Garry's Mod update is coming soon.

The current plan is to release the next Garry's Mod update on 26th of March at 3PM GMT.

The update will be mandatory for all server owners, so write the date down, servers will need to be updated before they can be joined again.

You can preview the list of upcoming changes here:
https://wiki.facepunch.com/gmod/Update_Preview_Changelog

Please note this list is still work in progress and is subject to change.

We kindly ask anyone willing to help us, players, modders and server owners alike, to test this update before it releases, to minimize any potential problems on release day.

Just run your game or your (development/test) server on one of the beta versions briefly to see if any new issues crop up compared to the non-beta version of the game.

The Pre-Release Steam beta branch for Garry's Mod has been updated and contains all the changes that will be included in the next update. The "dev" and "x86-64" betas also contain all the upcoming changes.

You can report any found issues preferably on our official bug tracking repository on GitHub: (be sure to search before posting)

Or at the very least in the comments below, or on our official Discord server or:

If you wish to set up a dedicated server instance using any of the beta branches, please see this article: https://wiki.facepunch.com/gmod/Downloading_a_Dedicated_Server

How to switch game branches:

1. Exit the game
   
2. Right click on Garry's Mod in Steam and select Properties
   
3. Go to the Betas tab and select your desired branch

None - This is the normal version of the game
Pre-Release - This is the next update
Dev - This is a bleeding edge version of the game, expect it to contain more bugs than usual
