The November 2025 Update is now live.

This update adds new water rendering features from newer Source Engine games to Garry's Mod. Here's a comparison:

This includes flow maps, lightmaps and ability to reflect 3D skybox. This both improves compatibility with mountable games, as well as enables map makers to use these new features in their maps.

It must be noted that these changes may unexpectedly affect a small amount of existing maps. The issue here is that some map makers are using (modified) water materials from other Source Engine  games which have parameters that did not previously work, but do work correctly now, causing unexpected changes in water appearance. This is unfortunately unavoidable from our end, and will need to be individually fixed by map makers by editing their water materials. No map recompilation needed.

Another port from newer Source Engine games is the 4-way blend shader.

This is also going to help map makers make better looking maps, easier.

A long standing issue from the very inception of Garry's Mod was the lackluster support for weapons used by NPCs, especially when NPCs use weapons that they never used in Half-Life 2. This update finally addresses these issues.

NPCs no longer T-pose when trying to use non default weapons, such as Metrocops using RPGs or AR2s, Combine Soldiers can not only use all the built-in weapons without issue, but also run around and chase the player with no weapons. Citizens no longer stand up to shoot when crouched.

More NPCs can now use weapons as well, providing more options than ever.

With improvements to duplicator support for Half-Life 2 entities, Resistance-hacked Combine Mines are now available from the spawnmenu, and both it and the Flechette Gun are now available for all players, regardless of what games are mounted.

Faceposer got some minor improvements with the ability to randomize or clear only a specific category of sliders:

And an option for Spawn Menu and Context Menu keys to act as a toggle has been added to the Utilities panel:

As per usual, this update also brings a set of under the hood fixes and optimizations, and of course a number of new Lua API features have been added.

Hello everyone,

The next Garry's Mod update is coming soon.

The current plan is to release the next Garry's Mod update on 12th of November at 3PM GMT.

This update will be backwards compatible with existing servers, so servers will not need immediate updating and players can still join old servers, but it is still highly recommended to update as soon as the update releases to get all the new features and fixes.

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)

https://github.com/Facepunch/garrysmod-issues

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:

How to switch game branches:

• Exit the game

• Right click on Garry's Mod in Steam and select Properties

• 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
