Garry's Mod

New mountable games

With community effort and permission from the respective game developers, 2 new games are now available to be mounted in Garry's Mod: Black Mesa and Military Conflict: Vietnam!

As with other mountable games, you will need to own them on Steam first, which will enable players to use maps and models from these games in Sandbox and other gamemodes.

HUD Improvements

Some default HUD elements received some polish - the weapon selector, damage indicators, health and ammo displays.

The ammo HUD now correctly displays ammo for certain modded weapon types that use secondary clips, the default weapon selector can now display more slots and scroll weapon selection when there are too many weapons equipped to fit on the screen.

The HUD now also scales better at 4K resolution, preventing certain elements such as Sandbox notifications and voice chat from overlapping the ammo HUD.

New content & content fixes

The Combine APC is now a built-in vehicle, right in the spawnmenu, fully driveable by the player.

There are also numerous bug fixes to existing models for various issues such as props becoming pitch black when resting on ground, fire effects not displaying correctly and spawning wrong gib models when broken.

Network protocol changes

This update brings significant under-the-hood changes to the game's networking, enabling faster network transfer speeds to reduce server join times, and removing a whole host of unnecessary networking done by various entities, hopefully reducing overall bandwidth usage, especially on initial player spawn.

This update also switches many game systems to use double precision time, which should help servers to not need to restart or change maps as often and improve overall game feel after playing for a while on the same map.

Smaller stuff

As usual this update also brings a huge amount of fixes and other smaller changes. Some optimizations to performance and memory usage as well.

You can find the full change list for this update in our blog post:

Hello everyone,

A new small patch has been released.

This one contains mostly fixes for regressions introduced by the November Update, as well as some other minor fixes.

Sandbox servers and clients are recommended to update at their earliest convenience.

The change list is as follows:

The November 2025 Update is now live.

New water visuals

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.

4-way blends

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.

Built-in NPC improvements

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.

Sandbox improvements

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:

Other stuff

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.

You can find the full change list for this update in our blog post:

https://gmod.facepunch.com/news/november-2025-update

Artwork Showcase - "The Construction"

The July 2025 Update is now live.

Update Highlights

The biggest user-facing change in this update brings most of Counter-Strike: Source and Half-Life 2 Episodic content to Garry's Mod by default, with gracious permission from Valve. This means that you no longer need to own those games and have them installed to play on community maps that expect you to have this content.

Please do note that maps from those games are not included, so you'll still need to install those games to use their maps, and neither are voice over files and music, due to licensing issues.

This won't eliminate all instances of missing content (missing textures and ERROR models), but it will address a majority of instances of this issue. The remainder would just be addon authoring or installation errors.

This also means that Half-Life 2: Episode 2 content is now available in the spawnmenu for every player by default.

As usual, there is a large number of smaller changes - crash fixes, optimizations, additions, as well as other miscellaneous improvements for modders as well as players.

You can find the full change list for this update in our blog post:

https://gmod.facepunch.com/news/july-2025-update

Hello everyone,

A new patch has been released. This one contains mostly stability and security fixes.

Servers and clients are recommended to update as soon as possible. The change list is as follows:

• Throw a non halting Lua error when hitting Lua file limit, to let players know that they have hit the limit

• Fixed a regression crash on Linux when almost finished loading a map

• Prevent crashes with steamworks library when used too early on dedicated servers

• Fixed console spam about invalid sprite orientation when the sprite material is simply missing

• Fixed HLTV clients being kicked due to mismatching SteamID

• Fixed a crash to do with env_projected_texture's texture

• Fixed some security issues reported on HackerOne

• Remove unnecessary return value in WorldPickerMouseDisable hook so GM:VGUIMousePressAllowed hook works more reliably for addons (Community Contribution)

• Fixed Lua error with creator tool when trying to spawn NPCs that do not exist on the server (Community Contribution)

• Blocked .vdf and specific .cfg files from being accessible by the Lua file library

• Added one more known Lua backdoor URL to HTTP blacklist

• Increased default value of mem_max_heapsize to 512, and block it from being changed by Lua API

• Block datacachesize convar from being changed by Lua API, to prevent crashes when set to invalid values

• Fixed monitor (and potentially other) materials in Hammer acting strangely when using "Fit" option in texture application tool.

The entire change list can also be found on our website: https://gmod.facepunch.com/news/may-2025-patch

Edit: For people still experiencing crashes when pressing "Start Game" - delete your bin/ and garrysmod/bin/ folders and verify game cache integrity through Steam. Some 3rd party files/programs that may have been put into the game's folder by the player are causing issues, such as graphics modifications. Updating those files might also work.

The March 2025 Update is now live.

Update Highlights

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.

You can find the full change list for this update in our blog post: https://gmod.facepunch.com/blog/october-2024-update

Hello everyone,

We are releasing a small patch today with some fixes for issues introduced in the previous update, as well as some bonus fixes.

Servers and clients are recommended to update as soon as possible.

The changelog is as follows:

• Fixed performance degradation with lots of static props
• Fixed crash with threaded addon file access
• Fixed changelevel crash to do with ragdolls
• Fixed crashes when trying to draw invalid sprite textures
• Fixed Lua errors when spawnlists contain invalid data
• Fixed spawning Sky editor not loading in Star Scale setting

Update Highlights

The Faceposer tool got some upgrades with this update, the model flexes can now be grouped into convenient, collapsible groups, making it easier to find what you are looking for at a glance.

These groups are loaded from the models themselves, so the support for this feature is up to model makers.

This update also comes with reworked default spawnlists, finally exposing every single model that comes with the base game, as well as pre-generated spawnicons for every single one.

Please note that these new spawnlists may not appear for you until you delete existing spawnlists (garrysmod/settings/spawnlists/ folder) if you played Sandbox prior to this update.

Be aware that this folder also includes your custom and modified spawnlists.

In addition to the new default spawnlists, you can now more easily create custom spawnlists for your addons. Simply right click on an addon in your Spawnmenu's browse section and select "Create a spawnlist from this folder". It will generate a spawnlist and group addon props by folder they are in. This also works for mountable games in the same section of the spawnmenu. Don't forget to save your changes when you add new spawnlists or modify them!

Other spawnmenu improvements include more information about weapons and entities straight from the spawnmenu, as well as a visual indicator when a tool is disabled by the server. (toolmode_allow_ console variables)

Finally, there are many, many smaller changes, a lot of crash fixes and many improvements for mod makers, as per usual.

The March 2024 Update is now live.

New Crosshairs

This update brings a new default crosshair for the base game, as well as ability to customize your crosshair.

This is usually fulfilled by using addons, but the default crosshair had a long standing issue of being impossible to see on bright backgrounds, so a new one was well overdue.

You can now customize the crosshair in the Options menu:

(You can reset the slider values by middle mouse clicking on them! It works in many places!)

The new default crosshair, a dot image, is visible no matter what you are looking at. You can still use the old crosshair if you really must, via the aforementioned crosshair customization.

The options menu was also changed a bit:

Bringing some of the more obscure settings to the front, so players know of their existence.

Sandbox Improvements

A quality of life change to the built-in Bodygroup & Skin changer is added in Sandbox:

You can now switch skins and bodygroups without closing the menu by right clicking on the options.

Additionally, new quick options are now available in the Server section of the menu bar:

These are only available to be changed in singleplayer or by the listen server host, but hopefully will bring more of a spotlight to existence of these settings.

A lot of more of them can be found in the Spawnmenu's Utilities tab, which were added in previous updates.

Portal 1 entities are now also available in the base game for owners of Portal 1 on Steam:

Other Changes

There has been a huge amount of other, smaller changes that may or may not be visible to players.

You can now share addon presets with your friends, or import them from collections:

Some improvements were made to duplicator support, such as saving NPC health and max health, "Make Persistent" option, and "frozen by physics gun" status.

A large amount of crash issues were fixed.

As usual, a large amount of new Lua API features were added for mod makers, as well as some minor improvements to map making tools.

The June 2023 Update is now live.

This update adds a few new visual effects for mappers and modellers to take advantage of, for better visuals.

There are also new additions for the Hammer Editor for mappers to enjoy, such as new entities, static prop lightmaps, and more.

We are also introducing experimental changes that remove the script limit for singleplayer, so that you can play with all your addons regardless of how many you have installed.

This update also adds a new option to delete temporary server files on game shutdown, such as sprays. This feature is controlled by gmod_delete_temp_files console variable and is enabled by default. If you wish to disable this feature, you can set the console variable to 0.

And as usual, there are plethora of new Lua API additions and changes for modders to create even cooler addons.

You can find the full change list for this update in our blog post: https://gmod.facepunch.com/blog/june-2023-update

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

This means that for a certain amount 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.

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

Hey everyone,

We are releasing another small patch today.

Biggest change with this update is the addition of Steam's Chat Filtering feature to the default in-game chat.

This filter can be disabled in-game via a check box in the chat's Filters section:

The filter also obeys your Steam preferences for chat filtering as seen here:

The entire change log is as follows:

• Prisoner pod and chair vehicles now react to damage physically, driver takes explosion damage, calls GM:EntityTakeDamage hook

• Spawnmenu search now resets its model cache when addons/games are remounted

• Fixed GMODLUA_GetUserType leaking onto the Lua stack (this only affects binary modules and the type() function, when using custom userdata types)

• surface.DrawLine now uses floats not integers

• Fixed a stack overflow with DListView and columns inserted at specific positions

• Fixes a server crash with no collide constraint.

• Fixed DTextEntry's automatic line breaks causing an infinite loop hang with specially formatted text containing a lot of whitespace

• Potential fix for a crash within CFontTextureRegen

• Add OS specific errors to binary module loading errors

• Make it more clear that changing sbox_persist while in-game will cleanup the map

• "Stop Persisting" property will now also be hidden when persistence is disabled

• Do not clean up map when disabling persistence

• Fixed changing persistence in-game saving to the wrong file if the cvar changed too quickly within the 2 second timer

• Downgrade Steamworks SDK to 1.50 as the newer version was causing issues

• Fixed 2 server lag exploits with default properties

• Fixed "join game" not showing up in Steam for P2P games after a changelevel

• Added string = util.FilterText( input, context, player )

• Added TEXT_FILTER_ enums

• Added safeguards to DownloadUGC when Steam sends us a null SteamUGCQueryCompleted_t

• Disabling hoverballs now adjusts their mass so they are not abnormally heavy when disabled, improved duplicator support for the disabled state

As usual servers are recommended to update at earliest convenience, especially if they were affected by one or more issues mentioned above.

Update Summary

This update brings a new tab to the Problems section of the main menu: Permissions. This new section allows players to see permissions they granted to servers they play on, both temporary which reset after game shuts down and permanent, which save across game restarts.

The permissions tab displays detailed description of what each permission allows the server to do, and allows players to revoke granted permissions.

The purpose of the permission system to give control over certain scripting features to the player. Currently only 2 permissions are available - Voice chat and server connection. In the future we may put more features that can be abused behind permissions.

Duplicator tool can now store a list of Steam Workshop items that were used to create a duplication.

Players can see the list in the Duplicator tool's context menu and click on each button to open the Steam Workshop item and subscribe to it, allowing an easy way to make sure all necessary Steam Workshop content for a duplication is present. This only applies to newly created duplications.

Map saves now also have a similar feature, but limited only to the map the save was made on. It should now be much easier to install necessary map for a map save.

As usual this update adds a host of smaller features for modders, as well as fixes a bunch of crashes, security issues and other bugs. You can see the complete change list below.

You will find the full change list for this update in our blog post: https://gmod.facepunch.com/blog/december-2021-update
