Garry's Mod
A sandbox game for the PC, Mac and Linux

Garry's Mod is a Sandbox Game based around the idea of building. Unlike most other games there aren't any objectives - you can't lose and you definitely can't win.

December 2015 Update

👤 🕔 December 16, 2015 116

An update has been released!

This update includes a lot of exploit, crash and Half-Life 2 campaign fixes, as well as other minor bug fixes and Lua API improvements.

Thanks to the following people for helping us out and reporting dangerous exploits:
Willox, Leystryku, Python1320, MeepDarknessM/Meepen and ogniK.
And thanks to everyone who helped testing the update and reported bugs/problems.

As usual, servers will need to be restarted.
The update will be automatically downloaded when you restart your game.

      I was trying to let my brother play GMOD with LAN Server, it said “Connecting to Server” and showed only 3 bars. It’s been 3 hours and still nothing! Please help!

      Wow this is great did you fix any problems with any NPC not shooting RPG’s?

    Honestly,I am waiting for supporting Portal 2 and Left 4 Dead 2 maps,especially CS:GO as well maybe?
    I know those are running in different engine,but it will be very disappointing,if in the far future Source 2.0 will be mostly used and releasing most games,so Garry’s Mod won’t be necessary anymore.
    Please try to support those maps if possible,community does get them,but still giving major errors inside the maps already.

      It’s probably not going to happen, Unless Valve decides to port games you mentioned to Source 2. Actually the better question is that if Garry’s Mod
      gets ported to source 2 (If it does.)

      Every one this happens to every (mostly) antivirus (even to me) but you should all know is gmod has been around for years and is a very big game I and ValvE promise that gmod is a safe game… Also gbombs can mess with the game. As it is broken and unstable right now.

    • Johnny

    It’s definitely pleasing to see that GMod development is almost entirely focused on fixing bugs and not adding unnecessary new things that could most probably further destabilize the game

    • Bimo
      December 17, 2015 at 12:41 am

      Yeah its a big issue in this new update. It deleted peoples hl2.exe file so you are unable to start gmod till they fix it.

    • Brady
      December 26, 2015 at 6:12 pm

      It’s because your anti virus deletes hl2.exe because it’s a turd and mistakes it as a virus

      Well you should disable for a few minutes or whatever. Also it’s clearly a piece of crap if it doesn’t let you download anything and calls anything that is an execution file (.exe) a virus then you should use something like AVG, MalawareBytes something nicer than what you currently have.

    Another bug to add to the long list of them introduced in this update. My hud disappears and a have to leave the server to fix. Happens often.

    • Brady
      December 26, 2015 at 6:53 pm

      Try typing record fix into console then typing stop. It should fix your hud. If you don’t know to enable the developer console press options go to advanced options and check it then press the lil’ squiggly button under the esc key and type it in. Also if you needed it when on the main menu hold it for a few seconds and it was pop up. You can also press the key again and it closes the console.
