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.


Welcome to Steam Pipe


The switch has been made. We’re now on Steam Pipe. So here’s some things to review – because I know people have probably not read anything about converting to Steam Pipe before they had to.


For server owners:


For players:

If GMod is failing to launch:

  1. Right click on Garry’s Mod in Steam
  2. Go to properties
  3. Click on “Local Files”
  4. Click on “Verify Integrity Of Game Cache”

Steampipe Switchover


We’re switching over to Steam Pipe. Here’s what that means for you.


If you run a server

If you run a server then the way you download and update the server is going to change. The old way won’t work anymore.

The new way is described here. There’s also plenty of detail on Valve’s wiki.


If you play Garry’s Mod

For the player the initial switchover will be the hardest part. Any addons you have manually installed might not get carried over – so you might want to back up your Garry’s Mod folder before making the switch.

You will get some benefits though. Load times should be vastly reduced. Updates will be more frequent. There will be a development branch that you can opt into to receive bleeding edge updates. You’ll be able to choose which hard drive you want to install onto.


If you mod Garry’s Mod

Modding will be a bit easier in the new system. All of the files are extracted to disk instead of being in a gcf. This means you can easily browse the files to see how stuff is done.

The development branch will be better for modders – because requests can be added instantly. Your addon or gamemode can be tested with the development branch and problems can be found before we ship the update to the release branch.

Ode To Garry’s Mod


Every wonder what would it would be like if HL2 and Garry’s Mod were real and everyone stopped phoning Dr Kleiner and he got sad?


Well – a bit like this I suppose?


2 Million Copies Sold!


Some time over Christmas we surpassed the magic number and as of writing Garry’s Mod has sold 2,082,813 copies worldwide!

One word. Whoa. This is amazing when you consider that selling nearly 6,000 copies on launch blew all my expectations out of the water!

For those keeping tabs, GMod has existed for 8 years. It’s been on sale for 6 years. It had sold 1 million copies by July 2011. The average time played is 89 hours and 24 minutes, the average play session is 42 minutes long.

We’re 8 today!


It was eight years ago today that I released the first version of Garry’s Mod!

The first ever version was made in a few hours – and contained only the ability to create ropes between physics objects – using a crossbow. It was originally released in a thread on Something Awful. Version 2 was released a few days later (I had a hatred of decimal versions).

If you are interested – you can read more in the history section.

6 Years


Six years ago today, Garry’s Mod 10 went up for sale.

On the 29th November 2006 it sold 5,700 copies. This was a huge huge number at the time, I could not believe it could possibly sell that much. When it first went on sale it actually knocked Steam offline temporarily. A few weeks later it was selling around 300 copies a day. In that first year it sold 147,666 copies. Wow!

Six years and 153 updates later it’s averaging about 1,200 sales a day.. and on the 22nd of November it sold 38,511 copies. In the last year it sold 716,632 copies!

I scratch my head now – because 5,700 copies doesn’t seem like that much. But it must have been a lot back then – because Valve sent me a hat made out of actual money to celebrate (for the record it was made out 700 GBP).

Happy Birthday Garry’s Mod!

Status Report


Apart from a few shocked people, things seem to have gone quite smoothly.. especially considering the amount of things that could have gone wrong. The workshop seems to be filling up nicely, there haven’t been any massive problems. Except these.

The server browser was showing servers from the old version. This has led to a lot of confusion. This should be fixed in a patch going out shortly.

The open workshop button was opening the beta workshop. That was also leading to a lot of confusion. That should be fixed in a patch going out shortly.

Settings weren’t staying saved. That should be fixed in the patch. And language wasn’t #loading. That should be #fixed.

The remaining huge problem right now is that XP users are freezing on map load. I’m on it, I’m building an XP machine to run tests on. In the meantime if anyone has any additional information about it – please let me know on As far as I know everyone with Windows XP SP3 is freezing, if you know any different, let me know.

In the meantime, for those who can try to this addon:

Today’s the day!


Just a warning, you might notice some weird stuff happening with GMod today. This is because I need to update the steam app configuration with the new achievements and workshop stuff. If something goes wrong today just assume it’s because of the update and that it will be fixed soon.

The update itself will be like any other GMod update. I’ll package it up and send it to Valve around 4PM GMT. Valve usually update it within an couple of hours. There won’t be any great fanfare or price drops – this week is about getting it stable and putting out any fires.

Once the update is released I’ll put out the new workshopper tool that will allow modders to upload addons to the live Garry’s Mod workshop. None of the content created for the beta will carry over – modders will need to re-upload everything they’ve made.

Then I’ll be watching the support system, and the forums, and the Steam discussions stuff for any problems. Then depending on the severity of those problems we’ll either see an update tomorrow or Friday.

Sound good to ya’ll?

1 Day Remaining!


So.. you have one day remaining until GMod 13 overwrites GMod 12. You should start thinking about backing up your Garry’s Mod folder – in case you have any maps or whatever you want to keep. They probably won’t get removed – they will probably just carry over like any other patch – but it’s better to be safe than sorry.

If you want the cleanest possible transition into GMod 13 then it would be a good idea to give your Garry’s Mod folder a total cleanup.

It’s today we say goodbye to Toybox. Bye Toybox! Toybox was great, it served it’s purpose.. now we have workshop! If you had maps or models or something on Toybox and want to keep it – I uploaded a huge torrent with all the content in to the internet for safe keeping (please don’t extract 36gb into your garry’s mod folder! And if you do – please don’t ask for support!)

See you tomorrow guys!

One Week Remaining


Ok guys, it’s getting serious now. We have one week until Garry’s Mod 13 will swallow Garry’s Mod 12. Here’s some stuff to keep in mind:

  • GMod 12 Saves and Demos will probably break!
  • GMod 12 Addons and Gamemodes probably won’t work – seek replacements on the Workshop or bug the original author!
  • GMod isn’t ever done – we’ll be at work right after the patch to fix any inevitable problems.

Gamemode Coding Contest


The Gamemode Coding Contest is back! The latest instalment is starting over on the forums. The contest theme this time around is Rhythm (which I can’t spell).

Grea$eMonkey says there’s no real prizes this time.. but I’ll try to talk him out of it. He’s also set up a website for the contest here – so get coding!

Playable Piano


In preparation for the comeback of GMTower – MacDGuy has released a playable piano on Workshop for Garry’s Mod 13. It works in multiplayer and comes complete with sheet music!

Check out my m4d l33t piano skills!

Head over to workshop to subscribe! (You need to be in the GMod 13 beta and be signed in).

Lua Rollercoasters Addon


Foohy has finally released his awesome rollercoaster addon!

It only works on the Garry’s Mod 13 beta and is available on the workshop (You need to be logged in to see/subscribe).

If you’re new to the workshop just go to that page – click subscribe – then next time you’re in GMod13 it will automatically download and install the addon. Don’t forget to give it a thumbs up!

You can find out more about it, report bugs and ask questions in the official thread right here.



Garry’s Mod isn’t the easiest game in the world to use. And I an only imagine how much harder not speaking English would make that. So in GMod 13 I’m trying to fix that.

We’ve set up a translation site with crowdin which is coming along nicely – thanks to all those people that have contributed so far. We are suffering on Chinese, Japanese and a few others – so if you speak any of these languages and feel like helping the community out – please get involved.

If you have already contributed please check it periodically because I’m adding new phrases almost every day.
