With today’s update, we fixed an issue with dedicated servers and workshop content. This should resolve some of the consistency issues people are seeing while playing on a dedicated server.

Server operators will need to move workshop content from addons to addons/workshop for it to work correctly – sorry about that.

To celebrate, we are adding Helm’s Deep Reborn to our own official servers. Gone is the long explanation of how to download and install the campaign. Now – just <a href="http://steamcommunity.com/sharedfiles/filedetails/?id=121068229">visit its workshop page</a> and click subscribe. Next time you open Left 4 Dead 2 it will begin to download. If the campaign gets updated – it updates automatically for you. It’s that easy.

Make sure to choose official servers when you play to join one of our servers. It is a survival only campaign, so it is not playable in other modes and you need to make sure it has finished downloading to play it.

We are also continuing to work on the Extended Mutation System in the <a href="http://steamcommunity.com/groups/L4D2WSVB">L4D2 Beta</a> with an ever widening group of modders pushing gameplay into new and old places. We just released a new example mutation that allows you to play L4D1 style inside of L4D2! We are working with the content creators and adding features before we release this new tool and its many creations onto the world – stay tuned.

Today we are releasing an Expanded Mutation System for the <a href='http://steamcommunity.com/groups/L4D2WSVB'>L4D2 Beta program</a>. Modders from around the world will help us test the expanded tools before we roll them into the main game and the workshop.

What is EMS? It is vastly improved scripting system that allows script authors to go past modifying existing scripts and write custom script logic, spawn and control entities, and much much more.

Mod authors will now be able to create deep custom experiences that can be played on any map or tailor create something for new or existing maps.

We have included numerous examples including a new survival mode called Holdout, other all new game modes, and numerous other examples to help show mod authors how to use the new tools.

We have also included <a href="http://developer.valvesoftware.com/wiki/L4D2_EMS/Intro">a wiki</a> walking through some of the simplest examples and this week we will be online in the Beta group chat and forums to help modders learn the new tools.

How long will EMS be in beta? Long enough for us to achieve our goals:
- Find out what new tools people use, and how well they work.
- Find out what are the most important missing features we can add.
- Drive out as many bugs and issues as possible.

For everyone else waiting to play these new creations, we have some changes coming up for the workshop and our servers based on community feedback.

*The screenshots with this post are from the example game modes shipped with the beta.

Thanks to <a href='http://steamcommunity.com/workshop/browse/?appid=550'>the Workshop</a>, Left 4 Dead 2 continues to change.

Mod authors continue to add content to the Workshop, so keep coming back and checking to see what’s new. You can download the Workshop items automatically by clicking subscribe. This will also keep that item automatically up to date!

If you don’t see the add-on choice on the main menu – remove any hud or UI addons you are currently running; they may not have changed for the new layout. If you are downloading a campaign, make sure to check to see if it is in a collection which requires you to download all the elements in that collection. A good example is for Warcelona you need to go to <a href='http://steamcommunity.com/sharedfiles/filedetails/?id=121787087'>this page</a> and download all three parts.

We have currently removed all community created campaigns from our official servers as the authors move them to the Workshop. We will be restoring them with the new versions and featuring new Campaigns starting next week. We have the first few lined up and then will begin taking suggestions from the community.

Remember, you can also rate items in the Workshop and join us in <a href='http://steamcommunity.com/workshop/discussions/?appid=550'>discussing the Workshop</a> and letting us know what you would like to see.

Based on feedback from community, we have increased Mod Author’s cloud storage in the Left 4 Dead 2 Authoring tools to 2gb! A quick tip – if you are creating character packs, make sure to offer the individual characters as well so players can mix the packs together. <A href='http://steamcommunity.com/sharedfiles/filedetails/?id=121286119'>Formal Coach</a> needs to hang with some <A href='http://steamcommunity.com/sharedfiles/filedetails/?id=121288011'>Velociraptors</a>.

Lastly and most importantly, today we are updating the Mac client for L4D2 to resolve issues Mac players are seeing with the Workshop. If you are on a Mac, it’s time to join in the fun and start grabbing some great skins, campaigns, and more.

We are working on the Mac Client issue this morning and investigating reports of Window server crashes.

A few notes.
If you are trying a campaign in any gamemode and having issues connecting to a dedicated server, try to play locally. If it works locally, contact your server operator and ask them to update.

We will be removing all of the community campaigns we host on our servers and refresh them with the versions on the Workshop as they become available.

DO NOT UPLOAD CONTENT TO THE WORKSHOP THAT IS NOT YOURS!
If you do, the content will be removed and you will get a temporary community ban.

Please use the reporting tool to report any upload violating the Steam Terms of Service. You do not need to report how much that mod kicks ass.

thanks

Today we are moving the Left 4 Dead 2 Workshop out of beta! So right now with a click of a button, you can add campaigns, items, clothing, weapons and more.

Content creators have been hard at work creating content for L4D2 but they have just gotten access to the new Workshop, so give them some time to upload their work.

To help other players find the coolest content, make sure to rate and discuss the submissions. We will be featuring submissions on l4d.com

To add content to L4D2:
Load up Left 4 Dead 2 (or browse to it here). In game, click on the add-ons section from the main menu. There you can see add-ons once they are downloaded or choose browse the Workshop. Go into the Workshop, find a something you like – let’s say a skin for Francis where he is in a cop outfit. Click the subscribe button and it will automatically download and appear in the list. If you are doing this through the web browser, it will appear next time you start the game.

Please note – the Workshop has increased its file size limit to 200MB. But this still means some of the larger campaigns will be broken up into sub-200mb chunks. Those campaigns will be in collections and you will need to subscribe to the collection to get all the files.

To create and share content in L4D2:
You will need to update your Authoring Tools and run the Workshop Manager in the tools to upload your content to the Workshop.

A great tip from GShock:
If your campaign is over 200MB you will need to split your vpk into parts with content in each part.

This will also allow you to update your content a lot faster and in turn users do not have to download a much larger file when you release an update to a part.

*Example:
Part 1 Sounds and Scripts
Part 2 Map 1
Part 3 Map 2
Part 4 Materials
Part 5 Models
*Include your missions folder in each part along with your addoninfo.txt file

Once this is done add all your items into a collection and mark it as a "items that work together (will show a 'subscribe to all' button)"

For both consumers and developers, there is a new forum – the Workshop discussion forum. Here you can discuss using the Workshop and report any bugs you are encountering. Each item in the Workshop has its own area to discuss that item.
