What’s that Beta thing again?

We have had plenty of people asking about the L4D2 Beta showing up in their steam catalog. So in case you missed it or were confused, here is some more info.

Currently, changes to L4D2 will first appear in the Beta before they appear in the main game. The Beta will change often. This mean this build is very active so you might want to avoid it if you have bandwidth caps. Today we released another update for it. You can read the release notes for the update here.

Right now the Beta is the only place you can play L4D2 on Linux natively. If you run Linux, load it up and give it a try. If you have problems, let us know. You can post here and share your experience.

While the biggest changes are for Linux, those changes actually have the possibility to impact Mac and Windows players as well, which is why it is helpful for even non-linux players to test the Beta.

The Beta also contains an update to the Authoring Tools to allow you to work in the new EMS. These tools are only available for Windows users and only currently available in the Beta. You can check the developer wiki here for more information.

While the tools are only available on Windows, everyone in the Beta can play the new EMS content.

We do not have servers running for the Beta yet as we concentrate on client issues and fixes but the server code has been released and is working - so let us know if you have any issues with Windows or Linux servers. We will be rolling out our own dedicated servers in the near future.

The Linux Beta Build is Live!

Thanks to the efficiencies we were able to achieve with Linux, we skipped Valve time and are delivering the L4D2 Beta Linux build today as planned. The Beta build not only allows Linux owners to play the game natively, it is also the testing ground for our new Extended Mutation System.

If you currently own Left 4 Dead 2, You should see “Left 4 Dead 2 Beta” in your library. If it doesn’t show up, restart Steam. This is a complete build of Left 4 Dead 2, so the build is as large as the current game.

You also receive access to the Left 4 Dead 2 Beta Authoring tools and Left 4 Dead 2 Beta Dedicated Server. This will allow you to start working with EMS.

The Beta version also contains updated Windows and Mac clients, so even if you are not running under Linux you can help by testing the Beta.

Current changes in this build include:
- Server operators can now specify whether or not custom content is allowed when playing on their servers. This can be set on a per game mode basis - see cfg/addonconfig.cfg for details.

- Fixed main menu not refreshing after workshop add-ons have been loaded. Custom UI skins should display correctly now.

- Reworked add-on management to improve stability and properly support custom mutations

- Prevent an intermittant crash when browsing the add-ons screen

To give us feedback on the Beta, please use this brand new forum.

If you aren’t up for downloading the beta, we are trying a new experiment with our friends over at Pinion. On the additional official servers they are hosting, we have added four new community campaigns to them so that you can get the stock L4D2 experience on some great community maps. It was tough work playing so many great custom campaigns as we narrowed it down to four. To quote Daniel from Pinion, "Diescraper has some of the best levels I've played in L4D2!!". Yes it does… And with campaigns only a mouse click away thanks to the Workshop, make sure to give them a try this weekend.

Here are the current list of supported Campaigns.
