I ever tell you about the time my buddy Keith played L4D2 on Linux?

The L4D2 Beta is mutating. Not content to just be the testing ground for the new Extended Mutation System , we will be adding Linux to the Beta. And not content with the number of testers in the Beta, we will also be opening up the Beta to all L4D2 owners. Huh, what? The L4D2 Beta build is a separate download from the main game. This is where we are testing new features to the game – currently we are testing EMS . Starting next week, we will be testing Linux there as well. This code churns more frequently than the main game depot, so if you are bandwidth constrained, you might want to wait for the changes to move to the main game. If you are playing the Beta game, you can only connect to other players in the Beta and to Beta servers. Next week it will appear in your library alongside the main L4D2 game. You do not need to enter a code to gain access and it is totally voluntary to download and participate in the Beta. For modders currently in the Beta, now would be a good time to update your current work and get ready for a whole bunch of new testers. For players, not only is the Linux build new, but the Window and Mac versions are also updated, so we need plenty of non-Linux testing as well. When the Beta expands next week, we will post on how you can help give feedback and participate in the Beta.
