Valve announced on its new Linux blog that Steam, the Source game engine, and Left 4 Dead 2 (L4D2) are being ported to Ubuntu Linux. Additional Valve titles will be ported later, and based on the success of their efforts around Ubuntu, Valve will look at supporting other Linux distributions in the future.
The goal of the Steam client project is a fully-featured Steam client running on Ubuntu 12.04. We’ve made good progress this year and now have the Steam client running on Ubuntu with all major features available. We’re still giving attention and effort to minor features but it’s a good experience at the moment. In the near future, we will be setting up an internal beta focusing on the auto-update experience and compatibility testing.
Since the Steam client isn’t much without a game, we’re also porting L4D2 to Ubuntu. This tests the game-related features of the Steam client, in addition to L4D2 gameplay on Ubuntu. Over the last few months, excellent progress has been made on several fronts and it now runs natively on Ubuntu 12.04. We’re working hard to improve the performance and have made good progress (more on that in a future post). Our goal is to have L4D2 performing under Linux as well as it performs under Windows.
