Valve has officially revealed that it plans to bring its Steam game distribution service to the Linux platform. The company is also working to port its Source game engine and its popular 2009 title Left 4 Dead 2 (L4D2). The Steam port for Linux was announced this evening on the Valve website in a new blog that will chronicle the progress of the company’s Linux development efforts. Valve says that it is currently working to refine the software, but declined to say when users can expect to see it launch. The company is optimizing L4D2 to ensure a suitably high frame rate. They are also porting other undisclosed Valve titles and putting the finishing touches on the Linux version of the Steam client. Read the full story at ARS Technica.
