The Steam for Linux Beta client supports the free-to-play game Team Fortress 2. Approximately two dozen additional Steam titles are now also available for play on Linux systems. Additionally, the Steam for Linux Beta client includes Big Picture, the mode of Steam designed for use with a TV and controller, also currently in beta.

“This is a huge milestone in the development of PC gaming,” according to Gabe Newell, Valve President and co-founder. “Steam users have been asking us to support gaming on Linux. We’re happy to bring rich forms of entertainment and our community of users to this open, customer-friendly platform.”

The Steam for Linux Beta client is currently available for installation on Ubuntu 12.04. “An overwhelming majority of beta applicants have reported they’re running the Ubuntu distro of Linux,” according to Frank Crockett, a member of the Steam for Linux team, “We intend to support additional popular distros in the future; we’ll prioritize development for these based on user feedback.”
