Today is a big day for Linux Gaming. Developer Valve made an announcement on their blog
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.
Over 60.000 linux users registered at the Valve survey but only a select group received an official invitation.
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.”

You may download the steam.deb (~2mb) at their website. However it requires a verified beta-account to use the software!
