Valve today announced the release of its Steam for Linux client. The Steam client is now available to download for free from the Ubuntu Software Center. Ubuntu is the most popular distribution of Linux used by millions of people globally and known for its well-designed, easy-to-use customer experience.

"The introduction of Steam to Ubuntu demonstrates growing demand for open systems from gamers and game developers," said David Pitkin, Director of Consumer Applications at Canonical. "We expect a growing number of game developers to include Ubuntu among their target platforms. We’re looking forward to seeing AAA games developed with Ubuntu in mind as part of a multi-platform day and date release on Steam."

"We’re huge fans of Linux. It’s like the indie OS-a perfect home for our indie game," said Alen Ladavac, CTO of Croteam, creator of the Serious Sam franchise of games. "And who better to lead the charge into Linux gaming than Valve? With Steam distribution on Windows, Mac OS, and now Linux, plus the buy-once, play-anywhere promise of Steam Play, our games are available to everyone, regardless what type of computer they’re running. That’s huge."

Team Fortress 2, the Free to Play game, is also now available on Steam for Linux. For a limited time, Steam users who play the game on Linux will automatically receive a free, exclusive in-game item: Tux, the Linux mascot, can be carried by any of the game’s classes and traded between players. Additional Valve titles available on Steam for Linux include Half-Life, Counter-Strike 1.6, and Counter-Strike: Source.

In addition to games, the Steam for Linux client includes Big Picture, the new mode of Steam designed for use with a TV and game controller. With Steam for Linux and Big Picture mode, Valve anticipates a growing number of gamers will use Steam in the living room.
