Steam for Linux has been teased, tested, and is now ready for everyone to enjoy. In celebration of their official release to the Ubuntu Software Center, Valve is ripping the beta tag off of Steam for Linux and having a big sale to celebrate.Gaming on Linux has never gotten the attention it should, mostly because it’s considered too small of a market for developers to focus on. There’s certainly no technical reason, since most anyone who has bothered to make a game for Linux has found that even under identical specs the software will run circles around its Windows counterpart. Still, if there’s one thing you can count on in the mainstream gaming community, it’s that Linux users will be treated like their money isn’t worth collecting.Valve’s announcement that they would be giving the Linux community some love with a Steam client of their very own has been the cause of much celebration over the last few months, and today the Steam for Linux client can be found in the official Ubuntu Software Center.To celebrate the official release of the Steam for Linux client, you’ll be able to get your hands on 50-75% off sales on every game in the store that is available for Linux. Some of the games on the long list include Amnesia: The Dark Descent, Dungeons of Dredmor, Postal 2 Complete, Team Fortress 2, Trine 2, Counter-Strike: Source, Sword and Sworcery, Waveform, World of Goo, Frozen Synapse, Half-Life, and FTL: Faster Than Light.Additionally, Team Fortress 2 players will get a Tux penguin item in game when they sign into the game in Ubuntu.Canonical urges users to give Steam a shot in Ubuntu, especially in Big Picture mode while connected to a television.It has been suggested on several occasions that Steam for Linux and Big Picture are a pair of steps along the way towards the all important SteamBox that has been rumored for so long. A small Linux box running Steam in Big Picture mode and a nice controller would certainly be a worthy contender in the living room, especially now that there’s a place for game developers to give Linux users some love.
