The sale lasts until February 21 and takes 50 to 75 percent off the 54 games Linux users can slot into their brand new platform. Team Fortress 2 joins the revelry by automatically awarding a free and tradeable in-game Tux accessory for all Linux mercs jumping into the free-to-play shooter before May 1.
