Mere days after unveiling a whopping 15 initial Steam Machines at this year’s Game Developers Conference, Valve’s Steam store is conducting a massive sale on Linux-based games compatible with the upcoming SteamOS.

More than 50 titles are highlighted, including three of PCWorld’s favorite games of 2014—The Talos Principle, Transistor, and our Game of the Year, Wasteland 2—and a slew of other spectacular titles like Metro Redux, The Witcher 2: Assassin of Kings, Borderlands: The Pre-Sequel, Civilization: Beyond Earth, XCOM: Enemy Unknown, and Goat Simulator, among many others.

While a couple of the games are at or near full retail price (like Dying Light and upcoming titles such as The Witcher 3 and Hotline Miami 2), the vast majority are being offered at deep, Steam Sale-esque prices. Pay careful attention to those system requirements, though—despite this being billed as a SteamOS sale, some of the games are only compatible with Windows at the moment. (PSA: Virtually all of the Linux/SteamOS titles also offer Windows counterparts, as well.)

Beyond the aforementioned trio of our Game of the Year favorites, PCWorld’s spotlight on 25 killer Linux games can help you figure out which of the games are worth your hard-earned cash. The deals last through Monday, March 9.
