Valve has announced a Steam sale simply titled ”STEAMOS SALE” with interesting games that are already available and games that they claim are heading over to the platform. The list seems to include some quite big titles too!A big part of the games featured on the sale are titles that are already on Linux, such as the Aspyr ports Borderlands 2 and Civilization V and indies like Ziggurat and Kerbal Space Program, but as much as we love those games the announcement has something even bigger. Games that apparently are getting ported but have so far been unannounced. Torchlight II is now officially available, so go check it out. It seems they waited for this big announcement to make a real splash!Now, before I set out to list these games, I'd like to remind all of you not to blindly buy the games mentioned. I know, I know, it seems very official and all, but we haven't heard anything from some of these titles, so be careful. We are trying to reach out to everyone we know for confirmation.However, they have massive "Coming to SteamOS" banners on the Steam homepage, so it's extremely exciting.Okay, now that we have the disclaimers out of the way it's time to blow your minds.The sales page promises titles such as- Shadow of Mordor- Payday 2- Batman: Arkham Knight- Saints Row IV- Company of Heroes 2- Magicka 2- Total War: Rome II- The Witcher III- GRID Autosport- Total War: Attila- Evolve - (listed here: http://store.steampowered.com/universe/games/)All will be heading to SteamOS/Linux.is officially confirmed, and is being ported by Feral Interactive. Feral have stated to us officially that it will release “this spring”, and they have publicly announced it on twitter now too:is fully official now too:andare also official, and they have updated their store pages to say this:have updated their store page availability to state this:- Already has a Linux icon, possibly not a same-day release even though it has a Linux icon, as the store notes it will be released on SteamOS in the "fall" which is after the release. So, not sure why it has a Linux icon now.- The only one not mentioning anything about SteamOS/Linux on their store page.Source: http://store.steampowered.com/sale/steamos_saleThis is exactly the type of support and push we needed to see, and I'm extremely happy it's happening! I'm trying to remain coherent amongst this utter nuke of news.Begin going nuts. Now where's my wallet?
