==== OS X, Linux, and Android support ====
In April 2010, Valve released all of their major Source games on [[OS X]], coinciding with the release of the Steam client on the same platform. Valve announced that all their future games would be released simultaneously for Windows and Mac.<ref>{{cite web |url=http://store.steampowered.com/news/3569/ |title=Valve to Deliver Steam & Source on the Mac |publisher=Valve |date=March 8, 2010 |access-date=March 8, 2010 |url-status=live |archive-url=https://web.archive.org/web/20130826011221/http://store.steampowered.com/news/3569/ |archive-date=August 26, 2013}}</ref><ref>{{cite web |url=http://kotaku.com/5488375/left-4-dead-2-team-fortress-2-portal-and-steam-coming-to-mac-in-april |title=Left 4 Dead 2, Team Fortress 2, Portal and Steam Coming to Mac in April |publisher=Kotaku |date=March 8, 2010 |access-date=March 8, 2010 |url-status=live |archive-url=https://web.archive.org/web/20111218172810/http://kotaku.com/5488375/left-4-dead-2-team-fortress-2-portal-and-steam-coming-to-mac-in-april |archive-date=December 18, 2011}}</ref> The first of Valve's games to support Linux was ''[[Team Fortress 2]]'', the port released in October 2012 along with the closed beta of the Linux version of Steam. Both the OS X and Linux ports of the engine take advantage of [[OpenGL]] and are powered by [[Simple DirectMedia Layer]].<ref>{{Cite web |title=Simple DirectMedia Layer - Homepage |url=https://www.libsdl.org/ |access-date=April 21, 2015 |url-status=live |archive-url=https://web.archive.org/web/20180421220935/http://libsdl.org/ |archive-date=April 21, 2018 }}</ref> During the process of porting, Valve rearranged most of the games released up to ''The Orange Box'' into separate, but parallel "singleplayer" and "multiplayer" branches. The game code to these branches was made public to mod developers in 2013, and they serve as the current stable release of Source designated for mods. Support for Valve's internal Steam Pipe distribution system as well as the [[Oculus Rift]] are included.<ref>{{Cite web |title=News - Source SDK 2013 Release |url=http://store.steampowered.com/news/10962/ |website=Steam |access-date=April 21, 2015 |url-status=live |archive-url=https://web.archive.org/web/20150408214515/http://store.steampowered.com/news/10962/ |archive-date=April 8, 2015 }}</ref> In May 2014, [[Nvidia]] released ports of ''Portal'' and ''Half-Life 2'' to their [[Tegra 4]]-based Android [[handheld game console]] [[Nvidia Shield]].<ref>{{cite web |url=http://blogs.nvidia.com/blog/2014/05/12/half-life-2-portal-shield/ |title=The Greatest PC Games of All-Time – 'Half-Life 2′ and 'Portal' – Now Available on SHIELD |publisher=Nvidia |date=May 12, 2014 |access-date=May 12, 2014 |url-status=live |archive-url=http://archive.wikiwix.com/cache/20140513215833/http://blogs.nvidia.com/blog/2014/05/12/half-life-2-portal-shield/ |archive-date=May 13, 2014}}</ref>
