An update has been released for Portal 2
Windows
— Fixed an issue where in-game audio caption language would use the system language setting instead of the Steam language setting.
Controller support
— Improved camera control through Steam Input – the sensitivity scale has changed so you may need to increase your configuration’s sensitivity.
— Add local coop support for one controller player and one Mouse/Keyboard player.
— Add local coop support from the community coop map queue. Quickplay is still not supported.
— Fix XInput related options being hidden when connecting a Steam Input enabled controller using a Gamepad configuration.
— Fix the challenge mode screen not having enough footer buttons available through Steam Input.
— Fix several more bugs where the incorrect action set could be set in Steam Input.
— Fix several cases where having a controller connected but not active would affect the glyphs and settings screen options.
