We've seen the promo shots of the Steam controller and heard generally positive reactions from indie developers, but we haven't yet seen it in action. That changed today, with a demonstration video that shows the prototype being used to control games ranging from the generally console-friendly shooters to more PC-centric titles.
The demo opens with Portal 2 running in "Legacy Mode," so the controller is simply reacting like a keyboard and mouse. The demo moves on to Civilization 5, which assigns the left pad to the camera and the right pad to the mouse pointer, with bottom buttons serving as zoom functions. Counter-Strike: Global Offensive shows off a bit of precision shooting, and then Papers Please uses both pads to control the mouse movement for broad or precision motions. Finally, the video closes with a call for fans to request games they'd like to see demoed in future installments.
