Ever since Valve revealed the Steam Controller, I've been anxious to see it in action. Well, Valve has finally released a video of someone using it.
The video shows off both the FPS usage and mouse usage of the controller. Portal 2 and Counterstrike display it's usage in games that a mouse and keyboard are the preferred choice. The controller looks like it holds up pretty well though.
Civilization 5 and Papers Please show off the mouse mode and here it looks like the controller works quite well.
We won't know until we can get our hands on one if the controller is really good and easy to use, but the video shows it does have the potential.
