Yesterday Microsoft revealed the new wired Xbox One controller for PC users, which will be priced at $59.95 and is due for release in November 2014.
The controller is basically the same as the one that comes with the Xbox One console, although it comes with a USB cable and battery pack. It can also be used with the Xbox One as a wired or wireless controller, just in case you need a second one.
There's no word on the controller being used wirelessly on PC yet, but the Xbox 360 version did have a USB dongle which allowed for wireless play, so perhaps Microsoft could bring that out at a later date.
It works with Windows 8 and 7, and you can take a look at the details of the controller on Microsoft's website.
