Microsoft will launch a new controller designed for players with limited mobility later this year.

The Xbox Adaptive Controller, which will be compatible with Windows 10, comes with two large, central buttons plus a number of attachment slots on the top, each of which corresponds to a button on the standard Xbox controller. You'll be able to plug other buttons, joysticks, foot pads, and supported third-party controllers into those slots, essentially creating your own custom control scheme that you can remap whenever you want.
