Each console has its own set of controller(s) - Xbox comes with a controller for each console, such as the Xbox One controller, or the Xbox Elite controller if you're after a little more control. Then comes along the PlayStation 4 with its DUALSHOCK controllers, and then the Nintendo Switch with its Nintendo Switch Pro Controller and Joy-Con controllers. But, what happens when you've only got an Xbox One controller but would like to play on another console? Well, you'll either be relying on having a spare controller for the other console lying around somewhere, or having to buy a new controller. What if, instead, you could pick up the Xbox One controller, place an adapter on it, and begin playing on a console of your choice? That's what Brook Design, LLC, is aiming to do with its latest Kickstarter. Called the "X One Adapter", it allows users to place an adapter on the back of their Xbox One controller and enables the ability to use it with other consoles.
