The new Apple TV is a much more capable device than its predecessor. It has a Siri remote that lets you interact with it with voice and touch. Since the device is powered by tvOS and runs apps, you can expect to play games on it. Nimbus is a handy controller that lets you play on your Apple TV more conveniently. It has pressure sensitive buttons, a menu button for faster navigation, and a Lightning connector.
Nimbus has a rechargeable battery that lasts up to 40 hours. The companion app gives you access to a list of controller-enabled games. More information is available on Steel Series.
