Images of Razer 'Kazuyo' Game Controller Leaked
The enclosure controller, reportedly named the Razer Kazuyo, appears to wrap around the iPhone, adding face buttons, shoulder buttons, and a directional pad on either side of the phone. This layout is similar to other iOS game controllers such as the Logitech Powershell and the MOGA Ace Power, which were both released in last month. Unlike both controllers however, the Razer Kazuyo includes the ability to tilt the iPhone up, allowing for better viewing angles and easier access.
It is not known when exactly the Razer Kazuyo will be released, but it is likely that it will be compatible with a growing list of iOS games upon availability. Currently, games such as Dead Trigger 2, Asphalt 8: Airborne, and Bastion offer controller support, with additional developers pledging to build controller support into their apps now that controller hardware is available to consumers.
