Asus' ROG Phone 8 is being marketed as the next big gaming smartphone, but to reach those heights, you naturally need a good controller to support it, and according to an exclusive leak provided to windowsreport.com, the ROG Tessen Mobile controller is just such a product.

The controller will feature two analog sticks as well as a D-pad and a four-button layout.
