Most of our Android games support any USB or Bluetooth controller with standard HID button mappings. A typical HID controller supports left and right thumbsticks, left and right triggers, a D-Pad, and A/B/X/Y buttons.
Examples: Xbox 360 Wired Controller, Nyko PlayPad Pro, Moga Pro.
In addition, Riptide GP: Renegade allows for custom controller mapping so you can change the controller button assignments.
We cannot help with steering wheel controller compatibility.
