Xbox Wireless Controller works with Shadowgun, Riptide, GTA and Death Trigger.
Just plug-in the wireless receiver into the dock, and push the xbox symbol on the controller.
After a while, the blinking changes, and you can use the controller.
Badly, it doesn't stop blinking alike when you connect it to a PC or an Xbox.
I also was able to connect PS3 controllers to the Infinity via sixaxis, the controller also worked with all the games i wrote î.
