DualShock 4 Somewhat Compatible With PlayStation 3

YouTube user Udetto decided to see if the PlayStation 4 controller, the DualShock 4, would be compatible with the previous console. He tried it out on camera with Urban Trial Freestyle and found the controller to work perfectly.
He was able to navigate the levels no problem and it was responsive to all buttons and combinations. However, it seem FIFA 14 wasn’t working as well. The menus were fine, but it was really iffy on everything else.
However, it seems that it only worked with the controller was plugged in. Games that require the controller to be wireless or in wireless mode will not work.
