According to our friends at ONM, the game will allow players to shoot, pass, tackle and adjust tactics using Nintendo's tablet controller.
You can take control of different players by tapping them on the GamePad's touchscreen. Tapping on an attacking opponent will then allow you to either man mark or tackle them.
In addition to defending and passing using the tablet, shaking the controller or pressing L3 brings up an image of the goal which you can tap on to place shots.
You can also adjust tactics on the screen when playing as the manager, plus there's a new GamePad-based free kick and penalty system. Get all the details over at ONM.
Does the GamePad sound like something you'd use for FIFA 13, or would you rather play with the Wii U Pro Controller?
