 The Wii U version supports both co @-@ operative multiplayer , in which a second player can control a remote controlled vehicle to assist Sonic , and competitive multiplayer , in which a second player can use the Wii U Gamepad screen to race against the other player . The game also supports Miiverse and Off @-@ TV Play functionality . Using Miiverse , players can exchange items such as Wisps or shields , which grow more effective if they are used by other players . The 3DS version supports both local and online multiplayer for up to four players . Players may also customise RC vehicles in the 3DS version , which can then be used in the Wii U version .
