According to Kotaku, the game will feature "eight new 'theme park' levels and new game modes, including Ring Master, 'a series of slalom-style challenges with progressive difficulties' and the Gauntlet, 'an explosive new take on time trial'." The game will also support four-player, splitscreen play.
