Mario Kart has gone through innumerable incarnations, and Nintendo Wii U's Mario Kart 8 is about to get even more fun. Nintendo is adding a slew of new features in its latest paid DLC Pack 2, including new race tracks, new bikes, and more. There's also a free software update for the game coming soon. Also incoming are nine additional amiibo figures like Sonic, Pac-Man, and Mega Man. Tapping the amiibo figure on the Wii U touchpad unlocks new Mii Racing Suits themed accordingly.
