- Younger and less-experienced players will love playing as Toadette, who is brand new to both games, and Nabbit, who was formerly only playable in New Super Luigi U. Both characters offer extra assistance during play.
- Multiplayer sessions are even more fun, frantic, and exciting thanks to entertaining character interactions. Need a boost? Try jumping off a teammate’s head or getting a teammate to throw you.
- Features a wealth of help features, like a Hints gallery, reference videos, and a Super Guide in New Super Mario Bros. U that can complete levels for you if they’re giving you trouble.
- Three additional modes—Boost Rush, Challenges, and Coin Battle—mix up gameplay and add replayability, while also upping the difficulty for players who want to try something harder. Players can use their Mii characters in these modes.
