Super Smash Bros. Game Download for Nintendo 3DS

Gameplay

Classic solo mode puts fighters through a variety of challenges, some of which require teaming up
Smash mode lets you play with up to four people (each needs their own 3DS); you can customize rules, time limit, battlefield, and more

Exclusive Mode

In Smash Run, up to four players get five minutes to battle their way through as many enemies as possible. As baddies are defeated, they leave behind power-ups. After five minutes, the four players are turned against each other for a fight to the finish, so those power-ups can come in handy.
