Smash Run

Smash Run is a single-player and multiplayer mode found in Super Smash Bros. for Nintendo 3DS. It strongly resembles the City Trial mode from Kirby Air Ride while including elements of The Subspace Emissary mode in Super Smash Bros. Brawl.

In Smash Run, the player's fighter travels in a large maze-like map and has to fight enemies from various Nintendo games, including some Subspace Army enemies. Before going into battle, players can equip powers, which have a variety of effects, such as being a more powerful attack, temporarily increasing stats, healing, or equipping the player with an item. The player can equip only a certain number of powers based on their weight, the maximum weight being determined by the player's current equipment and the fighter.

While fighting, players can collect several items similar to patches. These stat boosts can increase attack power, special attack power, jumping, or movement speed; there are also special stat boosts which increase all stats. After five minutes, players are shown their final stats, courtesy of the stat boosts they collected, and they are pitted in one of several modes, similar to the Stadiums from City Trial, in which players must fulfill the given conditions to win.
