Welcome to a fight for the eras where everything can occur, anybody can humiliate and all stakes are off. In multiplayer games characters from every one Nintendo worlds convene in Nintendo locales to duke it out. In the solo mode called "The Subspace Emissary," the world of Smash Bros. is attacked by an entity called the Ancient Minister and his army of persons, called “The Primid.” usually, characters comes alive in the world of Smash Bros. to do battle and then turn back into trophies when defeated. However, the Ancient Minister starts turning natures into trophies to harness their power, then detonates bombs that suck pieces of the world back into his realm of Subspace. Eventually, all the characters must work together to defeat the invading creatures from Subspace - this is talented by playing through side-scrolling levels.
