Fourside

Fourside is a place in the EarthBound series. It also appears as an unlockable stage in Super Smash Bros. Melee. The stage is set high on the skyscrapers of Fourside. Players have to be carefully not to fall into the gaps between the buildings. It had a giant U.F.O that would occasionally show up on screen, and players could jump on top of the U.F.O.

The stage could be unlocked by playing one hundred matches in VS mode.

Trivia

 * Fourside's name comes from its being the fourth stage in EarthBound (where it initially appeared), as all EarthBound world names come from the number of world they were chronologically traversed in the game.
