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. They 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 100 matches in VS mode.
