Announced at E3 2001, Fourside (フォーサイド, Fourside) is an unlockable stage in Super Smash Bros. Melee, unlocked by playing 100 battles in Vs. mode. It is also Ness's home stage, but you face Pichu and its teammates here in All-Star mode. All of the pits in this stage minus the farthest left and right ones are narrow, providing wall jumpers a decent advantage.
