Big Battlefield (SSBU)
From SmashWiki, the Super Smash Bros. wiki
Big Battlefield is a bigger version of Battlefield, originally designed for 8-Player Smash. With respect to the original Battlefield, the main platform of Big Battlefield is wider and there are six floating platforms instead of three, arranged in a pyramid formation.
Visually, Big Battlefield still takes place in a futuristic ruins setting, with crumbled buildings on floating islands in the background. However, it now floats above a large waterfall, and large chunks of ice or crystal are present both below and on the right side of the stage.
