Big Battlefield (SSB4)
From SmashWiki, the Super Smash Bros. wiki
Big Battlefield is, as its name implies, a bigger version of Battlefield, specifically designed for 8-Player Smash. With respect to the original stage, the main platform is wider and there are six floating platforms instead of three, arranged in a pyramid formation. While it is designed for more than four players, Big Battlefield is available in normal Smash matches as well.
Big Battlefield shares all of Battlefield's My Music tracks.
Big Battlefield's Ω form is exactly identical to Battlefield's.
Big Battlefield is banned from tournaments, the reason being that it is simply too big for a normal match; faster characters can abuse the size of the stage to run away and win by Time out. Additionally, the platform layout allows Circle Camping. However, the stage's size can be considered acceptable for 3 vs 3 or 4 vs 4 matches.
