Battlefield (also known as the Fighting Polygon stage and dubbed in the Japanese version by the announcer as the "Battle Stage") is a stage in Super Smash Bros. home to the Fighting Polygon Team in the 1P Game. Battlefield is a simple three-platform stage with a long solid landmass below. It is overall smaller than the Melee,Brawl, SSB4and Ultimateversions, but also lacks the Melee version's infamous ledges on its main platform. It also has a higher ceiling than its Melee counterpart. The only way to use the stage for a multi-player match is through hacking. The versions of Battlefield which have appeared in later Smash games are legally playable.
The name "Battlefield" is reverse-applied to this stage, as redesigns of this stage in both Melee and Brawl share that name. In Japan, the official name this stage is デュエルゾーン (Duel Zone), while the versions in Melee and Brawl were named 戦場 (,Senjō?, Battlefield).
This Battlefield is the only one that can’t be played in VS mode through ordinary means.
