Battlefield (戦場 Senjō) is a special stage in Super Smash Bros. Melee that is unlocked by clearing All Star Mode on any difficulty, with any character. The field's main part is flat, just like Final Destination, but not as long. Three smaller platforms are suspended in a pyramid pattern above the main platform. Since this level is considered fair, it is a tournament-legal stage. It shares similarities to Final Destination that the background is abstract and changes shape and color constantly. Gravity is lowered significantly on this stage in the Adventure Mode fight against the Fighting Wire Frames.
In Classic mode, players fight a metal character on this stage. In Adventure, they fight the Fighting Wire Frames, Metal Mario, and Metal Luigi. In All-Star, players fight Mewtwo and another character. In Multi-Man Melee, players fight the Fighting Wire Frames.
Recovery on this stage is difficult due to the very thin edges on either end. If players misses their edge with a vertical up B, they go underneath the stage to a possible KO. It is more difficult to sweet spot the edge using characters such as Marth and Fox on this stage. There is one exception to this: with Falco (and more difficult with Fox), it is possible to platform cancel his Falco Phantasm (or Fox Illusion) move on one of the bottom platforms. Then, the player can choose to immediately phantasm to the next platform, which also platform cancels.
Battlefield is also infamous for its "glitchy" ledges. It is said that, unlike other stages, if players attempt to sweet spot the ledge and hold toward the ledge as they do so, they may often miss the ledge when it clearly appears they should have been able to grab it. Also, there have been cases where 'miracle ledge grabs' have been performed in cases where it did not appear as if the character should have survived.
Also, there is a technique that allows Captain Falcon to sweet-spot the ledge almost immediately after starting his up special, if he is in a specific area of the stage, somewhere between the ledge and the ceiling underneath. It is, however, extremely difficut to perform and thus is not considered practical in most situations. A demonstration and in-depth explanation can be seen in this video.
