Flat Zone 2
From the Super Mario Wiki
Flat Zone 2 is an unlockable stage in Super Smash Bros. Brawl, acting as the second Game & Watch stage in the Super Smash Bros. series, the first being Flat Zone from Super Smash Bros. Melee. This stage also reappears in Super Smash Bros. for 3DS, also as an unlockable stage. In both games, this stage is unlocked by unlocking Mr. Game & Watch, but requires also to have completed the 35 first challenges in Super Smash Bros. for 3DS.
As with Flat Zone, the stage is set inside a Widescreen-series model with Super Smash Bros. written at the top. Also as Flat Zone, the characters are flattened.
Unlike the original Flat Zone, Flat Zone 2 normally shifts to different Game & Watch game scenarios, rather than staying in one area the entire battle. Some of the scenarios known are Fire (1981 version), Oil Panic's bottom screen (1982), Lion (1981), and Chef.
The stage is always set in Fixed Camera mode regardless of Special Brawl settings, as opposed to the original Flat Zone which frequently has its camera zoom in on players.
The Final Destination variation of the stage in Super Smash Bros. for Nintendo 3DS is set on the roof of the gas station in the Oil Panic portion of the stage.
