Super Smash Bros. Brawl/Stages

Battlefield
The Battlefield stage is one of the most basic stages in the game and a staple of the Super Smash Bros. series. This time around, rather than floating in a dark void, the level has an ancient ruins theme and floats above a large valley. The time of day changes during gameplay, with the sun rising and setting at regular intervals. The theme is not borrowed from any specific game.

Battleship Halberd
The stage takes place on a small platform that soars around in the skies along with Meta Knight's ship, the Halberd. The platform eventually lands on top of of the Halberd, where players are attacked by a double-barreled battery and a mechanical arm.

Bridge of Eldin
This stage is taken from The Legend of Zelda: Twilight Princess. This stage is completely flat, and sometimes King Bulblin tackles you and throws bombs to the bridge to destroy it, but a portal will bring it back to its place.

Castle Siege
Castle Siege is the first stage of Fire Emblem and it has three known scenes of battle:
 * Midst of Battle - The midst of battle is the first scene and it takes place in the outside castle. Here you can see the castle receiving really heavy damage.
 * Throne Room - After time passes the floor shatters and you enter to the throne room. In this place you can destroy the stone statues.
 * Underground - The underground is yet to be exposed.

Delfino Plaza
Delfino Plaza has the players fighting on a colorful floating platform that soars above the central hub of Super Mario Sunshine. After a "thrilling landing", the fight takes place in one of several locations on the island, which include the main square and the fountain by the docks. The flightpath follows a repeating pattern.

Lylat Cruise
The Lylat Cruiser stage is a simple stage where characters fight on top of the Pleiades. It has one main platform and three platforms attached to the ship. The platforms don't change, but the background changes constantly.

Mario Kart
(Unconfirmed name)

The Mario Kart level is a lot like the Mute City level from Super Smash Bros. Melee. It involves characters flying over a race track and doging Shy-Guys  driving Go-karts. This level has been confirmed, but may change later in the development of the game.

Pokémon Stadium 2
The new Pokémon stadium is very similar to the Super Smash Bros. Melee level. While the background has been changed a bit, it still has two small floating platforms over the giant Poké Ball.

The terrain can now transform into "Electric", "Ground", "Flying", and "Ice".

Rumble Falls
This stage is very similar to Icicle Mountain from Super Smash Bros. Melee based on the fact that the screen will slowly scroll upwards, but this is with a Donkey Kong theme.

Shadow Moses Island
The Metal Gear level is based on the helipad area of Shadow Moses Island from Metal Gear Solid. The level has high walls on the left and right that must be destroyed before characters can be smashed off the screen in those directions. A spotlight will search around the area, and, when a character is spotted, the character will pause and an exclamation mark will appear above its head. Occasionally, a Metal Gear will appear from the background. Snake will also receive communications about his opponents on this level.

Skyworld
This stage is the Kid Icarus stage. In this stage the floor's crumbling construction makes it easy to shatter, giving it a more dangerous touch. The floor regenerates quickly.

Smashville
Normally a nice, peaceful, and quiet place, this stage is taken from Animal Crossing. The changing scenery from day to night (and vice versa) is determined by your Wii's internal clock. Another feature is that when you play this stage a Saturday at 8PM a live performance will take place behind the stage.

WarioWare
This wacky stage, inspired by the game which shares its name, has the players not only fighting each other, but also having to contend with the stage, which changes into different WarioWare microgames that appear. Players are rewarded if they successfully complete a microgame.

Yoshi's Island
The Yoshi's Island stage has players battling in an area that changes seasons.
