The Great Maze

The Great Maze is the final level of Super Smash Bros. Brawl Subspace Emissary. After the whole Super Smash Bros. World is sent to Subspace, Tabuu combines all the levels of the game and mixes them all together to create one large maze which has parts from all the levels all the characters have been in. The heroes of the game are forced to go through this large maze. However, to beat this level, the player must not go to a goal. To beat it, the player must fight Evil Clone versions of all the characters in the game (excluding Toon Link, Wolf, Sonic and Jigglypuff). Aside from that, the player must also defeat all the bosses encountered in the game.

There is no specific order the player must beat all the enemies – the player can also choose to play as any character he or she wants. Also, there are various Check Points throughout the maze. The checkpoints are indicated by the the Smash Bros. emblem mounted on a trophy stand. After the player has defeated all the "dark" characters and all the bosses again, the player will then open a large red door which leads the player to Tabuu and the Final Battle begins. After the player beats Tabuu, the Great Maze is spread apart and all the levels and locations of the Smash World are returned to their normal state. A map of the Great Maze can be accessed any time by pressing the Start button.
