Super Smash Bros. Brawl (大乱闘スマッシュブラザーズX Dairantō Sumasshu Burazāzu Ekkusu?, lit. "Great Melee Smash Brothers X"), often shortened to SSBB or Brawl, is the third installment in the Super Smash Bros. series published by Nintendo. Like the other games in the series, it features a diverse roster of characters from Nintendo and its second parties to fight in various kinds of matches. However, Brawl is the first Super Smash Bros. game to feature third-party characters. Most of the game's music is made up of arranged versions of pieces that originated in previously released Nintendo video games; though some play exactly as they did in their original games, others are arranged by one of 36 renowned video game composers.
As with its predecessors, Super Smash Bros. Brawl is a departure from traditional fighting games, notably in its simplified move commands and its emphasis on ring-outs over knockouts. Brawl includes a deeper single player mode than its predecessors, known as The Subspace Emissary, this mode is a side-scroller featuring the playable characters and a unique storyline. The storyline of this mode involves characters surviving under the weight of their own histories. Brawl supports multiplayer battles with up to four combatants - and is the first game in its franchise to support online battles through Nintendo Wi-Fi Connection.
