Super Smash Bros. Brawl is the third installment in the Super Smash Bros. series and the follow-up to Super Smash Bros. Melee. This edition introduces super attacks referred to as final smashes: activated by destroying smash balls, these feature powerful and often unstoppable attacks, regularly introducing a major transformation of the character. This edition also introduces a brand new adventure mode in The Subspace Emissary which is a side-scrolling adventure in the style of a platformer. It retains all basic mechanics of the Super Smash Bros. series, such as a damage meter, stocks, and Smash-style attacks.
