Super Smash Bros. (大乱闘スマッシュブラザーズ, lit. "Great Melee Smash Brothers"), is a series of fighting games published by Nintendo, featuring characters from established video games. The gameplay differs from traditional fighters for focusing on knocking opponents out of the stage instead of depleting life bars. The original Super Smash Bros., released in 1999 on Nintendo 64, had a small budget and was originally a Japan-only release, but its domestic success led to a worldwide release. The series achieved even greater success with Super Smash Bros. Melee, released in 2001 for the Nintendo GameCube, becoming the best-selling game on that system. HAL Laboratory developed the first two titles in the series.
The game features many characters from Nintendo's most popular games, like Mario, Fox McCloud Link, Kirby, Samus Aran and Pikachu. The original Super Smash Bros. had 12 characters, and the number rose to 25 characters in Melee and 35 in Brawl. Some characters are able to transform into different forms that have different styles of play and sets of moves. The games also feature non-playable Nintendo characters, like Ridley and Petey Piranha. In Brawl, two third-party characters were added: Solid Snake and Sonic the Hedgehog.
