15-Minute Smash
15-Minute Melee and 15-Minute Brawl are Multi-Man modes in Super Smash Bros. Melee and Brawl, respectively. They challenge the player to defeat as many opponents as possible (Fighting Wire Frames in Melee, and Fighting Alloys in Brawl) within 15 minutes without falling from the stage or self-destructing. These are arguably two of the more difficult Multi-Man Melees and Brawls, though simple strategies such as spamming a certain move or evading the opponents altogether will suffice.
The high scores of 15-Minute Melee and Brawl depend on whether or not the match is cleared. If it is cleared, a record is made of the amount of opponents knocked out. If it is not cleared, a record is made of the length of time which the character lasted.
Strategies
Most of the simpler strategies for the 15-Minute Melee and 15-Minute Brawl involve spamming a certain move of the character. It is also recommended to ignore any kind of item, especially those which are explosive.
