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.
Melee
Donkey Kong
Playing as Donkey Kong, situate him anywhere on the stage. When the Fighting Wire Frames begin approaching Donkey Kong, use his Down Special Move, the Hand Slap. Any Fighting Wire Frames in the radius of this move should be knocked out instantly.
Dr. Mario
Playing as Dr. Mario, spam his Down Special Move, the Dr. Tornado, back and forth along the stage.
Falco
Playing as Falco, spam his Side Special Move, the Falco Phantasm, back and forth along the stage.
An alternative method while using Falco is to sit on the far right side of the stage and continually spam his blaster. On occasion a wireframe may obtain a starman. While the starman is in effect, spam his Side Special Move, the Falco Phantasm, back and forth until the starman wears off. Then continue to sit on the right side and spam his blaster. This will not work with Fox due to the fact that Fox's blaster does not flinch the enemy. It is possible to complete the challenge and not get hit using this method.
Fox
Playing as Fox, spam his Side Special Move, the Fox Illusion, back and forth along the stage.
Kirby
Playing as Kirby, situate him on the edge of a main platform, facing inwards, and use his Up Special Move, the Final Cutter. If necessary, roll to the other side of the platform to avoid a Bob-omb or similar hazard.
Luigi
Playing as Luigi, spam his Down Special Move, the Luigi Cyclone, back and forth along the stage.
Mario
Playing as Mario, spam his Down Special Move, the Mario Tornado, back and forth along the stage.
Mewtwo
Playing as Mewtwo, situate it on the edge of a main platform and use its Standard Special Move, the Shadow Ball. Any Fighting Wire Frames in the radius of this move will be damaged. If Mewtwo is damaged, launch the fully-charged Shadow Ball, and return to the edge of the main platform to start over.
Screw Attack
Hold off the wire frames until you get a screw attack ball. While this would be useless against real fighters the wireframes will be KO'd on contact. If you can hold on to the item the whole time, you can easily get through 15 minutes mostly untouched.
Brawl
Lucario
This strategy requires two players. Both players must be Lucario. Both players must stand beside each other using Lucario's standard special attack. When a Fighting Alloy jumps up to the players, they will be caught between the two attacks and will not be able to move. <youtube width="300">l7REN8iQARw</youtube>
