15-Minute Melee

15-Minute Melee is a Multi-Man Smash present exclusively in Super Smash Flash which originates from the Super Smash Bros. series. It challenges the player to defeat as many opponents as possible within 15 minutes without falling from the stage, self-destructing or being KO'd.

In Super Smash Flash
This mode is called 15-Minute Melee, as it was called in Super Smash Bros. Melee. As with other Multi-Man modes, 15-Minute Melee is always played on and the opponents are always the Fighting Silhouette Team. It is a more advanced version of 3-Minute Melee and is one of the most challenging Multi-Man modes as throughout the 15 minutes, the player can accumulate a great amount of damage and eventually be easily KO'd by a single attack. A good strategy would be to wander around, spam attacks, or simply toy with the opponents and let the timer run out rather than actually fight them. Unlike Melee, opponents are always at the same level of aggressiveness and "weight" and does not increase as the time goes on.

Though opponents are light and more prone to being KO'd, SSF physics make them a bit harder to launch off the stage with a single attack other than an up attack or a projectile. Additionally, some opponents have access to different moves that allow them to recover with ease and shoot projectiles, which considerably increases the challenge.
