Brawl+ is a gameplay mod designed to make Super Smash Bros. Brawl more competitive. Among the first gameplay mods released to the public, Brawl+ attained some niche appeal amongst the Smash community due to its gameplay changes. However, as the first mod of Brawl to undo many of the game's changes to more closely match Melee, Brawl+ was frequently controversial amongst smashers, primarily over what the mod's intentions were, with a number of critics referring to the game as "Melee 2.0". Brawl+'s own staff also reportedly became antagonistic with one another due to the lack of a defined goal for the mod.
Despite the controversy surrounding the mod, Brawl+ was the first gameplay mod of Brawl to develop its own tournament scene, and it was featured as a side event at some tournaments, such as Apex 2010 and S.N.E.S..
Brawl+'s last release, version 7.0.3, was released in 2010, with most of its staff having moved onto the development of Brawl+'s spiritual successor, Project M. As such, development of Brawl+ is ceased, and no new releases of it are expected. In the present, Brawl+ is mostly viewed as a curiosity for players who want to see how the Brawl hacking scene started.
