The game's first demo build was released on February 7, 2011, and development continued until December 1, 2015, when the PMDT announced it would cease further development of Project M.

In addition, it features a new art style for in-game menus and allows players to choose certain characters individually when they are only accessible as extensions of other ones in Brawl.ĭevelopment started in early 2010 with the goals of reworking the character Falco Lombardi to mechanically play like he did in Melee and increasing the accessibility of the gameplay style, but the project quickly evolved to a full-scale reworking of Brawl. Mario (albeit as a palette swap of Mario), Mewtwo, and Roy, who were present in Melee but were cut from Brawl. Project M reintroduces the characters Dr. Melee (2001), in response to fan objections to Brawl 's physics, slower-paced gameplay, larger use of chance elements, and mechanics of certain attacks. It is designed to retool Brawl to play more like its two predecessors, Super Smash Bros. Brawl for the Wii, created by the community group known as the Project M Development Team (PMDT previously known as the Project M Back Room).

Project M is a mod of the 2008 fighting game Super Smash Bros.
