Project M is a video game modification ("mod") of the 2008 Wii fighting game Super Smash Bros. Brawl, created by the community group known as the Project M Development Team (PMDT or PMDev Team; previously known as the Project M Back Room). It is designed to retool Brawl to play more like its two predecessors, Super Smash Bros. (1999) and Super Smash Bros. Melee (2001), in response to fan objections to Brawl's physics, slower-paced gameplay, larger use of chance elements, and mechanics of certain attacks. Project M brings back the characters Mewtwo and Roy, who were present in Melee but did not return for Brawl. 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.
