A large number of
competitive Super Smash Bros. Melee players were disappointed upon the release of its sequel
Brawl six-and-a-half years after the release of
Melee. The general consensus among competitive players was that the latter game's developers had reworked the older battling system to better appeal to
casual gamers, by making the attacks and movement of the game significantly slower in general and adding a greater degree of randomness, luck, and unpredictability, in contrast to
Melee, which has more straightforward, skill-based gameplay. Of particular infamy was a new "tripping" mechanic, by which a character occasionally and randomly slips and falls when changing their direction while running.
Project M first began as a development project to rework the character
Falco to play like he did in
Melee. The designers' goal at the time was for the game to be accessible to newcomers and encourage people to get better at the game, which was accomplished by creating a character roster that is more balanced. It was later given a solid date of February 7, 2011. A patch was later created to fix the demo's bugs and fine-tune the player's control of their movement direction after being attacked. By the release of the game's second demo in March 2011, the team's goals for the mod had expanded to a total overhaul of
Brawl to better match
Melees gameplay mechanics. The second demo, released on April 15, 2012, added four new characters as well as more stages and changes in multiple characters' gameplay mechanics. Players of this second demo reported a number of bugs, but these were fixed shortly afterwards in version 2.1. stage updates, and
palette swaps for the characters. Version 2.5 was released on December 28. Originally as part of an April Fool's Day joke, the PMDT announced that a new "Turbo mode"—inspired by a
YouTube video called "Melee Impossible" that showed off powerful combos—would be featured in the upcoming version 3.0. The designers set up a Turbo Tuesday video series showing off the mode with various characters, such as Mario and
Ike, once a week. A 2.6 demo was announced on June 26, 2013, and it was released on July 17, 2013. The designers hoped to feature the Turbo mode in this update, but it was not ready in time. The designers added new alternate costumes for a number of characters, including
Dr. Mario, who was previously cut from
Brawl, for
Mario. It was given a release date of December 9, 2013 with a final character count of 41, more than any previous
Super Smash Bros. game at the time. Senior designer Corey Archer stated that there would probably be only one more update before he considers
Project M complete; he suggested that this update may contain new Nintendo characters. This revision refines the game's user interface, adds new stages and costumes, adds a few new original musical pieces, redesigns several stages from the original
Super Smash Bros. using new HD visuals, and implements new modes such as a
debug mode and "All-Star Versus," a mode allowing players to use a different character on every life. A public beta of Version 3.6 was released on June 23, 2015. It added more costumes and stages, new music, a new in-game announcer, and the ability for players to choose between the modified and unmodified versions of stages before battle among other changes. This was the first non-demo version of
Project M which has had a public beta before final release. Version 3.6 was officially released on August 16, 2015, and included even more additional content on top of what was present in the Beta release. Included were additional balance stages, a brand new Wario Land stage, more music, a new announcer to replace the one used in the Beta and various tweaks and fixes to bugs and errors found during the 3.6 Beta period. On December 1, 2015, the PMDT announced it would cease further development of
Project M, effective immediately, in favor of beginning development on an original project. The development team denied allegations that legal threats from
Nintendo were the cause of the project's termination. According to the team's attorney and business consultant, Ryan Morrison, the decision was not made as a result of a cease-and-desist notice or legal action by Nintendo. One member of the development team stated that the mod's cancellation was to prevent future
legal issues. A few members of the PMDT were later hired by game studio Wavedash Games who was developing
Icons: Combat Arena, a fighting game with similar mechanics to
Super Smash Bros.. After Nintendo sent a cease and desist letter to tournament organizer
The Big House for their use of the Slippi emulator in their 2020
Melee tournament,
Project M's official website was updated for the first time in several years, voicing support for the
Smash Bros. community and linking to a mod derived from
Project M, called
Project+.
Characters Project M includes a number of adjustments and tweaks intended to make the characters from
Super Smash Bros. Melee and
Super Smash Bros. Brawl more balanced, as well as add touches that felt more true to their games of origin. For example, the staff felt that the character
Wario in
Brawl took too much influence from the
WarioWare series of games and not enough from his older appearances in the
Wario Land series of games, so they changed him to better reflect the
Wario Land games.
Mario was redesigned to be a cross between his
Melee incarnation and his heavier-hitting clone from the same game,
Dr. Mario.
Peach was changed to make her turnip attacks more similar to
Melee than in
Brawl, after
Brawls advent had diminished their usefulness.
Bowser, a character who was generally not considered viable for tournament play in previous games, was given armor and increased attack power and made larger. These adjustments gave him the ability to reach enemies easier while making him an easier target for opponents.
Yoshi was given an improved recovery and defense. While
Ganondorf's strength was changed to function closer to that of his appearance in
Melee, his neutral special has also been changed to a floating descent in the air and a backhand to deflect projectiles on the ground. Additionally, the characters Mewtwo and
Roy, who had been present in
Melee but were cut from the cast in
Brawl, were added back to the roster and given new abilities to make the previously low-tier characters more viable. Before the project was discontinued, several newcomers were planned for addition, including
Knuckles the Echidna from
Sonic the Hedgehog,
Lyn from
Fire Emblem, and
Isaac from
Golden Sun. A development build containing these characters was leaked on
4chan in the aftermath of the project's discontinuation. However, Knuckles would later be added to
Project M's spiritual successor,
Project+. ==Reception==
