Rayman Rush is a remake of Rayman M developed by Ubisoft Shanghai only for the Sony PlayStation in 2002. While it was the same game as Rayman M both in terms of plot and concept, only the racing half of the game was ported. Also there are a lot of other differences, probably due to the PlayStation's limited specifications, resulting in a poor conversion.
The Teensies are replaced by a pink female Globox called Globette. She uses Tily's sound clips sped down, and for an unknown reason, shares the musical theme of Dark Globox, a character who only appears in the GameCube and Xbox versions of Rayman Arena. Because of this, the player starts with only four characters in this version.
The menu music is lower in pitch.
Each character is now equipped with freeze bullets like in the Rayman M battle game Lum Spring, which freezes a character for five seconds when shot.
Some of Rayman M's bonus levels now use textures and are made into proper levels, most notably the Canopy.
It was revealed in March 2013, that the game can be completed at 100%. Until then only 99.2% was known to be possible. The percentage most likely has some kind of connection with the time records made through the game.
