Rhythm Heaven Megamix

Rhythm Heaven: The best + is the fourth game in the Rhythm Heaven franchise. It will be released June 11th, 2015 in Japan, and has yet to be announced for an international release.

This game will include 70 minigames from the previous three Rhythm Heaven games, and 30 new minigames will be added.

Story Mode
In the storymode of this game, the player helps a character named Tebiri back to their hometown by playing and beating each rhythm based minigame that is presented to the player. It seems old games that were taken from previous titles now have different music, rhythms and also themes. A game could possibly have more than one new theme.

Co-op Mode
This game will feature co-op, in the form of being able to play specific minigames in an up to four player mode. This will use the Download Play feature, meaning some games can be played even if only one person owns the game.
