Nintendo has announced the surprise release of Rhythm Heaven Megamix on Nintendo 3DS eShop via its E3 Treehouse livestream and official launch trailer. Megamix combines minigames from previous entries in the series, including the never localized Game Boy Advance game. These games, along with some brand new ones, are wrapped up in a new story mode, while a multiplayer mode, a first for the series, can be played with only a single game download. A free demo has also been made available for download, so players are able to try before they buy. Check out the launch trailer below for a better look at the title:
