To celebrate the game’s first anniversary.
As the Nintendo Switch celebrated its first birthday, it also celebrated the anniversary of one of its launch games, The Legend of Zelda: Breath of the Wild. As part of the celebrations, gamers in Japan will be getting a limited edition soundtrack featuring all the music composed for the game including the two DLCs released for it.
The limited edition OST collection will feature all 211 original songs made for the game. The 5-CD soundtrack will also come in a special packaging that will have a Play Button music player built into the packaging that once pressed will play 15 pre-loaded tracks from the game. There will also be a standard edition featuring just the CDs.
The bad news though is that the soundtrack will only be released in Japan on April 25th and there are currently no plans of releasing it in international markets so if you want the soundtrack collection you may have to import it directly from Japan.
