Square Enix had more amazing announcements during the Nintendo Switch E3 2019 press conference. The first is that an unreleased Mana title, Seiken Densetsu 3: Trials of Mana is receiving a full remake, and will get a global release: Trials of Mana. The 1995 hit in Japan has six characters, and players can customize their own party of three, for different story experiences.
It is presently in the works, but if you want your Mana fix now, Collection of Mana is now available on the Nintendo eShop for 39.99, with a physical release being dropped on August 27th. Collection of Mana has the first three Mana games: Final Fantasy: Adventure, Secret of Mana, and Trials of Mana/Seiken Densetsu 3. Secret of Mana in the Collection will have local multiplayer with up to three players as well.
