The sequel to The Legend of Zelda: Breath of the Wild – now known as The Legend of Zelda: Tears of the Kingdom – was such a tightly-guarded secret within Nintendo's corridors that the vast majority of employees only found out about the game's existence along with the fans.
Nintendo of America ex-marketing and PR leads Kit Ellis and Krysta Yang (formerly the director of social media marketing and original content, and senior manager of creator relations and original content, respectively) recall that the open-world sequel was perhaps the most top secret project in all of their years working at the company, courtesy of a recent YouTube video.
