List of post-release content in Splatoon 2

Post-release content is additional content released for after the game's release date. Nintendo frequently releases new weapons, stages, modes, features, and gear. Usually, Nintendo announces the release date of upcoming content via their social media accounts. An in-game news announcement introduces the new content when it has been released. Interestingly, most additional content is already in Splatoon 2, waiting to be unlocked by Nintendo. Nintendo has claimed that new content will continue to be released for "about a year".
