After 2 INK-credible years of Splatoon 3, regular updates will come to a close. Don't worry! Splatoween, Frosty Fest, Spring Fest, and Summer Nights will continue with some returning themes!
Updates for weapon adjustments will be released as needed.
Big Run, Eggstra Work, and Monthly Challenges will continue for the time being.
Also they just released a video celebrating each splat-fest: https://www.youtube.com/watch?v=cd3qYJRnI7E
Oh, did you think the headline meant they were shutting S3 down? Servers will remain up for the foreseeable future, and they'll even still run seasonal Splatfest and Big Run events. They're just done with content updates.
My mistake, I've made a mountain of a molehill.
