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
I still have yet to understand what is new in Splatoon 3. I play 2 casually, just for a few pvp matches every so often, and it's good as is
It's an iterative series, each game building on the predecessor's mechanics, so there's not any one major twist. But there are a lot of little things that add up. The new movement techniques are great, Salmon Run has been significantly expanded, and just in general the QoL is night and day.
Also, the fact that Ink Armor, Sting Ray, and Main Power Up are not in the game might be the true biggest step forward. S3's meta is in a pretty good spot now.
The second game even repurposed large parts of the not-particularly-impressive campaign of the first game. They weren't going to fool me again by making me buy the same game a third time.
Large parts? It's been a while since I played Octo Canyon, but I'm pretty sure the only thing that reappeared from Valley was the Octostomp boss, but it's a different fight anyway so not really.
