I’m sure there’s a fair amount of you still playing the original Splatoon for the Wii U and if you are then you need to be aware that the SplatNet service for the game will end on September 30th. However, as expected, the online multiplayer will still be available so you can play online against other opponents until your heart is content.
[Notice] The SplatNet service for the Splatoon game on the Wii U system will be permanently closed on September 30th, 2017. Online multiplayer battles will still be available, as this update only affects the SplatNet service. We sincerely thank all players for using this companion site for the original Splatoon game.
Thanks to MasterPikachu6 for the tip!

Wii U did his best. But he didn’t conquer the attention from many, many people.
The Wii U era is going to end. It’s time to Switch and look for the future.
I didn’t even know the first game had a Splatnet. -5 points from the advertising department.

So you just thought Nintendo named the service on Switch “SplatNet 2” for the heck of it? lol it has a 2 for a reason…
