To start the Splatoon 3 Story Mode, players need to follow Cuttlefish underground via the sewer cover – press ZL to enter. This will immediately take you to the story mode cutscene.

What’s the Basic Plot?

In Splatoon 3 story mode named “Return of the Mammalians”, you play as Agent 3 who is a part of the New Squidbeak Splatoon. Your mission is to recover the Great Zapfish which will power Splatsville. Cuttlefish tells you that it’s the Octarians again. Take up this job offer and you can save the world. You will also get a brand new Hero Suit to help you fight enemies. And that’s it! Your solo campaign journey will begin.
