Splatoon 2: Octo Expansion is an extensive new single-player mode for Splatoon 2!

You are Agent 8, a new character who resembles an Octoling. She wakes up on the platform of a dark subway station with no memory of who she is.

Navigate through a vast underground world across a total of 80 test facilities and prove your skills in a variety of missions.

Look forward to new stories that shed light on popular characters. You might think you know everything about the world of Splatoon, but it is as deep as the ocean.

If you manage to escape the perilous depths, you can participate in multiplayer matches as an Octoling!

When you purchase "Octo Expansion" in the Switch eShop, you will immediately receive Octo-themed gear to use in battles.
