About this game

Agent 8 wakes on a subway platform without memories, deep beneath the world of Splatoon 2. In Octo Expansion, you take this Octoling through experimental facilities and work towards an escape to the surface. The adventure contains 80 missions, with weapons and mechanical hazards standing between you and the next completed trial. The subway connects these testing grounds, giving the journey a station-based structure. Alongside the challenges, the story explores familiar Splatoon characters from another angle. This is additional single-player content for Splatoon 2, so the full base game is required to play.

9.2 / 10Nintendo Switch

A fit for players who want Splatoon's world framed around individual trials and an escape story.

The experimental-stage structure gives players a reason to focus on overcoming one obstacle setup at a time. Returning-character stories may add motivation for existing fans, while the solo format makes this a different commitment from playing together.

Strengths

  • Subway-linked trials give the escape objective a concrete structure.
  • Additional character stories may reward an interest in Splatoon's setting.

Who it is for: Players interested in solo obstacle challenges and another perspective on Splatoon characters.

Play notes: This expansion requires Splatoon 2, with DLC compatible with the base game's region.

DLC and base-game region compatibility is an important setup condition because an incompatible pairing can prevent the content from appearing.
